The Merit® W4000 water still produces up to 4 Litres per hour of distilled water. It incorporates a glass boiler and high efficiency condenser which provides exceptionally high quality pyrogen-free distillate (although distillate should be tested). Screw threads are incorporated on all water connections so hoses can be fitted and removed easily and safely without risk of breakage. The metal heater is fitted with a thermal cut-out to protect the still in the event of water failure. A built-in funnel and stopcock allow the still to be cleaned easily without hazardous dismantling.
- Distillate cooled by high efficiency coil condenser
- Two independent safety thermostats
- Easy to clean without dismantling
- Can be wall or bench mounted
pH, conductivity and resistivity are affected by temperature and the presence of absorbed carbon dioxide. Specifications are based on tests conducted at 20 °C with CO₂-free water.
Care is needed to obtain pyrogen-free water and the distillate must be tested before use.
Water still heating elements are excluded from the 3 year warranty and are covered for 1000 hours use.
