• Always use the appropriate solvent line filters as recommended by
Thermo Fisher Scientific. Check the filter frits for permeability at
regular intervals and replace them as necessary.
•
The pump is shipped with UHMW-PE piston seals. Using
tetrahydrofuran, ketones, or ammonium hydroxide as solvents can
cause swelling and damage the seals.
•
For best seal performance, do not recycle or recirculate solvents.
Avoid using methanol from aluminum reservoirs.
•
To reduce the growth of algae, consider using amber glassware or
using appropriate additives, for example, formic acid.
• After operation, flush out buffers and solutions that form peroxides.
•
Never leave buffers, salt solutions, or aggressive solvents in the
system for a longer period without flow.
•
Note the special properties of the solvents, such as viscosity, boiling
point, or UV absorption.
