Nalgene Sterile Analytical Filter Units

Certified for water quality work, the Nalgene Sterile Analytical Filter Units are disposable, preassembled, presterilized filter units and funnels include an easy-to-remove membrane for culturing or other analysis. The 47mm membranes of the Trion-free cellulose nitrate provide superior recovery and growth of microorganisms. The 0.2µm membrane is white and the 0.45µm membrane is white with gray grid. 0.45µm pore size is EPA certified.

The unit capacity has been increased to 150mL. The upper polypropylene and lower polystyrene are both graduated to the full 150mL volume for pre- and post- filtration certainty. The upper chamber twists off easily for improved retrieval of the membrane.

A stepped hose barb accepts most commonly used tubing sizes. A wider base is stable on the bench. The non-silicone gasket minimizes risk of contamination. The product also features a new easy-to-opening bag.
