GH Polypro filters are all-purpose disk filters, ideal for filtering samples and HPLC mobile phases. Composed of hydrophilic polypropylene for maximum chemical compatibility with aqueous solutions or aggressive chemicals. Resistant to such harsh solvents as DMSO. High recoveries of critical, proteinaceous samples due to low protein-binding nature. Available in 0.2 and 0.45µm pore sizes. Typical filters thicknesses are 0.2 µm: 101 µm (4.0 mils) and 0.45 µm: 114 µm (4.5 mils).
Minimum bubble points — water are, for 0.2 µm: 2.9 bar (290 kPa, 42 psi); for 0.45 µm: 1.38 bar (138 kPa, 20 psi). Typical water flow rates are given for 0.7 bar (70 kPa, 10 psi) pressure.
