620 6. Distillation, separation, filtration Distillation, synthesis/KPG stirrer and bearings-Dropping Funnels GENERAL CATALOGUE EDITION 20 E & OE. Stirrer Bearings, PTFE The sealing rings on these bearings ensure a perfect sealing. The ground joint no longer sticks, the danger of breaking is reduced and the cone can be removed easily from the socket. A special gasket made of PTFE and an FPM o-ring which is compressed by a GL screw cap provide a good sealing of the stirrer shaft. This gasket can be exchanged after wearing. Suitable for vacuum, perfect bearing for stainless steel, glass and BOLA Stirrer Shafts. 1 BOLA For diam. stirring rod Overall length Neck thread Cone PK Cat.
