20L Rotary Evaporator
Purposes and features:
NR-series large rotary evaporator is mainly used in the small-scale test, pilot-scale test and production in biological, pharmaceutical, chemical, food and other fields. As with large capacity and large-diameter rotary evaporating flask, when it is placed in a water bath, along with the simultaneous performing of rotating and heating, it allows the solution spreading and evaporating rapidly. What’s more, the product may be fitted with the multi-purpose water circulating vacuum pump, diaphragm vacuum pump, low-temperature circulating (vacuum) pump, circulating cooler, constant-temperature circulator, low-temperature cooling liquid circulating pump and so on to form a system device.
1.Teflon(PTFE) and fluororubber dual spin seal, patented technology to ensure the high vacuum.
2.Accurate and reliable temperature control system,.
3.On the premise of not affecting the vacuum and solution distillation, continuous receiving allowable.
4.PTFE emptying valve, corrosion-resistant without any pollution.
5.Including two types: regular type and explosion-proof type, which can be adopted based on the experimental environment.
