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

The Neon® Transfection System enables fast and efficient delivery of nucleic acids into all mammalian cell types, including primary, stem, and difficult-to-transfect cells. The flexible and open system allows the user to perform high-quality transfections using optimized or user-defined protocols in three simple steps with as few as 2 × 104 cells per reaction. A novel reaction chamber provides a dramatic increase in transfection efficiency and cell viability. The Neon® Transfection System is:

• Efficient—up to 90% in many cell types, including difficult-to-transfect cells, primary, and stem cells
• Flexible—easily transfect from 2 × 104 cells to 6 × 106 cells per reaction
• Simple—easy to use, with a single reagent kit for all cell types
• Versatile—open system allows electroporation parameters to be optimized freely

Polarimeters are ideal for analysing optically active substances by determining their angle of rotation. They support all applications in industry, research, development and education.
