With the launch of the Vacuum Controller V-855 we also introduced a new function which automatically determines the start-point of a distillation process. This so-called EasyVac algorithm is essentially based on pressure changes over time.
Whilst the first EasyVac version has proven to be a reliable tool for the routine evaporation of solutions with one organic solvent, it was rather limited for solvent mixtures. This, and the demand for a suitable tool for automatic parallel evaporation with the Multivapor, triggered the development of a new EasyVac function applicable to all kinds of solvent mixtures, glass assemblies and even the Multivapor.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.CentrifugesCentrifuges are used to separate particulates suspended in a liquid via the application of a centrifugal force including cells, macromolecules, nanoparticles and precipitates. Centrifuges come in three sizes: microcentrifuges, benchtop and floor-standing centrifuges, depending on the volume and number of samples that require separation. When choosing a centrifuge, consider its maximum separation power indicated by its relative centrifugal force (RCF) value. Low force centrifuges reach a maximum RCF of 8,000 g, high-force centrifuges can reach maximum RCF values of 80,000 g. For extremely high forces, consider ultracentrifuges (up to 800,000 g). Refrigerated and vacuum centrifuges also known as concentrators are available for more specialized applications. A range of volumes are available for centrifuge tubes and microfuge tubes, depending on sample sizes.
