qpore® - Finest Filtration

The qpore® laboratory filter portfolio offers a wide range of blotting membranes, bottletop, liquistop, membrane and syringe attachment filters always to suit your needs. Particularly chemical-resistant, durable, blotting membranes made of hydrophobic PVDF (polyvinylidene fluoride) and sensitive CN (cellulose nitrate) ensure background-free blots and optimal bands, due to a high protein binding capacity - without prior soak in organic solvents (PVDF). bottle-top filters, which are particularly suitable for filtration of larger sample quantities. Filters from CA (cellulose acetate), PES (Polyethersulfon) or PVDF show high flow rates, with very low protein binding. They are free of detergents, sterile, pyrogen-free and are therefore ideally suited for filtration of cell culture media.

Sterile qpore® syringe filters have a hydrophilic membrane made of PES or CA - with a high mechanical and chemical resistance with minimal protein absorption. Due to an excellent flow rate, they are optimally suited for sterile filtration, clear filtration and cell removal under sterile conditions

The hydrophilic, non-sterile qpore® membrane filters made of (CME) are made up of CA and CN and are characteristic of a soft, homogeneous surface structure. Thanks to effective retention properties, high flow rates, and excellent thermal resistance, these membrane filters are suitable for a wide range of applications from clear and sterile filtration to air particle analysis.
