Water Still (AutoStill)

The 4000X and 8000X are fully automatic, vertical boiler water stills, producing 4 and 8 litres / hr of ultra-pure pyrogen-free distillate, from any potable tap water supply. They are simple to operate and easy to clean.

  • Water flow rate automatically set and maintained
  • Automatic switch-off of water and heaters when distillate reservoir is full
  • Flowswitch automatically switches off heaters should water flow fall to an inadequate level
  • Borosilicate glassware and silica sheathed heaters
  • Fireproof toughened glass door
  • Boiler protected by external, independent thermal cut-out
  • Attractive zinc-plated steel casing has excellent corrosion resistance
  • Compact design, for bench or wall mounting

† Conductivity at 25¢XC 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.
