PTFE high vacuum stirring bearing
Featuring high corrosion resistance and low precipitation, all mixing components have high wear resistance and will not allow debris to fall off and enter the sample
Bearings can be used with a minimum vacuum value of<1Torr and a maximum speed of 400rpm. It is recommended to use them in high vacuum environments
Use polished ultra flat glass or stainless steel stirring rods to minimize friction, and it is not recommended to use PTFE stirring rods,
According to the diameter of the mixing rod, there are three series to choose from: 10mm, 19mm and 28mm. The connection part with the reaction vessel,
You can choose standard grinding or standard threaded interface
