Yes. Our membranes can withstand 100’s of psi of trans-membrane pressure, can tolerate high radii of curvature, are highly flexible, and device fabrication processes can be performed by skilled technicians using hand tools outside of a clean room environment. Also, our membranes are probably more affordable than you think.

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. Syringe filters are attached to the end of a syringe to remove particles from a sample prior to analysis. Filtering liquids, the single-use devices force liquids through the filter either
3. High temperature, generally about 280 degrees in normal use. 4. Chemical stability, acid corrosion, with antioxidant properties. 5. No particles off, do not make the liquid form a secondary pollution, in line with food hygiene and pharmaceutical GHP requirements. 6. Mechanical properties, and can be filter press filter, simple operation. 7.
filters (from all manufacturers) and the PVDF and GHP filters from Pall. These did not meet the criterion of a 95% drug recovery in the filtrate. Figure 1B displays the recovery of acetylsalicylic acid after the first 2 mL of media was discarded. When 2 mL was discarded before analysis, the recovery improved, and all filters in all buffer media
Filters are molded in the polypropylene housings, providing a reliable seal without the use of adhesives Female luer-lock inlet and male luer slip outlet Color coded by membrane type for easy identification, and membrane material and pore size are printed on the housing Available individually packed in peel-to-open paper/plastic blister packs Also available bulk packed in PVDF, PES, PTFE, and
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.
Polycarbonate Track-Etched Membrane Filters / 0.2 µm / 25 mm Discs. These hydrophilic polycarbonate track-etched filters are manufactured from high quality polycarbonate film using track-etch technology. They have a sharply defined pore size of 0.2 µm with a pore density of 5.0E+08 cm². Pack of 100 white 25 mm discs that have a high chemical
Syringe filters are single-use filtration devices that are made up of a membrane, or combination of membranes, placed inside molded housing. The connections on the device are commonly Luer lock or Luer slip and enable a quick connection to syringes, that are used to pass the liquid sample through the filter.
This syringe filter is made with GHP (hydrophilic polypropylene) membrane for low protein binding and features a polypropylene housing with female Luer-lock inlet and standard male slip Luer outlet connections. The membrane is HPLC certified for low levels of UV-absorbing extractables. Membrane: GHP Membrane. Pore Size: 0.45 µm. Typical hold-up volume: \\<100µL. Pall Life Sciences #: 4560.
General description. These offer high quality filtration for analytical samples. Certified for HPLC to ensure low extractables. Available in a broad range of membranes to meet sample compatibility requirements. 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.
– Filter (0.2 µm filter membrane) – Keep concentrated stock solutions to prepare from – Do not top off buffers. (Can promote microbial growth) – 48 hour changing Filters – We generally recommend o hydrophilic Teflon filters (PTFE) o GHP filters for aqueous solutions – Filtering organic and aqueous solutions through Nylon filters
