12A Water Still 2-1
Thermo Scientific
Section 2
Introduction
The Thermo Scientific MEGA-PURE 12A Water Still is a compact, all
glass and Teflon® unit designed to provide 12 liters per hour of high purity
distilled water. The product water, as produced, is non-pyrogenic per
U.S.P. XIX and will have a resistivity up to 10M ohm-cm or higher at the
product outlet using most tap water as feed. The MEGA-PURE 12A
Water Still has a built-in deionization system designed to pretreat the
boiler feed water. Each unit also has a product cooler to reduce the
temperature of the distilled water from 85°C to about 55°C for ease of
handling. Pretreatment may be required to achieve >1.0M ohm/cm water.
This Water Still can be used as a discrete unit, or it can also be connected
to the Thermo Scientific Automatic Collection System for complete
automatic operation.
The MEGA-PURE 12A is rated at 240V, 50/60 Hz, 10,000 watts, single
phase. It is also available in 208V. Changing the unit for use on either
240V or 208V operation requires only replacing the four Vycor®
immersion heaters with heaters having the required voltage rating. The
electrical controls have been designed to operate on voltages between 208
and 240 volts A.C.
The cabinet and glassware are protected against damage from overheating
by two thermal switches. Restoration of operation requires allowing the
unit to cool down for 5 - 15 minutes and restarting.
Choice of a location for your MEGA-PURE 12A Water Still is primarily a
matter of convenience. This unit may be located on a bench or wall
mounted. This water still may be connected to the Automatic Collection
System for complete automatic operation.
