Manufactured in the U.K., the QWS4 combines performance and reliability with exceptional value for money. This new water still incorporates a number of operational and safety features that make this still the ideal choice for your laboratory. • Output capacity 4Litres/Hour pyrogen free* single distilled water • Distillate quality complies with European Pharmacopoeia for Purified Water & A.S.T.M. Type 4. • Pyrex® glass boiler and condenser minimise potential contamination of distillate from the leaching effect of distilled water on metal components • Distillate pH5.0-6.5 • Distillate conductivity 3.0-5.0uS/cm • 3kW chromium plated heating element with 2 independent re-settable thermostats protect the still in the event of water supply failure • Easy to clean. No glassware dismantling is required • Available in 230V, 220V and 120V versions. Output capacity of 120V model is around 2.4Litres/Hour • Can wall or bench mounted • CE marked by independent testing agency • Supplied with an instruction/operating manual • All of the major components are available as spare parts *We recommend that the distillate is tested before use

• Shore A, 0 and D to measure the hardness of plastics through penetration measurement
• Shore A rubber, elastomers, neoprene, silicone, vinyl, soft plastics, felt, leather and similar material
• Shore 0 foam, sponge
• Shore D plastics, formica, epoxides, plexiglass etc.
• Material thickness of the sample: min. 4 mmDelivered in a hard carrying case
• Particularly recommended for internal comparison measurement. Standard calibrations e. g. to DIN 7619-1 are often not possible because of very narrow standard tolerances
• Can be attached to the test stands TI-ACL (for Shore A and A0), TI-DL (for Shore D) to improve measuring uncertainty
• Large display with backlight
• Selectable: AUTO-OFF function or permanent operation, battery level indicator
