BriScale? VF disposable vacuum filter / storage systems, provides a complete solution for your filtering needs. The vacuum filtration system consists of a polystyrene filter funnel joined by an adapter to a removable receiver / storage bottle, which can be easily unscrewed from unit and can be sealed with a plug cap for filtrate storage.  

BriScale? VF for Filtration of High Viscosity Fluids Media 
In R&D process of biological laboratories, many samples are filtered, separated and purified everyday. The chemical properties, particle size, water solubility, viscosity, and protein characteristics of the filter medium will affect the difficulty of separation and purification. Vacuum Filter Unit, a frequently used lab filtration device, can provide the best filtering solution accordingly.

BriScale? VF Bottle Tops and Filter Units uses vacuum filtration to provide power, which can not only increase the flow rate and flux, but also reduces the retention volume of the medium to be filtered. It can be used for filtration of high viscosity fluids media. 

In terms of sterilization and filtration of cell culture media, buffers, etc., BriScale? VF can be equipped with different material membranes such as PES, PVDF, PTFE, etc.

In addition, BriScale? VF can use a special test kit to achieve integrity testing. The only vacuum filtration product in China that supports integrity testing, which effectively guarantees the sterility of filtered samples.
