The ELVAcard® high performance range of filter sheets is the result of continous research and development. These depth filters are produced of selected and pure raw materials. ELVAcard® is also a low-ion and low-pyrogen product with a high mecanical and chemical resistance.
The porosity of the sheets reaches 75 to 80 % to realize the retention of a high particle load and colloidal contamination. Addition of synthetic polymeres creates a positive electrokinetic potential (ZETA+) to assure the adsorption of
fine particles.
ELVAcard® high performance filter sheets resiste to nearly all waterous our organic liquids. They have been developed for the rougth, polishing and sterilizing filtration in various industries:

• food and beverages
• chemical
• cosmetic an pharmaceutical.

ELVAcard® high performance filter sheets are available in all common and in various special dimensions.
