The Techne Sample Concentrator accelerates the concentration of a large number of samples in a matter of minutes, where traditional methods can take hours. It is ideal for researchers in the life sciences and chemistry well designed for applications such as sample preparation, drug screening, hormone assays, chromatographic analysis and scintillation counting. The evaporation is enhanced by passing an inert gas over the surface of the sample to remove any solvent molecules evaporated, maintaining the concentration gradient. The gas moves through the gas chamber and patented single sample through the needle. The needles are inserted into a matrix of silicone and can be spaced to accommodate various combinations of tubes of 26 mm to 0.2 ml tubes microtubes. It comes with the following key benefits: 1) Fast evaporation of solvents from any sample vessel, 2) The unit is light and compact enough for convenient use in a fume cupboard when toxic solvents are being evaporated, and 3) The Sample Concentrator's gas reservoir is mounted on a fully adjustable stand for accurate height control.
