What is Vacuum Filtration
GVS Disposable Vacuum Filtration Systems is specifically designed for the filtration of culture media and organic solvents in research and industrial laboratories.
They are purpose-built with features designed to bring the highest levels of performance and purity to your research. It is possible to choose from a variety of membrane types and membrane areas that offer a wide applicability range for separation and purification of most liquid samples to meet different laboratory needs. It should be driven by vacuum pumps.
The filter system is manufactured with high quality material (ABS, PP or GPPS) which assure it works under pressure and still hold integrity.
How to choose the filter media?
Follow the below guides to choose the right filter media for your application.
Nylon: providing a broad range of chemical compatibility of the filtration of either aqueous or organic solvents, hydrophilic. Can be used in a broad pH range.
PVDF (Polyvinylidene fluoride): extremely low protein-binding, for filtration of non-aggressive aqueous and mild organic solutions, or where maximizing protein recovery is important.
PES (Polyethersulfone): low-affinity for proteins and extractable with substantially faster flow rates
Suitable for pre-filtration and filtration of buffers and culture media.
MCE (Mixed cellulose esters): high protein binding and resistant to mild acids, hydrocarbons, formaldehyde and petroleum ethers. Ideal for clarifications of aqueous and chemical solutions.
CA (Cellulose Acetate): lowest binding material available, hydrophilic and high throughput, strength and dimension stability, uniform pore structure.
Can I buy the units separately?
Yes, customers can buy only the bottle-top filter or the receiving bottle separately based on different needs.
Is the product sterile?
Yes, each product is individually packed in a plastic bag and sterilized with Gamma Ray Irradiation.
