Optional Inline Filter

The pump can be equipped with an additional inline filter (Inline Filter
Assembly (5067-5407)) with a nominal filter pore size of 0.3 μL.
Advantages of the inline filter:
• Very small internal volume
• Specified for working at high pressures
• Possibility of back-flushing the filter
Using the inline filter is recommended:
• to protect the downstream system from blockages,
• for solvent combinations that can form precipitation after mixing,
• for applications running with buffers.
General hints for effective usage of the inline filter:
• filter solvents before usage,
• follow best practices,
• back-flush the filter weekly,
• exchange the filter frit on a regular basis.
