Hawach Scientific Syringe filter are to provide fast and efficient water and organic solution filtration solutions, which are suitable for a wide range of applications in pharmaceutical, environmental, biotechnology, food, beverage, and agricultural product testing laboratories. It is made from a variety of membrane filters containing polypropylene housings, and special injection molding processes increase burst pressure and filtration speed.
Syringe filter has being used widely in laboratory, which is a kind of quick, convenient and reliable filtering tool. No need to change its membrane or clean the filter, it saves the time and trouble of so many complicated preparing jobs.
Being artistic and light, it has being widely used in sample pre-filtering, cleaning out particles and the sterile filtration of liquid or gas. Syringe filter is the preferred alternative for HPLC or GC sample filtering, usually matching with disposable syringe, with filter diameter from 4mm to 50mm, and capacity from 0.5ml to 200ml.
In HPLC analysis, the column packing particle size is small and easily blocked by impurity particles, so the sample and solvent need to be pre-filtered to remove particulate contaminants and protect the instrument.
Commonly used in environmental analysis, Ion chromatography also requires the introduction of inorganic contaminants in sample preparation. Syringe filters can be used in HPLC analysis and IC analysis to filter sample solutions as an important step in sample preparation.
Membrane material
There are so many kinds of membrane materials in the market. We can conclude them as following: Nylon, Mixed cellulose, cellulose acetate, polyether sulfone, PVDF, PTFE and glass fibre.
