The RV131 Rotary Evaporator stands out in many advantages. It comes with a large LED display and touch keys, along with an adjustable knob that helps you easily set and monitor parameters. The double-layer vertical condenser with 1500cm² cooling surface provides efficient vapor collection and sample recovery. The PID controller ensures precise temperature control.
The Rotary Evaporator, also known as rotovap, is a laboratory equipment for liquid distillation and purification. It is widely used in chemical, pharmaceutical, biotechnology industries and R&D labs to separate and concentrate samples. It usually works with Diaphragm Vacuum Pump and Recirculating Chiller as a whole system to meet the production and experimental requirements.
