Hydrophilic PTFE sample prep syringe filters have excellent chemical resistance, are able to be used with aqueous solutions, and are perfect for use with aggressive solvents and with HPLC sample prep.Syringe filters are attached to the end of a syringe to
Usage of a PTFE Syringe Filter can be done for aggressive solvents, aerosol sampling, degassing solvents, venting application and to filter organic- based HPLC. Syringe Filter comes with a variety of different filter covering and has a wide chemical compatibility and
Membrane Type (PTFE, GHP, PVDF, Nylon) — Typically, the first step in selecting a suitable filter is to choose a membrane that is chemically compatible with the sample (see chart opposite). For aqueous samples, it is preferable to use a hydrophilic membrane (GHP, PVDF or Nylon) versus a hydrophobic membrane (PTFE).
filter, clogging of the membrane filter is prevented and sample clean up is optimized.Outlet connection is luer lock. AF0-8515-12 6 100/Pk AF0-8515-52 6 500/Pk Above syringe filters are non-sterile. Housing is made of medical-grade polypropylene (PP) and offer
The effect of analyte concentration on binding. Strategies to minimize analyte binding to syringe filters. High-pressure liquid chromatography (HPLC) analysis is very commonly used in various industries for quantitation of analytes. However, such quantitation can be affected by analyte binding to syringe filters.
Guide to selecting the right syringe filters. 1. Choose membrane type. Nylon - Broad solvent compatibility, Aqueous and organic materials. PTFE - Ideal for HPLC, UHPLC
16/2/2019 · The texture of syringe filters include Nylon, PVDF, PTFE, MCE, CA, Glass Fiber, PP, PES. When choosing the texture of syringe filters, we need to consider pore diameter, chemical resistance (if can resist all carrier oils and solvents), oil-based or water-based solution, and etc. Here are the pore diameter of common syringe filters.

extractables, samples of the entire HPLC Acrodisc syringe filter line are evaluated prior to release. Mass Spectrometry Certified for Low Extractables To ensure low levels of extractables, Pall certifies that all lots of water wettable polytetrafluoroethylene (WWPTFE),
You must choose the pore size according to the sample passing through the filters. The filter with pore size of 0.2 micron is perfect for sterile venting. For transducers protection in gas or air filtration, you may opt for filters with pore sizes ranging from 1.0 to 0.45 micron.
And what is important in choosing the right inline filter? The in-line filter can be positioned at various locations of the HPLC system. If the inline filter is installed between the pump and the injector, particles and impurities are removed from the eluent.
HPLC Syringe Filters are typically used for clarification, sterile filtration, sample preparation, sterile venting and medical applications. All the syringe filters are certified by HPLC Extractable Test. Product Information and Parameter
CA (Cellulose Acetate) combine high flow rates and thermal stability with very low absorption characteristics. Especially 0.22um pore size CA Sterile Syringe Filter excellently suited for sterilization aqueous solutions, buffers, sera and media. Low protein binding to minimize sample loss.
PTFE, polyvinylidene difluoride (PVDF), and RC are compatible with a wide range of solvents commonly used in HPLC while remaining low in extractables. Compatibility tables list material resistance to common solvents, making them useful for quick reference.
