Barnstead™ MegaPure™ Deionizers

By Thermo
Barnstead™ MegaPure™ Deionizers

Barnstead™ MegaPure™ single or dual cartridge deionizers are useful for pretreating feedwater to most MegaPure™ stills. A deionizer connected to a MegaPure™ still allows for automatic control of feed water, reduces the scale build up and increases distillate purity. Temperature-compensated purity meter measures water quality and indicates when cartridges are exhausted. Two deionization models single (D1) or dual (D2) cartridge for greater flexibility in meeting varying feedwater qualities.

Built-in flow valve precisely controls flow to still, and drain valve allows no-spill cartridge changes. Large cartridge capacity for extended cartridge use. Unit can be wall or bench-mounted. 120V.
