Product Description:

Quickfit and Quartz launched their first ever Water Stills more than 60 years ago. Now SciLabware is proud to re-introduce the Quickfit® name into the water distillation market with the new Quickfit® QWS4 Water Still.

Manufactured in the UK, the QWS4 combines high performance with value for money. Other Water Stills may look similar, but only the QWS4 features a high-quality Pyrex® glass boiler and condenser.

Key Features

• Easy to install and easy to use
• Reliable operation – proven quality components
• High-quality distillate complies to ASTM
• and ISO standards
• Safe operation – heating element has two built-in
• safety thermostats
• Easy to clean – no glass dismantling required
• CE marked

Safety First

The chromium plated heating element is fitted with two thermostats to protect the still from overheating in the event of water supply failure.

The thermostats can be reset to resume Water Still operation when the water supply has been restored.

Efficient Cooling

The highly efficient Pyrex® glass coil condenser, fitted with detachable plastic screw thread connectors, ensures that the distillate is cooled ready for use.

Easy Cleaning

No dismantling required. The Pyrex® glass boiler is fitted with a built-in funnel to allow the quick and easy addition of cleaning solutions.

Once the cleaning solution has done its job, simply open the GP Rotaflo® PTFE stopcock to drain the solution out of the boiler.

Quality Distillate

The QWS4 will produce 4litres/hour of pyrogenfree* distilled water from its reliable 3kW UK manufactured, chromium plated heating element.
