View Nylon Membrane Filters View Nylon Syringe Filters. Polypropylene (PP) Polypropylene membranes are a hydrophobic membrane that exhibit a wide range of chemical compatibility to organic solvents. PP membranes are a good choice for filtration of HPLC samples when performing protein analysis by chromatography.
For over 140 years Sartorius has been using science to create solutions for our customers. The Sartorius Lab Filtration portfolio, whether it is simple filter papers or microporous membranes, to the latest innovation in filtration devices, ultrafiltration units, or protein or DNA purification devices each demonstrates Sartorius’ commitment to using the best in science and engineering design
2. Decide an appropriate pore size. The pore size of a filter, stated in microns (aka micrometers or µm), is determined by the diameter of particles retained by the filter or by a bubble point test. Fun fact: Due to viscosity differences, a 0.2 micron pore size rated membrane in liquid can retain up to 0.02 micron particles in air. What size
compatibility with the liquid you want to filter by performing a trial filtration run before you start your actual filtration.

Oct 31, 2016 · GD/XP Syringe Filters. Using a similar filter stack, the GD/XP range are designed for samples which need inorganic ion analysis, or where low protein binding is required – for example in trace metal analysis, or HPLC sample preparations. The GD/XP range have a 3 layer filter system – first a 20 µm polypropylene filter, then a 5 µm
Nov 15, 2014 · Please refer to the various manufacturers data sheets to select an appropriate syringe filter with: (1) a low hold-up volume; (2) large enough size for the volume of sample; (3) which is chemically compatible with the solution and material you are going to inject through it and (4) lowest protein binding affinity (if applicable).

Syringe filters for ion chromatography are available in 0.05 µm, 0.10 µm, 0.22 µm, 0.45 µm, 0.70 µm, 0.80 µm, 1 µm, 3 µm, 5 µm, and 10 µm pore sizes. If you need to extend the life of the filter or allow for increased flow during filter life, choose a syringe filter with a prefilter. Diameter
™ Syringe Filters Daily: • Less system downtime • More consistent, reproducible results • Increased column lifetime • Rapid filtration of HPLC and GC samples prior to analysis Quality filtration products from Phenomenex offer a convenien t and inexpensive way to clarify all your samples - for peace of mind and improved analytical results.
Polypropylene (PP) Syringe Filters are designed to filter gas and organic solvent-based samples in a wide array of analytical and research applications. These units are recommended for ion chromatography, HPLC sample preparation and critical low detection levels 230 nm.
Accurate quality control: The integrity of the syringe filters is tested to ensure adequate sealing and sealing of the filter to eliminate any possible filter by-pass. Accurate Labeling: Each filter is labeled with the specific filter material and pore size for easy identification even if the syringe filter is not in the original packaging.

tors. Grey polypropylene cap center rotates freely, allowing the bottle to be unscrewed with-out the need to disconnect the tubing. The cap is ideal for use with soft elastic tubing that has an inner diameter of 6 – 9 mm silicone tubing. An optional venting connector is available with, or without a syringe filter.
