However, using syringe filters could cause loss of significant amounts of biological materials due to unwanted protein binding with the membrane or introduce unexpected interferences to the samples from the syringe filter. Therefore, low protein binding and cleanliness are important features of a syringe filter’s performance.

Setting the standard in small-volume filtration (1-200 mL), the unsurpassed consistency of Millex ® syringe filters in sample preparation has led to the development of many methods specifying their use. Featuring reduced sample loss due to minimal hold-up volumes, Millex ® syringe filters are ideal for use in a variety of applications including:
Jun 06, 2019 · Syringe filters generally are used to using membrane type filters that actually have a precise particle size cut-off. Moreover, syringe filters are available also, for the effective filtration of gases and for removing bacteria from a given sample. They are utilized in illegal drug harm reduction of course, not in the laboratory.
Syringe/Disc Filters The smaller conventional Corning® syringe disc-type filters (4, 15, 25, 26, and 28 mm diameter) are used with syringes which serves as both the fluid reservoir and the pressure source. They are 100% integrity tested. The HPLC-certified non-sterile syringe filters are available with nylon, regenerated

non-sterile syringe filters with five membrane types and two application-specific types: wwPTFE Nylon PTFE IC and Supor ® Versapor Pore sizes range from 0.2 µm to 1 µm to accommodate almost all applications. Pall Laboratory’s non-sterile syringe filters are certified for the following applications: Our 25 mm polypropylene filters come in two
A syringe filter (sometimes called a wheel filter if it has a wheel-like shape) is a single-use filter cartridge. It is attached to the end of a syringe for use. Syringe filters may have Luer lock fittings, though not universally so. The use of a needle is optional; where desired it may be fitted to the end of the syringe filter.
The hold-up volume for 25 mm syringe filters can be in excess of 1 mL and can make filtration of samples smaller than 2 mL very difficult, if not impossible, to filter. There are three ways to reduce the hold-up volume in a syringe filter. 1. Use a 13 mm syringe filter designed specifically for small volumes instead of a 25 mm filter. 2. Use a
Nalgene 25 mm diameter syringe filters (PES, PTFE, Nylon, SFCA, CA, and glass fiber prefilter) are designed to filter 10-100 ml (up to 200 ml with prefilter). Nalgene 50 mm diameter inline/syringe filters (PTFE) are designed to filter 0.2-5 L of
With low extractables and low analyte-binding membranes, Millex® syringe filters are the most convenient, highest-quality syringe filters for sensitive instrumental analyses, including gas, liquid, and ion chromatography. Wide chemical compatibility enables their use with virtually any sample composition. Request your FREE Millex® filter sample!
for the 0.45 µm syringe filter test, with Captiva Premium syringe filters. Captiva Premium nylon 0.2 µm and regenerated cellulose 0.2 µm syringe filters were used to assess filtration impact on sub-2 µm column life, and nylon 0.45 µm syringe filters were used to test filtration impact on the life of superficially porous columns.

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).
