Laboratory Filtration & Filtering is a simple technique for purification of liquids and gases. The basic principle of operation is that the fluid passes through a porous structure to remove solid particulates. The pore size of the filter media determines which particles are allowed to pass. Cole Parmer UK offers a wide selection in filter media as well as housing for the filter to best suit a variety of applications in both the laboratory and process applications.
Cole Parmer UK’s range of filtration products includes filter membranes which are able to retain particles sizes from 0.1 microns, filter material including nylon to be used with alcohols and solvents along with PTFE for the most chemically aggressive solutions. Our filter housings are available in a range of styles including in-line filters, vacuum and cartridge systems. They are able to handles small volumes as low as 1ml and flow rates up to 830 LPM. When selecting a filtration system for your application consideration has to be given to :
- Filter membrane size - the size of the particle to be retained or filtered. Membranes will retain all particles equal to, and larger than their designated pore size
- the filter chemical compatibility to the membrane with the liquid or gas to be filtered. Consider the chemical resistance properties of all the parts that will contact the filtrate
- Filter housing style in terms of temperature, flow rate, throughput and sterilization needs
