Thermo Scientific Nalgene® Reusable Filter Holders are constructed of polysulfone (PSF) with a silicone O-ring and a polypropylene vacuum adapter, screws tightly onto bottles with 47 mm to 50mm neck heads. The filter is strong and transparent, and the silicone O-ring seals the membrane and prevents bypass of liquids.
This filter is helpful in field study, designed for filtrating liquids or gases and detecting microbial contamination in production lines.
The filter accepts 1/4-in. to 5/16-in. (6- to 8-mm) I.D. vacuum tubing (along with syringe filters), while two side arms connect to vacuum line. The filter is also fully autoclavable—the tubing adapter can be stuffed with cotton for sterile venting during autoclaving.
