Low protein binding of GH Polypro membrane provides high recovery of critical proteinaceous samples. HPLC certi-. fied to assure that the filter will not add artifacts to analysis. Diameter.
Protein binding and sample extractables In addition to resistance and clogging, membrane-sample compatibility affects the composition of the filtrate. An incompatibility here can lead to sample solutes unexpectedly being retained by the filter (protein binding) or unwanted solutes being released into a sample (extractables) from the filter
The 25 mm Acrodisc is recommended for sample volumes from 5 to 100 mL. The 13 mm size is recommended for samples under 10 mL in volume. The 4 mm size is for samples under 2 mL. PP housing with Luer fittings. GHP - hydrophilic PP membrane suitable for both aqueous and organic samples. GXF - multi-layered glass fiber prefilter.
removed prior to use by filtering a small amount of warm purified water through the membrane or filter unit. Surfactant-free cellulose acetate membranes with very low levels of extractables are available on some Corning® syringe filters. Cellulose nitrate (CN) membranes are recommended for filtering solutions where protein binding is not a
The 0.45 m Acrodisc syringe filter with GHP (hydrophilic polypropylene) membrane feature low protein binding. The GHP membrane is also HPLC certified for low levels of UV-absorbing extractables. This product is sold in a pack of 50 filters.
and low non-specific protein and nucleic acid binding. Add versatility – Available in various membrane types including low-binding Bio-Inert ® (modified nylon), Supor ® (polyethersulfone), and GHP (polypropylene) membranes, as well as Omega™ (modified polyethersulfone) ultrafiltration membrane in a variety of MWCOs.
Acrodisc® Syringe Filters with GHP Membrane, Pall Laboratory. Pall GHP Polypropylene membrane will be discontinued effective October 31st, 2019. This discontinuation affects devices including syringe filters, filter plates, centrifugal devices and membrane filter discs. The GHP membrane used in Pall Laboratory Acrodisc® syringe filters, centrifugal devices and Acroprep™ filter plates will be discontinued due to the rationalization of a key material from our supplier.
Acrodisc 25mm Premium Syringe Filter GxF borosilicate glass prefilter. Polypropylene housing. 0.45um GHP hydrophilic polypropylene membrane for chemical compatibility fast flow rates low protein binding low levels of UV-absorbing extractables. Filtration area: 3.9cm2. Hold-up volume: \125uL.
The WWPTFE (water wettable polytetrafluoroethylene) membrane can be used with both organic and aqueous solvents. When coupled with a polyethylene housing, the membrane offers excellent chemical resistance. Low protein binding. Get accurate and confident quantitative results. There is minimal protein adsorption with the MS wwPTFE syringe filters.
