Specifications and features *Water Still (fully automatic) for double distillation, suitable for both bench and wall mounting. *Very good distillate quality; conductivity: single distillate: approx. 2.2 µs/cm at 25 °C double distillate: approx. 1.6 µs/cm at 25 °C (see "Technical Details"). *Electronic level control during the whole distilling process. *Electronic impurity detector switches the unit off in case of high degree impurities of the water in the evaporator 1st stage, the red pilot lamp "Clean" will glow. *Double-action low water cut-off through float switch and thermostatic safety switch. *Economical energy consumption by distillation of the heated cooling water. *Water saving through automatic water cut-off. Unnecessary water consumption will be avoided. *Condenser (cooler): 1st stage made of stainless steel; 2nd stage including the baffle made of DURAN® Borosilicate 3.3 glass. *Evaporator easily accessible for cleaning purposes . *Distillate withdrawal: valve made of Borosilicate glass 3.3 with PTFE plunger for single distillate, outlet with dust guard shield made of Borosilicate glass 3.3 for double distillate. *CO2 degassing through outlet in the condenser. *Heating element and evaporator made of stainless steel. *Double-walled housing. Outer housing made of electrolytically galvanised sheet steel, electrostatically powder-coated with epoxy resin. *Water supply through a built-in solenoid valve with connection for pressure hose 1/2" (inner ø approx. 12.7 mm). *Main switch with pilot lamp for the monitoring of both distillation stages at the front of the unit.
