The instrument must be placed near a water tap (necessary for cooling the distillate)
with a maximum pressure of 5 bar, and sink in order to discharge the waste water.
The instrument requires a tap water flow rate (depending on the temperature of the
tap water) of approximately:
- 0.5 l/minute at a temperature of 15°C
- 1 l/minute at a temperature of 30°C
Water is required during the distilling phase only and is interrupted automatically
during the other phases.
Position the
tanks for NaOH and H

The hydraulic tubes are supplied with the
instrument and the hydraulic connections
are clearing identified on the rear of the
instrument.
