 Description:

 Aquatron double water still

Produces 4 litres/hour double distilled water for higher purity levels. The first stage distillation is carried out in a

glassware set mounted at the front of the cabinet allowing easy access for descaling. The distilled water is fed to a

second set of glassware mounted at the rear and distilled a second time. The rear glassware is fitted with a level sensor

to ensure the heater is only activated when there is sufficient water in the boiler.

The pH of distilled water

Pure water, whether from a still, deioniser or reverse osmosis system, is an excellent solvent and will quickly dissolve

carbon dioxide from the air to form a very dilute solution of carbonic acid. In a water still this solution can form as

the steam liquefies in the condenser, resulting in a distillate output with a pH of 5 - 6.5. This is a normal level which

has little effect on most laboratory procedures. A slightly acidic pH value does not mean that the water is grossly

contaminated as a carbon dioxide level of less than one part per million will cause a pH of 5. If necessary the carbon

dioxide may be removed by boiling the water. It is then vital to protect the water from the air otherwise the carbon

dioxide will be re-absorbed quickly.
