Labfil Syringe Filters. Labfil syringe filters use PES (Polyethersulphone) with very wide chemical compatibility and excellent flow rates. These syringe filters have proved themselves in applications such as sample clarification prior to HPLC, IC or ICP analysis. They come mainly in 0.45 μm pore size, 30 mm diameter ,and in packs of 50 and 500.
Chemical compatibility is a critical consideration when selecting the proper sample prep syringe filter for your application. This chart outlines the chemical compatibility of the most common syringe filters. The contact time was 24 hours at 20°C.

Laboratory filter membranes, also known as cut disc membranes, are used in conjunction with filter holders and other hardware in a variety of applications including prefiltration, solvent filtration, sample clarification, sterilizing filtration, air monitoring, particle collection and analysis, and other biological and environmental applications.
In addition, many Acrodisc Syringe Filters offer the option of a minispike outlet, rather than the traditional male luer outlet. The minispike outlet, available on 13 mm PTFE, Nylon, GH Polypro, and PVDF Acrodisc Syringe Filters, allows for easy dispensing into autosampler vials.
For non-aqueous samples, screening PTFE and regenerated cellulose, assuming that chemical compatibility is adequate for the sample solvent, would be a good idea. Syringe Filter Finder 3-step tool designed to help you find the appropriate syringe filter to help you successfully remove particulates from your sample matrix.
Acrodisc ® 25 mm Syringe Filters These syringe filters offer a choice of filter media. Hydrophobic PTFE membrane for exceptional chemical and temperature compatibility and hydrophilic PVDF (polyvinylidine fluoride) membrane for use in aqueous and nonaggressive, solvent-based mobile phases.
EconoClear syringe filters use PES, Polyethersulfone, with its very wide chemical compatibility and excellent flow rates. These syringe filters have proved themselves in applications such as sample clarification prior to HPLC, IC or ICP analysis. They come mainly in 0.45 pore sizes, 28mm diameter, and in packs of 100 and 500.
Filters. Our range of membrane, syringe, and capsule filters represent the industry’s highest quality manufacturing standards, product performance, and application support for laboratory-scale filtration. Reduce process times, increase analytical efficiency and produce consistent, measurable results today with our filtration devices.
Membranes Designed for the StringentRequirements of Mobile Phase Filtration. Membranes are identical in composition and quality to those used in Pall’s HPLC-certified Acrodisc ® syringe filters. HPLC certification assures that the filters will not add artifacts to your analysis. GH Polypro membrane is the best choice for filtering mobile phases.
Spectrum Chemical carries a full line of analytical-grade laboratory chemicals for reliable, precise results, in analysis, research and development, bench-scale chemistry or process scale-up. Whether you're looking for solvents, ACS grade chemical reagents, analytical reference standards or chromatography supplies, Spectrum has it.
A filter for HPLC applications is designed to increase accuracy by removing unwanted particles. However, the wrong filter can be a source of contaminants in the form of extractables that elute into the sample from the filter device. These undesired artifacts can jeopardize analytical results.
