A wide range and selection of top quality membranes are used for microfiltration and microbiological quality control in food, beverage, pharmaceutical, cosmetics and water testing industries. The GVS membrane filter range covers the main pore sizes, sterile and non sterile membranes and gridded types.


Membranas disponíveis:

GVS Maine Cellulose Acetate (CA) Filtration Membrane is a supported, hydrophilic membrane that is naturally low binding. It is ideal for use in filtration applications where maximal recovery of protein is critical. 

GVS Maine Nylon Filtration Membrane is a supported, naturally hydrophilic membrane designed to wet out evenly and retain its superior strength during use in general filtration or medical assays.

GVS Maine Polyethersulfone (PES) Filtration Membrane is hydrophilic and cast from pure polyethersulfone polymer. It is designed to remove particulates during general filtration, and its low protein and drug binding characteristics make it ideally suited for use in life science applications.

GVS Maine Nitrocellulose (NC) Filtration Membrane is an unsupported, hydrophilic membrane. It’s rapid flow rate and high throughput make it ideal for use in diagnostic kit manufacturing applications.

Regenerated Cellulose (RC) is a hydrophilic membrane. Resistant to a very wide range of solvents. Suitable for use with either aqueous solutions or organic solvents. Compatible with HPLC solvents. Very low protein binding capacity and hence excellent for protein recovery applications.

Polyvinylidene Difluoride (PVDF) is a hydrophilic membrane. Ideal for use in Sterilizing and Clarifying filtration of biological solutions. High Flow Rates. Low Extractables. Broad Chemical Compatibility.Very low protein binding.

PTFE (fine powder resin) is expanded into a 3-dimensional web-like structure called PTFE which creates billions of microscopic pores. This structure utilizes the inherent hydrophobic (water-resistant) and non-stick nature of PTFE to allow removal of particulate captured on the membrane surface. This allows air to pass easily through the membrane while collecting particulate as small as 0.1 micron on its surface. PTFE membranes and laminates provide device manufacturers with a consistent, temperature and chemical compatible barrier to microbes and particulate matter. The optimal combination of air flow and water entry pressure adds value to most device designs.
