1. Choose the size of filter based on the volume of sample that must be filtered. 2. Choose the porosity of the filter based on the size of potential particulates that may be present in your sample. Remember, the finer the porosity the more pressure it will take to pass sample through the filter. If you have a great deal of particulate matter, you may want to use a glass fiber filter, place a glass fiber pre-filter in front of your
Polypropylene PP Syringe Filters, 10 um, 25mm, Luer-Lock/Luer Slip, Non-sterile, 100 per pack, SF18127 Regular Price: $113.12 Price $98.37
2. Inhale the sample into the syringe, invert the syringe and clear all the residue on the top. 3. Connect the needle filter to the syringe and tighten it gently to ensure a good seal. 4. Filter the sample in the syringe and inject it into the sample bottle, then follow the steps to maximize the recovery rate.
FilTrex , " Syringe filters-Combined " , The prefilter ( PP membrane 1.0 micron ) is used with normal syringe filter to solve the problem of sample with a high load of particulate or highly viscosity solutions. The PP membrane prefilter removes coarse particles before blockage of the fine main membrane. This is the better filtration efficiency
Syringe filters are single-use, membrane-based devices used for the removal of particulate impurities from liquid and gas samples prior to analysis by methods such as HPLC, ion chromatography, gas chromatography, ICP, and dissolution testing. Proper filtration of samples improves the quality and consistency of analytical results and decreases
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. • Nominal ratings are the pore size at which a particle of defined size will be retained with an efficiency below 100% (typically 90-98%)

Filter Selection and Sizing Methods. • Select the filter material that is chemically compatible with the fluid to be filtered and that best fits your application. • Determine if you need a single-stage or multistage filtration train. For multi-stage filter systems, select the final filter first.
Oct 02, 2019 · Appropriate Pore Size: The Selection of the pore size of the syringe filter depends on the size of the particles to be filtered out from the aqueous solution. Generally, syringe filters are available in 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 sizes.
Water and acetonitrile were passed through polypropylene or PTFE syringe filters (as indicated in legend), then used 1:1 (v/v) to prepare the mobile phase for UHPLC. The system was run at 0.25 mL/min for 600 min with backpressure recorded every 50 min. DP represents total change in backpressure after 600 min.
Apr 01, 2019 · The body of the filter is important and must be considered before selecting the filter. The polypropylene body is disposable and can be used once. Polycarbonate and a stainless steel material are reusable. It depends upon the situation whether to use the disposable or the reusable ones. Filter Size is the Key. Selecting the right size of the filter increases the chances of the success of the filtration process.
manual filtration of viscous samples up to 10 mL Wide range of filter media Non-sterile 13 mm diameter Whatman GD/X disposable syringe filters are for the preparation of hard-to-filter samples. The syringe filters have a pigment-free polypropylene housing to eliminate sample contamination
