Filters
Filters are essential in research laboratories and many other industries for removing particulates and creating environments conducive to a wide array of experiments and procedures. The devices come in different forms including in-line filters, paper discs, small capsules, and large ventilation panels. Filters also purify and concentrate the liquids and gases required for testing. For air, this means removing pollution, moisture, and solid airborne particulates; for liquids, this means removing impurities and small contaminants.

Acrodisc® Syringe Filters, Glass Fiber, Pall® Life Sciences
Supplier: Cytiva
For prefiltering heavily contaminated aqueous or solvent based samples. Filters are made of 100% binder-free borosilicate glass fiber. Hydrophilic nylon membrane has excellent chemical compatibility with esters, bases, and alcohols and does not require prewetting. GHP (hydrophilic polypropylene) membrane is low protein binding. Both nylon and GHP membrane filters include a glass fiber prefilter layer, as well as being HPLC certified for low UV-absorbing extractables. The regular glass fiber membrane has very low extractables. Polypropylene housing. Female Luer-lock inlet and male slip Luer outlet.
