Hydrophilic membrane compatible with a wide variety of solvents. Useful for a wide range of applications, including aggressive and non-aggressive solvent-based mobile phase. 20 Products In Family $ 686.88 - $ 2,952.72
Millex® syringe filters are available in sterile and nonsterile formats, offered in many membrane and housing options to enable compatibility with multiple solvents and sample types for applications including HPLC, UHPLC, and dissolution testing.
Pall Minispike Acrodisc Syringe Filters, Pall Life Sciences Ghp Membrane is a reliable and dependable addition to the Pall Filters family of products. Combining top-notch and uncompromising quality with an affordable price, the Pall Minispike Acrodisc Syringe Filters, Pall Life Sciences Ghp Membrane 4567/ 28139-554 can fulfill your laboratory needs while still offering a great value for the money.
However we are excited to announce the launch of the NEW wwPTFE universal membrane as a direct replacement for GHP filtration products. Pall’s next generation of universally chemically compatible membrane, our water wettable polytetrafluoroethylene (wwPTFE) membrane, yielded significant performance advantages compared to GHP when extractables, binding, column life and chemical compatibility were evaluated.
Stock sample solutions prepared in 50:50 0.1 N HCl/ethanol were filtered through three, 0.2-μm, syringe filters. As shown in Table 2, filtration through the GHP-membrane syringe recovered the memantine HCl from the tablet formulation most effectively.
Sep 03, 2013 · GHP hydrophilic polypropylene (GH Polypro) is ideal for chemical compatibility, fast flow rates, low protein binding, and low levels of UV-absorbing extractables. Glass fiber prefilters allow for quick and easy filtration for difficult-to-filter aqueous solutions. PVDF membranes have excellent compatibility with aggressive acids and alcohols.
The wwPTFE membrane is ideal for sample preparation and solvent filtration. Extend column life up to 52x. Improve result quality with up to 24% less filter extractables and lower adsorption. Use one membrane filter type for all your sample preparation applications. Hydrophilic wwPTFE membrane also available in two LCMS-certified configurations.
GHP Membrane All purpose, universal, hydrophilic polypropylene membrane with maximum chemical compatibility for harsh solutions Special Features: • HPLC certified • Versatile design fits most HPLC bottles, flasks and containers. Eliminates the added steps of washing flasks and transferring mobile phase
GH Polypro (GHP) Membrane Disc Filters Hydrophilic polypropylene membrane with maximum chemical compatibility when filtering both aqueous solutions and aggressive solvents. High recovery of critical proteinaceous samples due to low protein binding. HPLC certified. 47mm diameter. Pore size: 0.2um.
RC also has a broad solvent compatibility. Together with PTFE, RC is a useful general-purpose option to have on-hand. Extractables are a common symptom of membrane-sample incompatibility and affect sensitive downstream analytical techniques, such as ultra-high-performance liquid chromatography (UHPLC) and high-performance liquid chromatography

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 (GHP), that is effective for harsh aqueous samples and for aggressive organic solvent-based solutions.
Stock sample solutions were prepared by dissolving tablets containing 10 mg of memantine HCl in 50:50 0.1 N HCl/ethanol,* to a concentration of 1.0 mg/mL. The solutions were sonicated and centrifuged, at 3500 rpm, for 30 minutes. Finally, the solutions were filtered through 0.2-µm GHP membrane syringe
