Nantong Sanjing Chemglass Co., Ltd., an established Chinese manufacturer of chemical glass instruments since 2006, proudly introduces its Ex-Proof Vacuum Rotary Evaporator series. Engineered with explosion-proof electrical apparatus for both motor and control components, this rotary evaporator is specifically designed for environments where safety against flammable solvents and volatile compounds is paramount.
The rotary evaporator operates on a proven principle: the glass flask containing materials rotates under constant temperature heating while the system maintains negative pressure to lower the boiling point of the solvent. As the liquid forms a thin film across the inner surface of the rotating flask, evaporation accelerates significantly. The vapor is then efficiently condensed through the glass coil condenser and collected in the receiving flask. This process makes it uniquely suited for concentration, crystallization, separation, and solvent recovery of heat-sensitive materials.
| Parameter | PR-2 | PR-5 | PR-10 | PR-20 | PR-50 |
|---|---|---|---|---|---|
| Evaporation Flask | 2L / 29# | 5L / 50# | 10L / 95# | 20L / 95# | 50L / 125# |
| Receiving Flask | 1L | 2L / 3L | 5L | 10L + 5L | 10L + 10L |
| Motor Power (W) | 40 | 90 | 120 | 120 | 180 |
| Bath Power (kW) | 1.5 | 2 | 3 | 5 | 5 |
| Rotation Speed (rpm) | 10-180 | 10-90 | 5-110 | 5-110 | 5-110 |
| Evaporation Rate (L/h) | 1.2 | 2 | 3.5 | 5 | 8 |
| Power Supply (V) | 220 | 220 | 220 | 220 | 220 |
The ex-proof rotary evaporator incorporates advanced frequency conversion and electronic speed regulation technology, ensuring stable motor operation across its full speed range. This precision control not Pre-extends equipment longevity but also significantly improves evaporation and recovery rates — a critical advantage for laboratories handling expensive or rare solvents.
The integrated bath lifting mechanism and vacuum feeding system work together to minimize the risk of rotating glass flask breakage during operation. For low boiling point evaporation applications, the receiving flask can be immersed in an ice bath to effectively reduce secondary evaporation, maximizing solvent recovery efficiency.
This rotary evaporator is specifically designed for laboratories and production facilities working with heat-sensitive materials that require gentle, controlled evaporation. Primary applications include pharmaceutical R&D, chemical synthesis, natural product extraction, environmental analysis, and academic research. The ex-proof construction makes it particularly suitable for facilities handling flammable solvents such as ethanol, methanol, acetone, and various petroleum-based extracts.
Nantong Sanjing Chemglass maintains a strong development team capable of providing comprehensive OEM and ODM services. Products can be manufactured according to specific customer requirements, with flexible minimum order quantities and competitive pricing for bulk orders. The company accepts various delivery terms including FOB, CIF, door-to-door, and air freight — tailored to the customer's logistics preference.
Through established partnerships with international express carriers including DHL, UPS, FedEx, TNT, and major shipping lines, Nantong Sanjing Chemglass ensures safe and timely delivery worldwide. All glass equipment is carefully packed to protect fragile components during transit, with air and sea shipping options available for larger orders.
Established in 2006, Nantong Sanjing Chemglass Co., Ltd. has built a reputation as a reliable manufacturer and trader specializing in the research, development, and production of chemical glass instruments. The company's comprehensive product portfolio includes glass reactors, wiped film evaporators, rotary evaporators, short-path molecular distillation devices, and chemical glass tubing. With nearly two decades of industry experience, Sanjing Chemglass serves universities, research institutes, and production facilities globally, delivering high-quality laboratory equipment backed by professional technical support.
