BriScale™ VF Vacuum Filter / Storage Systems

Disposable Vacuum Filter 06-cbt.jpg

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 vacuum filtration product in China that supports integrity testing, which effectively guarantees the sterility of filtered samples.

Features and Advantages 

 ·  The scale line is clear and accurate;
 ·  The product is with light body, thick cup wall, low center of gravity, and wide bottleneck, which makes it easier to pour out the samples smoothly;
 ·  The connector is designed with threaded teeth shape to avoid side leakage risk;
 ·  The multi-stage design of the external vacuum interface is suitable for various specifications of hoses;
 ·  BriScale™ VF Single Use Bottle Top Filter and the receiver/storage bottle can be provided separately.
 ·  We deal the product with gamma irradiation sterilization, and sterile, dust proof double - layer packaging. So, it can be used directly.
 ·  All membrane types are tissue culture compatible, and heat-sealed to the support grid to maximize flow rate, and reduce foaming and protein denaturization


 ·  Used for the vacuum filtration of buffer, media and components, biological fluids, and other aqueous solutions. 
Used for filtration of tissue culture nutrient solution, biofluid and positioning buffer;
 ·  Used for filtering cell culture medium and other aqueous solution;
 ·  Used for filtering the solution that enable to be sterilized by autoclave.
