Replacing sealing elements 

Target group 

Personnel authorized by BÜCHI Labortechnik AG. 

Purpose 

Replacing sealing elements prevents leaks. As a result of chemical corrosion, mechanical and 

thermal stress, sealing elements in various components of the instrument can become leaky over 

time.
