DESCRIPTION
Dorsan® PVDF filter cartridges are manufactured with two layers of high-performance filter membranes. This design — which incorporates a pre-filter layer — efficiently reduces the clogging rate of the final filter membrane. Our filters have a longer useful life and better performance than the products of our competitors. The end result maximizes flow rates and performance.
Dorsan® PVDF filters offer wide chemical compatibility with the standard cleaning products available on the market.
FEATURES

High performance.
Lower clogging rate.
Longer useful life and better performance.
APPLICATIONS
Filtration in the food and beverage industry
Retention of particles and micro-organisms
Protein purification
Cell culture clarification
Blood filtration
Cell cultures
Pharmaceutics
