The Stuart W4000 Merit Water Still by Cole Parmer produces four litres of single distilled water in one hour. A basic model ideal for educational or laboratory applications. Both the condenser and boiler are made from borosilicate glass. Designed to last, the metal heater is chromium-plated. Two safety thermostats prevent overheating should the water supply be interrupted. The condenser ensures distilled droplets have extended contact with the cooling coil, giving cold distilled water and pre-heating the boiler feed providing energy-saving.
Included is an acid addition funnel and stopcock for draining descaling chemicals, both remove the need for dismantling glassware during cleaning.
Water connections are screw thread and plastic 3/8″ ID hose barb fittings to make hoses changes easy and avoid glassware breakage.
