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 0.0001-0.001M sodium azide to the solvent.

• Place a layer of argon on top of your solvent.

• Avoid exposure of the solvent bottle to direct sunlight.

NOTE

Never use the system without solvent filter installed.
