Sterile 500 mL bottle-top filter

Each unit is a sterile PES membrane filter with a 0.22 µm pore size and a 500 mL upper capacity. The 75 mm diameter fits standard laboratory bottles. Supplied in a pack of 24, graduated for volume reference.

Replaces reusable filtration assemblies

Eliminates the need for cleaning and autoclaving between uses. The jump is worth it when sterility assurance and throughput outweigh the cost of single-use components. Not suited for workflows requiring autoclavable hardware or non-sterile pre-filtration steps.

Consistent flow under batch processing

The PES membrane maintains low protein binding during extended runs. Sterile packaging removes contamination risk across all 24 units. Graduated markings allow quick volume checks without interrupting the filtration sequence.

Questions about this item

Will the 90 mm diameter filter housing fit standard 75 mm bottle threads?

The filter has a 90 mm housing diameter and is designed for 75 mm bottle openings; verify your bottle neck size before use.

Do I need to autoclave the sterile PES membrane before first use?

The filters arrive sterile and are not autoclavable; use directly from the package without heat treatment.

When should I replace a filter from the 24 pack during a 500 mL filtration run?

Replace the filter when flow rate drops noticeably or after filtering the rated 500 mL upper capacity per unit.
