The support base has a coarse-porosity glass frit and an integral vacuum connection, located above the drip tip to prevent contamination of the vacuum line with filtrate droplets. Each apparatus includes a funnel, an anodized aluminum clamp, a 47 mm fritted glass support base, and a filtration flask.
The filters can be installed in compact, automated, or modular units. These strainers can be used as separators between stacked discs in a single filter holder during serial filtration. Membrane filters are virtually inert to chemical and biological agents, ensuring stability when filtering concentrated acids, alkalis, or oxidizers.
The membrane material in the filter must provide sufficient surface area (effective filtration area) or open space to accommodate the air flow required by the system. Pall offer devices with effective filtration areas (EFAs) that range from 7.5 to 300 cm 2 , allowing users to select the most appropriate vent size for their application.
The filter housing materials, as well as the filter membrane must be compatible with the solutions being filters. Polystyrene (PS) is used in the filter funnels and storage bottles for the Corning plastic vacuum filters. This plastic polymer should only be used in filtering and storing nonaggressive aqueous solutions and biological fluids.
Our range of membrane, syringe, and capsule filters represent the industry’s highest quality manufacturing standards, product performance, and application support for laboratory-scale filtration. Reduce process times, increase analytical efficiency and produce consistent, measurable results today with our filtration devices.

The Autofil™ laboratory filtration system is a disposable, sterile, vacuum operated bottle-top filter system used for the preparation of buffers, tissue culture media, microbiological media and other biological fluids. Autofil™ filters are available either as a complete system or as a stand-alone bottle-top filter funnel. Read More
Easy-to-use vials offer fast sample filtration and require only a squeeze of your fingers. Color-coded caps allow easy identification of 0.2 μm or 0.45 μm membranes in PVDF, PTFE, PES, or nylon. Preslit PTFE/silicone caps help eliminate broken autosampler needles and cored septa.
The main application of these membrane filters ist the filtration of air, gases and chemicals. PTFE membrane filters have an excellent chemical compatibility (pH 1 to 14), so that they are also used for the filtration of solvents and acids, to which other filter types are not resistant.

Air and gas sterilization* make use of the hydrophobic characteristics of PTFE membrane filters and their ability to stop aqueous aerosols. Pore sizes of 0.2 µm and 0.5 µm are typically used. Sterile* venting of vacuum manifolds, fermentation vessels, and filtrate tanks and containers utilize PTFE 0.2 µm membranes.
PTFE microporous membrane pleated filter element is made of natural hydrophobic polytetrafluoroethylene (PTFE) membrane and polypropylene material parts by advanced hot-melt sealing technology in a controlled Class-100 clean environment without any adhesive and surfactant, and meets the technical requirements of the national standard of the people's Republic of China GB / T 34244-2017 filter
