Water Stills, Distinction
D4000
• All glass construction
• Two independent safety thermostats
• Safety reservoir full shut off
• Wall mountable
• Silica sheathed heaters
Key Features
All glass construction with silica sheathed heaters ensures top
purity distillate at an economical price. Fitted with a control
device to turn off the heater when the collecting reservoir is
full. Prevents overflow if the still is inadvertently left switched
on when unattended. With two independent safety thermostats
to prevent over heating in the event of an interruption to the
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 producing cold distilled water and pre-
heating the boiler feed to increase efficiency. Screwthreads
are incorporated on all water connections so hoses can be
fitted and removed easily and safely without risk of breakage.
Built in acid addition funnel and drain stopcock allow easy
descaling without dismantling the glassware. The stand is pre-
drilled to facilitate wall mounting.

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.
