Troubleshooting
We provide two kinds of pump tubing: silicone rubber (Standard Tubing Pack) and Viton®
(Acid Tubing Pack). Silicone rubber is suitable for most aqueous solutions and is
recommended when the pump will be used for prolonged periods. Viton withstands many
strong acids, alkalis and organic solvents, which corrode silicone rubber.
Use the table below to verify that your chemicals are compatible with the provided tubing, or
other tubing that is compatible and meets our specifications.
The table is only a general guide. Each rating is based on ideal testing conditions used by
tubing manufacturers. Temperature, length of service, chemical concentration, etc. can affect
chemical resistance. Test the tubing under your experimental conditions.
