Tissue culture Media, Buffers, Protein Analysis/ Biological Samples |
CA, PVDF, PES |
|
High Particulate Loads |
With GF ｏｒ PP pre-filter |
|
Aggressive ｏｒ Pure Organic Solvents |
PTFE, PVDF |
Ø Step2: choose the suitable diameter

Ø Step 3: Choose the suitable pore size based on the nature of your sample
Removal of high particulate matter with a glass fber preflter is critical before any drug, tox, ｏｒ dirty environmental sample is fltered to ensure the highest syringe flter membrane performance.
Generally, 0.45 µm porosity flters are used to remove particulates from samples and mobile phase solutions. For sterile-fltration, a 0.20 µm porosity flter can be used.
