I. Introduction of Rotary Evaporator:

Large capacity, large diameter rotary evaporator flask, evaporation area, the vacuum water bath, while rotating edge heating, evaporation of the solution diffusion efficiency can be used for biological, pharmaceutical, chemical, food and other small scale areas, Chinese and production. Products with recycled water multi-use vacuum pumps, diaphragm pumps, low temperature cycle (vacuum) pumps, circulating cooler, constant temperature circulator, low temperature cooling liquid circulating pump and other devices supporting component systems.

II. Features of Rotary Evaporator:

1) Teflon (PTFE) and fluorine rubber dual rotating seal, patented technology to ensure high vacuum.

2) the introduction of foreign advanced frequency control system, temperature control system, accurate and reliable.

3) a vacuum switching valve, without affecting the system vacuum distillation of the situation and the solution can be continuously collected.

4) water bath electric lift and manual lift support, easy to use.

5) PTFE discharge valve, corrosion resistance, pollution-free.
