Using an appropriate filter designed for these small volumes will minimize holdup volume and improve your sample recovery. Our 4 mm diameter Millex® syringe filters and Ultrafree®-MC centrifugal filters will efficiently process small volume samples with holdup volumes as low as 5 µL.
Syringe filters, Minisart® RC. Description: Minisart® RC (regenerated cellulose) is optimised for aqueous liquids and solvents with a pH of 3 - 14 and is stable against DMSO. This product is no longer available. Alternatives may be available by searching with the VWR Catalog Number listed above.
S-LAB syringe filters provide fast and efficient filtration of aqueous and organic solutions and are available in all the major membranes (nylon, hydrophilic & hydrophobic PTFE, regenerated cellulose (RC), PES, MCE, and PVDF) and in three different size formats (4 mm, 13mm, and 25 mm).
The right sample preparation solution can save you time and solvent, reduce repetitive functions, and provide consistency and accuracy of results. You’ll find the right solution among our broad selection of sample preparation consumables. Our most recent innovations include the SMART Digest kits for fast, highly reproducible protein digestion
HPF Millex® filters for high particulate filtration Sample volume: 10-100 mL Features: Includes two different media – a graduated glass fiber prefilter and a membrane filter to provide two to four times greater throughput than syringe filters without prefilters. For manual or automated use.
Syringe Filters Single Layer Filters: Single membrane, commonly used, highly cost-effective; newly developed Ф33 mm Syringe Filters, with pore sizes of 0.22 μm and 0.45 μm are in stock. Double Layer Filters: A prefi lter before the main membrane, which would avoid the damage to the soft main membrane from larger
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!
Whatman SPARTAN syringe filters from Cytiva provide reproducible filtration for ultra-high performance liquid chromatography (UHPLC) and high performance liquid chromatography (HPLC) sample preparation and analysis. Excellent chemical resistance to common aqueous and organic solvents, so recommended for HPLC method sample preparation. See full list on cytivalifesciences.com
Syringe filters with different pore size ratings are suitable for different applications. For example, syringe filters containing 0.45 μm are typically used for HPLC sample preparation and 0.2 μm is used for UHPLC. In life science applications 0.1 and 0.2 µm pore sizes provide sterilization of buffers, culture media, and additives.
syringe filters with 0.2 µm pore size, and Mini-UniPrep™ syringeless filters with 0.2 µm pore size. Bovine serum albumin (BSA) was selected as the typical protein. A 5 mg/mL stock was prepared in PBS buffer, pH 7.4, then prefiltered using a SPARTAN 30 mm, 0.2 µm syringe filter. The stock was diluted with PBS to
SPARTAN syringe filters with 0.2 and 0.45 µm pore sizes, 25 mm diameter Whatman GD/X™ syringe filters with 0.2 µm pore size, and Mini-UniPrep™ syringeless filters with 0.2 µm pore size. Bovine serum albumin (BSA) was selected as the typical protein. A 5 mg/mL stock was
Syringe filter is a cost-effective way to improve the quality of HPLC analysis,improve consistency,extend column life and reduce maintenance.By removing particulates before the sample enters the column,syringe filter allow unimpeded flow.Without particulates to create obstructions,your column will work more efficiently and last longer.
Pall’s IC Acrodisc syringe filters have been optimized for ion chromatography sample preparation applications. Available in both 13 mm and 25 mm formats, the syringe filters contain a hydrophilic polyethersulfone (PES) membrane that has undergone several washing steps ensuring the product has low conductivity detectable extractables.
Oct 13, 2020 · A 2 mL sample of the final solution was filtered through a 0.2-µm syringe filter for HPLC analysis. Preparation of System Suitability Solution System suitability solution was prepared by adding measured volumes of ORA-Plus (0.125 mL) and ORA-Sweet (0.25 mL) to 1 mL of TG reference standard stock solution (20 mg/mL) and the volume was made up
