Pall® 4558 Acrodisc Syringe Filters with GHP Membrane, Pore Size 0.45 µm, Diameter 25 mm, Pack of 1000 . Filter Media: Glass Fiber / GH Polypro membrane (GHP, hydrophilic polypropylene)
To determine the tolerance of each membrane to chemicals, white polycarbonate, MF-Millipore, cellulose acetate, hydrophilic polypropylene and hydrophilic PTFE membrane filters that had low auto-fluorescence were mounted in chambers (37 mm monitor unit; Advantec Co. Ltd., Tokyo, Japan).
GH Polypro (GHP) Membrane Disc Filters‚ 0.45um pore size x 47mm diameter‚ 100/pk, 28143-288 Please note, due to volume, carriers have advised of potential delays. We appreciate your patience during this unprecedented time.
Sterile venting of vacuum manifolds, fermentation vessels, and sterile filtrate tanks and containers utilize PTFE 0.2 μm membranes. WTP and TE membrane ranges: WTP membranes use a polypropylene grid as the support material whereas the TE range use a randomly arranged polypropylene support material.

Description. The Poly-Fine II element is a high area, pleated all-polypropylene depth filter frequently used in a wide variety of applications for particle removal. It is a cost-effective choice for final particle removal, or for pre-filtration, including reliable protection of final membrane filters.
The second layer pair includes a second polymeric microporous membrane and a second flow channel layer oriented in a second flow direction different than the first flow direction and having a fluid inlet and a fluid outlet disposed on second opposing sides of the extraction element.
Dec 01, 2010 · The MW distributions of these two MWCO filtered microplates along with the 0.2 μm GHP (GH hydrophobic polypropylene) filter plate are shown in Fig. 2. As expected, the 0.2 μm plate allows passage of all the gel filtration standards, with equal and complete permeability of all standards except blue dextran (partially permeable).
Used flat sheet membranes must always remain wet, including during storage. Membranes that are allowed to dry will irreversibly loose water permeability. To prevent microbial growth, the membranes can be stored in a 0.5% solution of formaldehyde. Alternatively, the membranes can be stored in a 1.0% solution of sodium metabisulfite (SMBS).
Stocking a variety of filters is both expensive and inconvenient. Now you can stock just one syringe filter in the lab that is compatible with a wide range of solvents. Pall Gelman’s universal solvent filter is the GHP Acrodisc, which includes an all-purpose membrane, GH Polypro
Some membrane materials are also available sterile. Membrane filters are typically used in both liquid and air filtration. They offer accurately controlled pore size distribution with high strength and flexibility, and are suitable for a wide range of applications such as basic research, environmental testing and pharmaceutical as well as food

May 05, 1996 · This article presents our study on sterile filtration of a model protein, recombinant human growth hormone (rhGH). Scanning electron microscopy (SEM) analysis shows that 0.22-μm membranes, when used to filter the mannitol-formulated protein solution under a 0.35-bar transmembrane pressure, were plugged to a great extent.
