Motor: 60W, 50-600 rpm. Torque: 0.95 Nm – nearly 3.5× the PGR-3. Best For: Industrial R&D groups, contract labs, essential oil distillation. Upgrade from PGR-3: More robust stirring, 5 necks allow additional monitoring probes. 3. FPGR-10 (10 Liters) – The Sweet Spot (Most Popular) Dimensions: 650×650×1900 mm – requires dedicated floor space or cart. Motor: 140W, 50-600 rpm – same motor as 30L and 50L models. Torque: 2.23 Nm – capable of moderate viscosities. Neck Count: 6 – full instrumentation (stirrer, condenser, addition funnel, thermometer, gas inlet, sampling). Best For: New material synthesis, pharmaceutical intermediates, pilot studies before 50L scale-up. ROI Advantage: Shares motor and torque with larger units, meaning process parameters (speed, power draw) scale predictably to 30L and 50L. 4. PGR-30 (30 Liters) – The Pilot Plant Workhorse Dimensions: 700×500×2100 mm. Inner vessel diameter: 330 mm vs. FPGR-10's 230 mm – much larger surface area. Vessel height: 730 mm – deeper immersion for coils. Best For: Kilo-to multi-kilo batch production, contract manufacturing. Consideration: Requires 220V power and substantial ceiling height. 5. PGR-50 (50 Liters) – The Production Starter Dimensions: 800×600×2300 mm. Torque still 2.23 Nm – adequate for low-to-medium viscosity at this scale. Best For: Small-batch specialty chemicals, cosmetic emulsions, food extracts. Note: At 50L, glass weight becomes significant; ensure floor loading capacity. 6. PGR-100 (100 Liters) – Industrial Scale Motor: 250W, torque increased to 3.98 Nm. Cover diameter: 340 mm – large opening for cleaning and solid charging. Best For: Commercial production of high-value pharmaceuticals, fine chemicals. 7. PGR-200 (200 Liters) – Maximum Glass Reactor Dimensions: 1200×900×3200 mm – requires forklift for installation. Motor: 750W, torque 6.37 Nm – nearly triple the 50L model. Best For: Full-scale manufacturing where stainless steel is unsuitable (acidic media, visual monitoring required). Limitation: Maximum vacuum remains 0.098 MPa – identical to 3L model, demonstrating excellent seal design consistency across the range. Matching Reactor to Application Application: New Material Synthesis (Nanoparticles, MOFs, Battery Materials) Recommended: FPGR-10 or PGR-30 Reason: Requires 6 necks for full instrumentation; visual monitoring critical; moderate torque sufficient. Application: Strong Acid Reactions (HCl, H2SO4, Aqua Regia) Recommended: Any PGR model (all use borosilicate glass + PTFE) Reason: Only glass and PTFE contact media – no metal corrosion. Application: High-Viscosity Polymers (＞10,000 cP) Recommended: PGR-5 (small scale) or PGR-100/PGR-200 (large scale) Reason: Lower viscosity limits at mid-range. For 10L scale with high viscosity, consider custom anchor stirrer. Application: Solvent Recovery Under Vacuum Recommended: Any model – all achieve 0.098 MPa Reason: Mechanical sealing maintains vacuum even at speed. ROI Considerations Beyond Purchase Price Factor 1: Scale-Up PredictabilityThe FPGR-10, PGR-30, and PGR-50 share identical 140W motor and 2.23 Nm torque. This means tip speed and power-per-volume scale linearly – a significant advantage for process transfer. Factor 2: Cleaning DowntimeThe separated kettle cover and body design applies to all models. Disassembly time is comparable whether cleaning a 3L or 200L unit – a major labor savings at production scale. Factor 3: Transit Damage ProtectionNTSJ's policy – seller bears transport damage – applies equally to all models. For a 200L reactor, replacement glass could cost thousands. This policy eliminates that risk. Factor 4: Modular Heating/CoolingAll PGR models work with the same circulating water/oil baths and chillers. Your investment in thermal control equipment remains valuable as you scale up. Practical Recommendation Matrix If your batch size is… And your viscosity is… Then choose… 25 liters Low to Medium PGR-100 or PGR-200 Final Recommendation: Start Smart, Scale Confidently For most laboratories and pilot plants, the FPGR-10 (10L) offers the optimal balance: the same 6-neck configuration and motor specification as production-scale 30L and 50L units, but in a manageable 650×650×1900 mm footprint. Begin your process development on the FPGR-10, validate your scale-up parameters, then transfer directly to PGR-30 or PGR-50 without re-engineering your mixing or heating profile. For academic or budget-constrained labs, the PGR-5 provides exceptional value with 5 necks and 0.95 Nm torque – sufficient for 80% of standard organic synthesis tasks. For commercial production requiring maximum throughput, the PGR-200 delivers 200L working volume with 750W of spark-free, frequency-controlled power, backed by the same mechanical sealing and vacuum integrity as the smallest PGR-3. Contact NTSJ today for a consultation. Their engineering team can recommend the correct model based on your specific reaction chemistry, available utilities, and scale-up timeline – and they will customize neck configurations, frame materials, and drive systems to match your exact requirements. With ISO9001 certification, CE marking, and a seller-borne transit damage policy, your glass reactor investment is protected from delivery through decades of reliable service.

Title: Double Jacketed Glass Reactor for New Material Synthesis: Customizable 10L to 200L Solutions from NTSJ Meta Description: Scale your pharmaceutical and chemical processes with NTSJ borosilicate glass reactors. From 3L to 200L, double jacketed designs, PTFE non-dead angle valves, and mechanical sealing for 0.098MPa vacuum. The transition from laboratory research to pilot production is one of the most challenging phases in chemical development. Glass reactors must maintain consistent performance across scales while accommodating evolving process requirements. NTSJ's PGR series of double jacketed glass reactors—ranging from 3 liters to 200 liters—provides a seamless scale-up pathway. This article focuses on applications in new material synthesis, the advantages of customizable configurations, and how the FPGR-10 serves as an ideal bridge between R&D and production. The Scale-Up Advantage: A Coherent Family of Reactors NTSJ offers seven standard models, all sharing common design philosophies while scaling dimensions and power appropriately: Model Volume Best For Motor Power PGR-3 3L Small-scale R&D, method development 40W PGR-5 5L Process optimization, teaching labs 60W PGR-10 10L Pilot studies, new material synthesis 140W PGR-30 30L Small production, kilo-scale batches 140W PGR-50 50L Pilot plant, contract manufacturing 140W PGR-100 100L Production scale 250W PGR-200 200L Commercial manufacturing 750W Notice that the FPGR-10, PGR-30, and PGR-50 share the same motor power (140W) and torque (2.23 Nm), meaning viscosity-handling capability remains consistent as volume increases. Only when moving to 100L does power increase to 250W, and 200L requires 750W. Application Spotlight: New Material Synthesis The FPGR-10 is specifically highlighted for New Material Synthesis. This application category includes: Nanoparticle production: Controlled precipitation and surface modification. Polymer synthesis: Emulsion, suspension, and solution polymerization. Advanced ceramics: Sol-gel processing for battery materials. Composites: Fiber treatment and matrix formation. Specialty chemicals: Additives, stabilizers, and intermediates. Why is the double jacketed glass reactor preferred for these applications? Visual Monitoring: New material reactions often involve color changes or precipitate formation. Glass walls provide uninterrupted observation. Acid Resistance: Many precursor chemicals (e.g., hydrofluoric acid substitutes, titanium tetrachloride) are highly corrosive. Borosilicate glass and PTFE are uniquely resistant. Precise Temperature Control: Double jacket circulation allows isothermal operation or controlled ramping, essential for crystal size uniformity. Customization: Your Reactor, Your Specifications NTSJ's tagline "Customizable" appears repeatedly because it is their primary competitive advantage. Standard customization options include: Neck Configuration:The FPGR-10 has 6 necks on the cover. These can be configured with various port types: Stirrer bearing (center) Condenser connection Addition funnel ports (pressure-equalizing or standard) Thermowell for temperature probe Sampling port Gas inlet/outlet with PTFE valve Material Options: Standard borosilicate glass 3.3 Enhanced thermal shock grades for rapid cycling PTFE-coated internal surfaces for ultra-low adhesion Frame and Drive: Explosion-proof motor option (for flammable atmospheres) Pneumatic/air-driven option (spark-free operation) Custom frame heights for specific benchtop clearances Heating/Cooling Integration:NTSJ can supply complete systems including: Circulating water/oil bath (heating only) Cooling chiller High and low temperature machine (combined heating and cooling) Complete piping and insulation kits Double Jacketed vs. Single Layer Glass Reactor NTSJ produces both types, and understanding the difference guides correct selection: Double Jacketed (Featured in FPGR-10): Outer jacket for circulating thermal fluid Best for precise temperature control Suitable for exothermic or endothermic reactions Can use both heating and cooling fluids Single Layer Glass Reactor: No circulating jacket Typically heated by external mantle or internal coil Lower cost, simpler operation Suitable for ambient or gently heated reactions For new material synthesis, the double jacketed design is almost always preferred due to the need for precise thermal management during crystallization and precipitation steps. The PTFE Discharge System Explained The non-dead angle glass/PTFE discharge valve deserves special attention. Traditional reactors often have "dead legs"—uncirculated zones where product accumulates. The FPGR-10's valve design eliminates this through: Full-port ball valve geometry: When open, the bore diameter matches the vessel outlet. PTFE wetted surfaces: Prevents sticking of viscous materials. Vertical orientation: Gravity-assisted complete draining. For high-value materials (e.g., pharmaceutical intermediates or noble metal compounds), eliminating residue can save thousands of dollars per batch.

Below is a detailed breakdown of the FPGR-10 compared to its closest siblings: Parameter FPGR-10 PGR-5 PGR-30 Volume (L) 10 5 30 Neck No. on Cover 6 5 6 Inner Vessel Dia. (mm) 230 180 330 Outer Vessel Dia. (mm) 290 230 365 Cover Diameter (mm) 265 180 265 Vessel Height (mm) 450 400 730 Motor Power (W) 140 60 140 Vacuum Degree (Mpa) 0.098 0.098 0.098 Rotation Speed (rpm) 50-600 50-600 50-600 Torque (Nm) 2.23 0.95 2.23 Power (V) 220 220 220 Dimension (mm) 650x650x1900 450x450x1200 700x500x2100 The FPGR-10 shares the same powerful 140W motor, 2.23 Nm torque, and 50-600 rpm speed range as the larger 30L model, making it exceptionally capable for viscous reactions despite its smaller footprint. Material Excellence: Borosilicate Glass The FPGR-10 is constructed from high-borosilicate glass. This material is specified for three critical reasons: Chemical Resistance: Resistant to strong acidic properties of materials, including hydrochloric, sulfuric, and nitric acids. Thermal Shock Resistance: Withstands sudden temperature changes without cracking, essential for exothermic reactions. Transparency: Full visibility of the reaction process allows operators to monitor color changes, precipitation, and phase separation in real time. Importantly, the only materials contacting the reaction media are glass and PTFE (polytetrafluoroethylene). This ensures zero cross-contamination and absolute chemical inertness, making the reactor suitable for high-purity pharmaceutical synthesis. Double Jacketed Design for Thermal Control The "double jacketed" designation means the FPGR-10 features an inner vessel (230mm diameter) and an outer jacket (290mm diameter). The space between these two layers circulates heating or cooling media. Compatible Thermal Systems: Heating: Circulating water/oil bath or high and low temperature machine. Cooling: Cooling chiller or high and low temperature machine. This design allows precise temperature control from sub-ambient to elevated temperatures without exposing the reaction media to direct heating elements. The result is safer, more repeatable reaction kinetics. Vacuum Performance and Mechanical Sealing The FPGR-10 achieves a vacuum degree of 0.098 MPa (approximately 980 mbar absolute, or 735 Torr). This is exceptionally high for glass reactors of this size. The secret lies in the mechanical sealing system. Unlike standard PTFE gland seals that leak under dynamic conditions, the mechanical seal maintains high vacuum integrity even when the stirrer is rotating at 600 rpm. This capability is crucial for: Solvent recovery under reduced pressure Oxygen-sensitive reactions Low-temperature evaporative processes Stirring and Motor System The frequency control speed gear motor offers distinct advantages over traditional DC motors: Smooth Running: No cogging or vibration at low speeds. High Torque: 2.23 Nm available across the entire speed range, not just at peak. No Spark: Brushless design eliminates sparking, critical when handling flammable solvents. Noise Free: Quiet operation improves laboratory working conditions. Long Life: Reduced mechanical wear extends service intervals. The stainless steel (SUS) frame and cast aluminum kettle body support provide a stable, vibration-free platform. The elegant appearance belies a robust structure capable of handling the 10L working volume. Discharge Valve and Cleaning The glass/PTFE discharge valve features a non-dead angle design. Traditional globe valves leave residue in the bottom curve; the FPGR-10's design ensures: Fast Emptying: Full bore discharge. No Residue: Complete draining without disassembly. Easy Cleaning: Straight-through path for flushing. The kettle cover separated from kettle body simplifies disassembly, cleaning, and reinstallation—a feature often overlooked but highly valued in multi-product facilities. Conclusion The NTSJ FPGR-10 borosilicate glass reactor combines industrial-grade vacuum performance (0.098MPa), robust mechanical sealing, and precise frequency-controlled stirring in a compact 10L package.

Product Supplied: Chemical Lab Vacuum Rotary Evaporator The rotary evaporator is an indispensable laboratory instrument primarily used for evaporation, concentration, crystallization, drying, separation, and solvent recovery in the medicine, chemical engineering, and biopharmacy industries. Developed on the principle of thermostat heating that enables thin-film evaporation under vacuum negative pressure conditions, this equipment represents a cornerstone technology for modern chemical laboratories and industrial R&D facilities worldwide. How It Works The rotary evaporator employs stepless speed regulation to rotate a glass bottle at a constant speed. As the bottle rotates, the material forms a large-area, balanced thin film on the inner wall of the bottle. A smart thermostat-controlled water bath heats the rotating bottle, facilitating high-speed evaporation under vacuum conditions. The solvent vapor is then cooled by a high-efficiency glass condenser and recovered into a receiving flask. This cyclical process ensures maximum solvent recovery efficiency while maintaining sample integrity throughout the operation. Key Features and Advantages Highly Chemical-Resistant Materials: All components that come into contact with liquids and gases are constructed from premium borosilicate glass 3.3 and PTFE, ensuring exceptional durability and resistance to corrosive chemicals across a wide range of applications. Specialized Low-Noise Motor: An extremely compact motor featuring intermeshed worm and worm gear design delivers precise, quiet, and vibration-free operation, making it ideal for sensitive laboratory environments where stability is critical. Downward-Condensing Vacuum Connection: The unique downward-condensing vacuum connection design guarantees safe and reliable vacuum operation, effectively minimizing the risk of leaks and cross-contamination during extended use. Modular Design Architecture: The individual rotary and water bath modules are designed for effortless maintenance and straightforward future upgrades, significantly extending the equipment's service life and adaptability to evolving laboratory requirements. Auto-Lift with Secure Lock: The evaporating flask features an easy-to-use auto-lift mechanism with a secure locking system, enabling safe and convenient height adjustments during operation without compromising vacuum integrity. Digital Display and Visual Operation: An intuitive digital display shows real-time speed and temperature readings, ensuring straightforward, visual operation for laboratory personnel of all skill levels and reducing operator training time. PID Temperature Controller: A precision PID controller maintains accurate and stable temperature control throughout the evaporation process, which is critical for temperature-sensitive pharmaceutical and biochemical applications. One-Way Check Valve: The integrated 1-way check valve automatically seals when draining the receiving flask, preventing any pressure fluctuation inside the evaporator during the draining process and enabling continuous operation.

A family-owned essential oil producer in Provence, France, wanted to move from traditional copper stills to a more controlled, transparent system for quality assurance. They chose the PGR-200, the largest model in the series, with a 200L inner vessel (600 mm diameter, 1200 mm height) and 750W motor (6.37 Nm torque). The six neck ports allowed simultaneous connection of a steam inlet, fractional column, condenser, decanter, and temperature probes. The double jacket circulated hot oil at 120°C, while the inner vessel operated at slight negative pressure (0.098 MPa max vacuum) to lower boiling points and preserve delicate terpenes. The stainless steel framework with casters supported the 750W motor and full vessel weight safely. Customer Recognition: “We tested the PGR-200 alongside a 200L stainless steel reactor. The glass unit gave us visual confirmation of the oil-water separation interface – we reduced carryover by 40%. The digital speed control let us stir without emulsions. Our lavender oil now meets premium organic certification standards. We’re ordering a second PGR-200 for rosemary."— Pierre Laurent, Owner Key Outcomes: Increased essential oil yield by 18% due to better temperature control. Reduced batch time from 6 hours to 4.5 hours. The transparent vessel became a selling point for customer tours (“see the oil being made"). The French client also appreciated the wooden box packaging, which arrived without any glass damage despite international shipping.
