Product Category Description:
For microbiological testing of water quality, food/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.
