Frits and filters made of a new polymer are especially useful for biochromatography applications such as the separation of proteins, peptides and nucleic acids
Biotech announces the availability of HPLC and IC frits and filters made from Pat, a new polymeric material which combines the strength of Peek and the inertness of Teflon.
This material is specifically designed to eliminate the corrosion and mobile phase contamination that is frequently experienced when metallic frits and filters are used in HPLC or IC.
Pat frits and filters are especially useful for biochromatography applications such as the separation of proteins, peptides and nucleic acids as these compounds will not bind to them.
Another important application is ion chromatography, where mobile phases that corrode stainless steel, such as strong buffers and salt solutions, are commonly used.
Pat frits and filters contain no metals or extractable materials and can be used with any HPLC or IC column or mobile phase, even those that can attack stainless steel.
Filters and frits made from Pat provide exceptional mechanical stability and high temperature stability.
They can be autoclaved and sterilised.
If desired, Pat frits and filters can be provided with a solid Peek ring for added strength.
Frits are available in a broad range of sizes ranging from 0.062" to 0.750" in diameter and 0.8 and 1.59mm thick with 5um and 10um pores.
