• 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, (Flush Filter in context menu figure)
• Exchange the filter frit on a regular basis. ( Frit 0.3 μm for inline filter, 5/pk
