High-Quality Pyrex Glass Components in a Water Still

SciLabware's Quickfit range has introduced a new QWS4 Water Still. Manufactured in the UK, the QWS4 is the only water still on the market made with high-quality Pyrex glass components - for its boiler and condenser. The QWS4 produces around 4 litres/hour of pyrogen-free* distilled water. Its chromium plated 3kW heating element is fitted with two thermostats to protect from overheating in the e...

What is the pH of distilled water?

Purified water from distillation, deionisation or reverse osmomsis purification systems will usually have an acidic pH. But why is the pH of distilled water not neutral pH 7? This does not mean the water is contaminated - we've taken a look at the chemistry that explains the acidity.

To obtain optimum performance from the still the scale should be removed on a regular basis. The time span between cleaning depends entirely upon the hardness of the water supply. In very hard wate...
