PTFE (Polytetrafluoroethylene) disk filters are hydrophobic and chemically resistant to all solvents, acids, and bases. They are ideal for use in equipment protection as they block water vapor. PTFE Disk filters are commonly used to assist in protection of work areas from airborne pathogens and hazardous vacuum pump exhaust or venting. They can also be used for filtering aggressive solvents in volumes beyond standard syringe filter capacity, venting carboys and filling culture vessels and CO2 incubators, and filtration applications that involve bacterial retention.

Nylon disk filters are suitable for bacterial and particulate removal applications, HPLC solvent filtration, drug Filtration and protein and lateral flow assays. Nylon disk filters can be used with a variety of biological preparations and are especially utilized where other membranes become difficult to use. Nylon is a very durable membrane material.

Cellulose Acetate (CA) disk filters are great for filtering aqueous and alcoholic media, especially at high temperatures. Cellulose Acetate disk filters are exceptionally low when it comes to protein binding, they provide extremely high throughputs and require less filter changes when filtering high protein solutions. They are ideal for protein and enzyme filtration, and biological fluid filtration.

Glass Fiber disk filters are commonly used as pre filters in many filtration devices and for filtration of viscous or otherwise hard-to-filter samples with high solids content. These hydrophilic membranes feature high-dirt loading capacity, and excellent compatibility with organic solvents and acids. They are an excellent filter for use in environmental, biotechnology, food/beverage, agricultural and many other industries..
