Ideal for microbiological testing of water quality, food and beverages, raw material, sterility, and finished product quality. Use in vacuum manifolds and filter flasks.

Each disposable, sterile filter funnel consists of a polypropylene upper chamber, a high-impact polystyrene collar, and a cellulose nitrate membrane. Graduated upper chamber separates easily from the collar for easy access to the membrane. Funnel adapters allow use with No. 8 stoppers; six adapters are included with each case. The 0.45µm pore size membranes are certified for water quality work including coliform analysis. Membrane diameter: 47mm.

Note: For lab use only. Not for in vitro diagnosis or parenterals.
