Vacuum Filters

Cobetter bottle-top vacuum filters features high flow rate and super low protein binding, providing reliable sterile filtration of cell culture media and buffer. Cobetter PES membrane vacuum filters offer fast flow rate and low protein-binding of aqueous solutions. Hydrophilic PVDF membrane vacuum filters offer broad chemical compatibility and very low protein binding.

Overview

Cobetter Briscale disposable vacuum filter units are used for filtration of biological samples, cell culture, tissue culture media, buffer and other aqueous solutions. They are vacuum-driven pressure filters and are designed for large volume sample filtration with different sizes including 150mL, 250mL, 500mL and 1000mL. The filter unit consists of a polystyrene bottle-top filter funnel joined by a HDPE adapter, a polystyrene lid, a polystyrene receiver bottle and a separate HDPE cap.

Membranes

Asymmetric PES (Polyethersulfone) membranes provides high flow rates and low protein binding, which are recommended for filtering culture media
Hydrophilic PVDF (Polyvinylidene Fluoride) membranes features very low protein binding and low extractable, which are ideal for filtration of protein-rich solutions

Applications by Pore Size

0.1 µm for mycoplasma removal.
0.2 µm for the sterile filtration of cell culture, media, buffers, and reagents.
0.45 µm for the clarification of aqueous and viscous solutions.
