Professional teflon hplc filters for analysis

Whatman® merane filters PTFE pore size 0.2 μm, diam. 47

This includes the important requirement in HPLC analysis for sample filtration where any solid particles can cause permanent damage to the column. The 0.5 μm pore size is normally used. Air and gas sterilization make use of the hydrophobic characteristics of PTFE meranes and their ability to stop aqueous aerosols.

PP meranes are a good choice for filtration of HPLC samples when performing protein analysis by chromatography. In addition to being highly solvent resistant, these meranes are low non-specific adsorbing meranes, which results in maximum protein recovery for critical analysis. PP meranes are also well suited for biological sample

Pore Sizes and Volumes. The filter size depends highly on the filtration volume. For small volumes (< 1 ml), syringe filters with a diameter of 3 mm are used for medium volumes (1-10 ml), 15 mm and for large volumes (> 10 ml) 25 mm. Common pore sizes for UHPLC and HPLC columns with small particle sizes (< 3 µm) are 0.2 and for columns with larger particle sizes (> 3.5 µm) 0.45 µm, respectively.
