Intro. 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 five common syringe filter materials -- Cellulose Acetate (CA), Nylon, PES, PTFE, and PVDF -- and their compatibilities with 75 common solvents.
Syringeless and Syringe Filters. Syringe filters and membranes for the removal of interfering materials and fine particles prior to injection; includes filters both with and without syringes; suitable for both aqueous and aqueous-organic samples; often constructed from PVDF or PTFE. Read More. Read Less. Pore Size.
Filter inlet can be connected to either a Luer slip or lock syringe. Filter outlet can accommodate a Luer slip needle or other connector. Polypropylene housing, 13mm diameter, 0.2um membrane, 100/pk. Not compatible with aqueous protein based samples, concentrated acids, dichloromethane, chloroform, hexane, acetone, MEK.
Syringe filter sizes can accommodate sample volumes from < 2 to 200 mL. For viscous or particulate laden solutions it is possible to improve throughput by using Pall’s syringe filters using a built-in prefilter. Gamma-irradiated individual blister packs ensure sterility; Ergonomic blister packs assure sterile storage, handling, and connections

Make sure that the Luer-Lok™ is matching with the syringe to prevent the filter from coming off during the filtration. Filtration. Direct the SiliCycle Syringe Filter tip into the collection vessel and apply gentle pressure onto the syringe plunger. Push the liquid sample and the air volume through the SiliCycle Syringe Filter to maximize
Syringe filters are single use, self contained, filtration devices that are typically used to remove contaminating particulate from liquids or gasses. When selecting the correct syringe filter for an application there are a number of factors to consider, these include: Filter and housing materials. Pore size.
It would be expected that syringe filters containing absolute rated membrane media would be approximately equivalent regardless of supplier for filters that have the same size, same membrane material and same pore size rating. This is not the case for syringe filters containing nominally rated media such as glass fiber or nonwoven polypropylene.
Type of Syringe Filter Membrane: Regenerated cellulose (RC) Not Recommended For: Acids: Sulfuric; Nitric (greater than 25%); Phosphoric; Hydrochloric; Alcohols: Phenol; Halogenated Hydrocarbons: Chloroform; Nitrogen: Dimethylformamide (DMF); Oxides-Ethers: Tetrahydrofuran (THF).
Sterile filtration, clarification, and particle removal. Minisart ® NML Syringe Filters provide the optimal method for clarification and sterilization of liquids, robustly removing bacteria and particles, without any impact on product quality or loss of target molecule. Superior filter areas up to 6.2 cm 2. 0.1µm to 5µm pore sizes.
A syringe filter (sometimes called a wheel filter for its wheel-like shape) is a single-use membrane based filter cartridge, to be attached with a syringe to remove impurities in liquid solutions. This pre-filtration step is vital in preventing damage to instruments (e.g. liquid chromatography, ICP, etc.).
Sep 28, 2016 · The majority of syringe filters used do not allow you to reclaim the solid. They are often used before analysis to remove any solid, undissolved, material. Other, filter holder (in-line) types allow you to regain your filter (Figure 1). Syringe filters normally use membrane type filters which have a specific particle size cut off (e.g. 0.45 μm).
Chart below shows the Chemical Compatibility of various types of syringe filters with some commonly used chemicals. All types of membrane filter products were exposed to specified chemicals/reagents for 3 days at 250C. Upshot: All products retain its Integrity after Chemical compatibility Test. O = Recommended X = Not Recommended.
CHROMAFIL disposable syringe filters are used for filtration of suspended matter from liquid samples (1–100 mL). The filter can be used for sample preparation for HPLC, GC, ICP, AAS, TOC, DOC, IR, NMR, photometry, and spectroscopy samples to filter out contaminants and extraneous particles that can affect analytical results or clog liquid pathways, frits, etc.
This group is referred to by the acronym TTHMs, which stands for total trihalomethanes. The U.S. EPA set a Maximum Contaminant Level (MCL) of .080 mg/L, or 80 parts-per-billion (ppb), for TTHMs in public water supplies. Water is sampled quarterly to form an annual average. Therefore, chloroform can exceed the MCL at any given time.
