Key Features
Three models are available giving outputs of 4 or 8 litres/hour
single or 4 litres/hour double distilled water.
The high quality borosilicate glassware coupled with silica sheathed
heaters gives pyrogen free distillate of the highest purity from
virtually any raw water supply.
The unique condenser design ensures that the droplets of distilled
water remain in contact with the cooling coil for the longest
possible time ensuring maximum energy transfer. This produces
cold distilled water ready for immediate use and pre-heats the
boiler feed to increase efficiency.
All glass construction allows rapid descaling using strong mineral
acids. A built in “clean” function and integral acid addition
funnel make the cleaning operation simple and safe with no need
to dismantle any of the glassware. A large bore stopcock with
PTFE key is fitted for easy draining of chemicals after cleaning.
A flow sensing device will detect any reduction in the flow of
cooling water to below the required level and will turn off the
still before it can overheat. Sensing the flow of cooling water
rather than its pressure is safer and allows the still to run normally
on low pressure supplies down to 3psi (20kPa). As a fail-safe device
there is an over-temperature thermostat mounted in the boiling
chamber.
The Aquatron® is very easy and safe to assemble and maintain. Both
the acrylic safety screen and the cabinet lid are removable giving
unrivalled access to the glassware components. Screwthreads are
incorporated on all water connections so hoses can be fitted and
removed easily and safely without risk of breakage.
Every Aquatron® water still is supplied with a reservoir level control.
The control is a simple and effective system which can be fitted to
virtually any type of reservoir vessel. It will turn the still off when
the reservoir is full and restart it when the level in the reservoir
drops as distilled water is removed for use making it fully automatic.

Conductivity and resistivity are affected by the presence of
dissolved carbon dioxide. All figures given in this catalogue are
based on tests carried out on the still output at 20°C and free
from carbon dioxide.
