The QWS4 Water Still is a compact, easy-to-use laboratory distiller that produces high-quality single-distilled water at up to 4 liters per hour for school laboratory applications.
The QWS4 Water Still is designed for educational laboratories that require a reliable and affordable source of distilled water. Constructed from sturdy borosilicate glass, the still allows clear visibility of the entire distillation process while maintaining durability for routine lab use. The unit features a built-in thermostat and dual safety thermostats on the heating element to protect against overheating if the water supply fails. Mounted on a metal stand for benchtop or wall placement, the still is simple to install and operate. Cleaning is streamlined through an integrated funnel and drain system, eliminating the need to dismantle glass components. The QWS4 produces single-distilled, pyrogen-free water that complies with ASTM and ISO standards when properly operated and tested, making it suitable for chemistry labs, glassware rinsing, and general laboratory use.
