PALL 4203 Filter Funnel 25mm, 200ml, Polysulfone (1/pk)

The Pall 4203 filter funnel is designed for vacuum filtration and liquid clarification using 25 mm membrane filters. It allows researchers to separate particles or microorganisms from liquid samples efficiently during laboratory analysis or sample preparation.

This funnel is designed to hold 25 mm diameter membrane filters, making it suitable for many laboratory filtration tasks such as environmental testing, microbiology studies, and particle contamination analysis.

Yes. The funnel is made from durable polysulfone, which can be autoclaved at approximately 121–123 °C for sterilization, allowing it to be reused in many laboratory workflows.

Polysulfone filter funnels offer several benefits, including excellent chemical resistance, transparency for visual monitoring, and greater durability than glass, while typically costing less than stainless steel filtration hardware.

The funnel has a 200 mL capacity, allowing users to process moderate sample volumes during filtration while maintaining compatibility with standard laboratory vacuum filtration setups.
