Mobile phase filtration is performed prior to placing the solvent into the solvent reservoir. Buffered mobile phase solvents require daily filtration with a 0.2 μm filter to eliminate microbial growth that could increase the baseline. The primary concern when choosing a solvent filter is solvent compatibility with the filter material.

For example, Pall supply both a traditional ring molded 25 mm syringe filter and the Premium Syringe Filter (PSF) 25 mm syringe filter. The PSF syringe filter has a much larger effective filtration area compared with the older traditional model, 3.9 cm 2 compared to 2.8 cm 2. Therefore, this gives the PSF syringe filter a much improved

Pall Laboratory. These syringe filters offer a choice of filter media: hydrophilic nylon membrane for excellent chemical compatibility with esters, bases, and alcohols, without pre-wetting; GHP (hydrophilic polypropylene) membrane for low protein binding; and hydrophilic PVDF (polyvinylidine fluoride) membrane for.

membrane filter to prevent rapid plugging or use a 2-in-1 filter that has a built-in pre-filter in a single housing. 3. Choose the membrane type based on the solvent that you want to filter. Filter Types All filter inlets are female Luer-compatible, have inert polypropylene or polycarbonate housings and come in four diameters. 30 mm filters

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. However we are excited to announce the launch of the NEW wwPTFE universal membrane as a direct replacement for GHP filtration products.

Syringe filters, Acrodisc® GHP - VWR. Syringe filters, Acrodisc® GHP. Pall GHP Polypropylene membrane will be discontinued effective October 31st, 2019. This discontinuation affects devices including Centrifugal Devices, Syringe Filters, Filter Plates, and Membrane Filter Discs.

There are so many solvents and syringe filter/membrane materials that it can be tough to remember which combinations are safe and which are corrosive. These tables show the compatibilities between 5 materials (CA, nylon, PES, PTFE, and PVDF) and 75 common solvents (including acids, alcohols, and nitrogen solvents). Send Inquiry.

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

Universal membrane filter. The GH Polypro hydrophilic polypropylene membrane is ideal for aqueous solutions and offers maximum chemical compatibility for aggressive solvents. 96.5% protein recovery. GH Polypro membrane is a low protein binding membrane. It removes unwanted particulate from samples with high recovery of critical proteins.

Syringe Filter Housings Syringe filter housings are manufactured from solvent-resistant, low-extractable polypropylene resins specifically selected for wide compatibility with common HPLC sample matrices. Solutions at temperatures up to 100°C can be filtered using syringe filters. Syringe filters can be sterilized by autoclave at

These tables show five common syringe filter materials -- Cellulose Acetate (CA), Nylon, PES, PTFE, and PVDF -- and their compatibilities with 75 common solvents. Compatibility Tables Compatibility Grades. The tables below indicate a compatibility grade for each material/solvent combination. Safe means that the combination is confirmed compatible.

Chemical Compatibility Table CHROMAFIL® Disposable Filters This table lists the chemical compatibility of our CHROMAFIL® materials. The chemical compatibility depends on several parameters such as time, pressure and concentration. In most cases, CHROMAFIL® filters will have only short contact with a solvent. In these cases they may be used despite limited compatibility. For example, a PTFE
