The Distinction Water Still lives up to its name - rapid, reliable, convenient and economical. The distinctive features of the Distinction show a care in design that puts it apart from other budget water stills, providing safety and quality at a competitive price. With a range of benefits usually associated with more expensive models, the Distinction represents unbeatable value for money.
To prevent the still from overheating in the event of cooling water supply failure, the Distinction is fitted with two independent thermostats. One is mounted in the condenser vent tube and will quickly detect coolant supply failure and turn off the heater. The second is mounted inside the boiler and will turn off the heater if the water level becomes too low - e.g. caused by glassware breakage or if the drain is accidentally justify open. The second thermostat also acts as a back-up to the first for extra security.
The all-glass construction including silica sheathed heating element ensures high quality distillate, complying with the European Pharmacopoeia for purified water and ASTM type 4. As there is no metal in contact with the water the Distinction eliminates the risk of metal ions leeching out into water causing contamination. The metal support stand allows the still to be either bench or wall mounted.
The Distinction Still is supplied complete with a level control device which clips into the collecting reservoir and will automatically turn off the heater when the reservoir is full. This allows the still to be justify running unattended without risk of the reservoir overflowing. The Built in PTFE drain stopcock and acid funnel allow easy cleaning without dismantling the glassware.
* pH, conductivity and resistivity are affected by temperature and the presence of absorbed carbon dioxide. The basis of the tests is 20°C on distilled water free of carbon dioxide.
** Care is needed to obtain Pyrogen-free water and the distillate must be tested before use.
