Optimizing Performance 2

When to use Alternative Seals

The standard seals for the capillary pump can be used for most applications.

However that use normal phase solvents (for example hexane) are not suitable

for the standard seals and require a different seal when used for a longer time

in the capillary pump. In this case we recommend the use of polypropylene

seals, part number 0905-1420 (pack of 2). These seals have less abrasion

compared to the standard seals.

CAUTION

Polyethylene seals have a limited pressure range 0-200 bar. When used above 200 bar

their lifetime will be significantly reduced. DO NOT apply the seal wear in procedures

performed with the standard seals at 400 bar.
