Laboratory Filters | Solvent and Sample Filtration | Waters
Begin selecting your lab filter by determining the nature of your sample with the guidelines below: Aqueous: wwPTFE, Nylon, PVDF, and Supor PES Non Polar: CR/PTFE, wwPTFE, and MS PTFE Protein: wwPTFE and GH PVDF Ion Chromatography: Supor PES Step 2: Identify your column particle size The micron size of the particles in your column matter.
Particulate Filters/Prefilters | Pall Shop – Biotech
PreFlow™ Filter Capsules maintain Pall’s top performance with low hold up volumes, high strength and autoclavable design. Capsules are compact and can be scalable to production filters. It has a fixed pore construction and a contaminant unloading resistance. PreFlow capsules are applicable to biotechnological processing like vaccines and serums.
HPLC prep—which filter fits your chromatography sample best?
Jul 11, 2017 · You might find high particulate samples more difficult and time consuming to filter. To address this filtration challenge, stacked filter devices have multiple filter layers starting with larger pore sizes and going down to the desired pore size. This approach to sample filtration for HPLC traps large particles first and smaller particles successively (Fig 1). The device does not get clogged as easily as devices with a single membrane, making filtration and HPLC prep faster and easier.

Filtering Samples for HPLC: More Than Just Column Protection
Jan 06, 2022 · One of the precautionary steps in widespread use is sample pre-filtration, where prior to loading the sample onto the instrument it is filtered, typically using a syringe filter, to ensure it is free of any particulate matter that might damage the injector or foul the column. Particulate contamination in HPLC
In-line Filters and Mixers for HPLC | Aijiren
In-line filters available in 2.1 mm and 4.6 mm frit diameter. Different porosities from 0.2 µm to 2 µm suit different dispersion needs. Replaceable frits involve a one-time investment in the filter housing. Available for Aijiren and non-Aijiren HPLC instruments. Designed and manufactured to meet the highest quality requirements.
Filter Membranes – Sigma-Aldrich
Nylon and polyamide membranes offer broad compatibility, strength, flexibility, and hydrophilicity with low extractables, and are routinely used for the filtration of aqueous and organic solutions for use in HPLC and other analytical methods. They can exhibit high protein and small molecule binding and are not recommended for biological samples.
Hplc Filter at Thomas Scientific
This high-pressure cup-type filter can be used in fluid streams operating to 15,000 psi (103,421 kPa). The cup-shaped filter elements have a large (2.5 cm 2 ) surface area to give long operating lifetime. Mounted in screw-type adapters, they are easily removed for cleaning. Normally, backflushing.
