High Quality Stainless Steel Filters Fitted With Genuine Doulton® Cleanable Ceramic Cartridges For Economical Absolute Micro-filtration - A Practical Alternative to Costly Throw-Away membranes!

Ceramic cartridges for critical micro-filtrationThe ceramic cartridge membrane offers both; absolute dead-end filtration and depth filtration. Far more economical absolute micro-filtration than any thin film poly-carbonate, polyester or teflon® dead-end membrane or throw-away depth filtration membrane made of PVC, PVDF, PTFE, cellulose, nylon, polyethersulfone, polypropylene.

Unlike the man-made materials used in dead-end and depth filter membranes, Sterasyl® have pure silver through-out the ceramic shell preventing bacterial growth for safe handling and cleaning. Cartridge efficiency is >99.99% at 0.9 µm absolute (0.5 µm absolute ANSI standard), >99.9% at 0.5 - 0.8 µm and >98% at 0.2 - 0.5 µm.
