This basic economical water still is perfect for general laboratory and educational distillations. Borosilicate glass boiler and condenser provide the highest purity distillate. The unique condenser design ensures that the distilled water droplets remain in contact with the cooling coil for an extended period for maximum energy transfer and immediate cold distilled water.

Condenser with screw thread connections and plastic 3/8" ID hose barb fittings allow quick and safe tubing change without worrying about breaking the glassware. Easily descale without dismantling the glassware using the built-in acid addition funnel and wastewater drain. Long-life chromium-plated metal heater is protected by twin safety thermostats.

Please Note: Effective May 2022, the Stuart Water Still Model number W4000 has now been rebranded Cole-Parmer under Model number of WS-100-4. All the same great features and specifications, just with a new and improved look.
