E-Cell* MK-3Pharm Stack
Electrodeionization (EDI) Stacks for Pharmaceutical Applications
E-Cell *MK-3Pharm is designed to:
 Provide Ultrapure Water for Pharmaceutical
applications.
 Produce Mixed Bed quality water on a
continuous basis.
 Require no caustic or acid for regeneration of
mixed bed resin within the stack.
 Be leak free, guaranteed
 Eliminate brine injection and concentrate
recirculation, simplifying system design.
Description and Use
MK-3Pharm E-Cell stacks are electrodeionization
(EDI) stacks which use electrical current to deion-
ize and polish reverse osmosis (RO) permeate wa-
ter. The product water for the MK-3Pharm is at
greater than USP quality levels required in today’s
Pharmaceutical applications.
Typical Application
 Pharmaceutical
 Laboratory
Quality Assurance
 CE, UL & CSA marked
 Manufactured in a ISO 9001:2000 facility
