Description

The Rotary Evaporator YG1142 // YG1145 is a high-performance instrument designed for large-scale evaporation, distillation, and solvent separation in biotechnology, pharmaceuticals, chemical engineering, and food processing industries. Equipped with a large-capacity evaporating flask, this system allows for an increased evaporation surface, optimizing efficiency and speed under vacuum conditions. Its motorized lift system, along with a stainless steel 304 water bath, ensures stable heating and smooth operation while maintaining user safety with a protective water bath jacket.

Featuring patented double sealing technology with Teflon (PTFE) and FV rubber, the YG1142 // YG1145 models guarantee superior vacuum retention, minimizing pressure loss and enhancing evaporation efficiency. The automatic switch valve allows for continuous collection without affecting the vacuum level, making it ideal for high-throughput laboratories and pilot-scale production. The vertical condenser with double coil pipes ensures efficient cooling and solvent recovery, reducing process time while improving overall performance.

With evaporation speeds ranging from 2L/h to 24.5L/h for ethanol, a precise digital temperature display, and variable rotation speeds from 20 to 140 rpm, this rotary evaporator provides unmatched reliability, efficiency, and ease of use, making it a must-have for industrial and research applications.

Market Price

The Rotary Evaporator YG1142 // YG1145 is available in the market within a price range of $4.242  to $4.400 USD, depending on the flask capacity (5L to 50L), optional accessories, and supplier. Customers can opt for a complete system, including a water circulating vacuum pump, diaphragm vacuum pump, recirculating chiller, and other necessary components. Discounts may apply for bulk purchases and institutional buyers.

Frequently Asked Questions

• What is the difference between models YG1142 and YG1145?
