The VP 220 is ideal for rotary evaporators providing the powerful vacuum needed for demanding evaporations without the use of oil pumps. VP 220 has built-in Advanced Vapour Management (AVM) which means precise control capability for the distillation of organic solvents and applications handling aggressive vapours and gases. The VP 220 is especially effective for rotary evaporation of low boiling point solvents such as acetone and ethanol and is able to rapidly strip DMF at 35 °C. The pump parts are all made of corrosion resistant materials such as PTFE and Kalrez to handle aggressive vapours, and together with vacuum adjustment, the evaporation process will be optimised. Use the vacuum adjustment to increase the vacuum until bubbles form in the evaporation flask - then lower it slightly. Reduce the vacuum for fast reaction to bumping or foaming.

PolarSafe Dots are made from chemically inert polyester with a unique adhesive formulated to adhere to laboratory glass and plastic ware. These dots will not only withstand conventional freezing (−80 °C) but can also be used for most cryogenic storage applications (vapour phase nitrogen storage at −196 °C). No need for separate labelling solutions for your cryo-preservation units and your ultra low freezers. The labels can even be used in incubators. PolarSafe Dots do not require self lamination to be effective. The sleeker labels mean your tubes will still fit most storage systems without the label sticking or being torn off. The wide range of sizes allow you to label your whole experiment permanently, from micro-centrifuge tube to cryovial, microtiter plate to storage boxes.
