The Merit W4000 is the ideal choice for budget conscious laboratories that can't afford to compromise on quality. It combines economy and high performance with a host of other features which comparable stills cannot match. Built in acid addition funnel and drain stopcock allow easy descaling without dismantling the glassware. 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. Screw threads are incorporated on all water connections so hoses can be fitted and removed easily and safely without risk of breakage. Safety features include two independent safety thermostats to prevent over heating in the event of failure of the water supply. The stand is pre-drilled to facilitate wall mounting.The borosilicate glass boiler is fitted with a 3kW chromium plated heater producing distillate flow rates of up to 4 litres per hour which is ideal for the busy laboratory. Its robust metal stand allows A thermostatic cut-out has been incorporated in its design.Non-Automated System - Does not have an auto cut off functionOutput: 4 litres per hourWater consumption: 1 litre per minuteDistillate: Pyrogen-freeConductivity: 2.0 - 3.0 µScm-1Temperature: 25-35°CElectrical supply: 220-240V 50-60HzDimensions: 470 x 150 x 450mm width x depth x heightMass: 6kg
