Pall Magnetic Filter Funnel 300mL, 47mm - 1/Pk - 4242-N
Quality controls spanning raw membrane casting through final device verification ensure consistent retention performance across Pall production lots. Filter funnels seat a membrane disc across the base of the funnel so a full sample passes through in one contained step. A secure seal holds the membrane edge to prevent sample bypass and routes the full sample through the membrane into the collection vessel. Across routine monitoring programs, that clean separation supports defensible colony counts and traceable particulate determinations.
Key Characteristics
- Connects to a side-arm vacuum flask or filtration manifold
- Seats and seals a flat membrane disc for leak-free dead-end filtration
- Autoclavable construction supports aseptic technique between samples
- Durable, chemically resistant body stands up to repeated reuse
- Secure seal protects the membrane from twisting and tearing during setup
Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. General-purpose aqueous filtration supports the sample types you handle every day from reagent and buffer preparation through routine sample clarification.
