Prevent Blocking of Solvent Filters
Contaminated solvents or algae growth in the solvent bottle will reduce
the lifetime of the solvent filter and will influence the performance of the
module. This is especially true for aqueous solvents or phosphate buffers
(pH 4 to 7). The following suggestions will prolong lifetime of the solvent
filter and will maintain the performance of the module.
• Use a sterile, if possible amber, solvent bottle to slow down algae
growth.
• Filter solvents through filters or membranes that remove algae.
• Exchange solvents every two days or refilter.
• If the application permits add 0.0001 – 0.001 M sodium azide to the
solvent.
• Place a layer of argon on top of your solvent.
• Avoid exposure of the solvent bottle to direct sunlight.
Never use the system without solvent filter installed.
