Nalgene Sterile Analytical Filter Units
Thermo Scientific Nalgene Sterile Analytical Filter Units are disposable, preassembled, presterilized filter units and funnels include easy to remove membranes for culturing or other analyses. The 47 mm membranes of Triton-free cellulose nitrate provide superior recovery and growth of microorganisms. The 0.2 µm membrane is white; 0.45 µm membrane is white with gray grid. 0.45 µm pore size is EPA certified.
The unit capacity has been increased 150 mL. The upper polypropylene and lower polystyrene are both graduated to the full 150 mL volume for pre and post filtration certainty. The upper 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 new easy-opening bag.
