47-mm membrane filters designed for the Membrane Filtration technique. Membranes have superior retention characteristics and flow rate. Membranes work well for isolating and enumerating Pseudomonas sp., especially stressed organisms from process water and other fluid samples.
Hydrophobic membrane filter prevents moisture from passing through air vents and is resistant to almost all chemicals. Hydrophobic PTFE membrane filters have round disc type and roll type are both available for different applications. Operating temperature ranges from -120°C to 260°C. Inert to most aggressive solvents, including strong acids.
Disposable Pre-sterilized Suitable for 47 mm membrane filters, these 9 x 50-mm polystyrene dishes are pre-sterilized and disposable. Double rim ensures tight seal. An area of the lid is frosted for identification. Dishes are compatible with 47 mm membrane filters. Petri dishes are available with
Stainless steel construction offers excellent chemical resistance. Holders open and close easily. Filter remains undisturbed for particulate analysis. Upstream threaded vent on 47 mm holder allows release of trapped gas during liquid filtration. Convenient in-line opening and closing capability.
Filtration Membrane Discs. Thin, precut membrane rounds for high-throughput, fast filtration of liquid and gas samples. Gridded and non-gridded discs. Various materials including mixed cellulose ester, polycarbonate, PTFE, nylon, and PVDF. For air monitoring/analytical research. Sizes. Filter membranes are made in a range of diameters
These 47mm PTFEmembrane filters are an excellent choice for use with aggressive solvents, liquids and gases that can attack other membranes. They are resistant to most acids, alkalis and solvents. PTFE membranes are particularly suitable for preparing samples for HPLC analysis.
