Autostill™,
AutoFour Range of Water Stills
A range of fully automatic horizontal boiler water
stills, producing ultra-pure, pyrogen-free distillates.
- Flow regulator automatically sets and maintains
correct water flow rate
- Fully automatic operation with ‘switch-off’ of
water and heaters when distillate reservoir is full
- Borosilicate glassware and silica sheathed heaters
- Boilers protected by two independent thermal
cut-outs
- Efficient condenser design gives cool distillates
- Zinc-plated steel casing has excellent corrosion
resistance
- For bench or wall mounting
Autostill™,
AutoFour
A competitive distillation unit producing 4 litres/hr of ultra-pure, pyrogen-free
distillate from any potable water supply. The boiler is designed to minimise
cleaning requirements and features a by-pass flushing arrangement to simplify
acid cleaning.
Autostill™,
AutoFour WS
The AutoFour WS is similar to the AutoFour, but has its own water-softener
to prevent the formation of scale in the boiler, eliminating the need for periodic
boiler cleaning. Regeneration of the softener is easy and inexpensive, merely
requiring flushing through with sodium chloride solution
Autostill™,
AutoFour D-Ionstill 4 Litre
The D-Ionstill is designed for connection to any standard laboratory deioniser,
to produce an exceptionally high-purity distillate. The Autostill™ controls
the flow of water from the deioniser, conserving deionised water – tap water
is used to cool the condenser. Since deionised water is used the boiler should
never require cleaning.
Autostill™,
AutoFour D-Ionstill 8 Litre
A larger, twin boiler version
of the D-Ionstill, producing 8 litres/hr of ultra pure, pyrogen-free distillate.

† Conductivity at 25°C
with dissolved CO2 removed from distillate. Any
ultra pure water in contact with the atmosphere has a conductivity
of 1-2 µs/cm and pH 5, due to a small amount of CO2 (0.5ppm)
absorbed from the atmosphere. Deionisers and similar systems
measure conductivity before the water contacts the atmosphere
and absorbs CO2 (during collection and use). As distillates
are already open to the atmosphere before measurements can be
made, it is necessary to remove this CO2 to provide
a comparable conductivity value.
