Traditional methods of biological sample concentration can take hours and require the use of centrifugation, vacuum, heat and expensive cold traps. Techne, the life science equipment brand from Barloworld Scientific, has developed a Sample Concentrator that will provide a fast and convenient alternative method of simultaneously concentrating multiple biological samples. Ideal for researchers and scientists preparing samples for analytical techniques including drug screening, hormone assays and chromatographic analysis, the Techne sample concentrator will concentrate up to 90 samples in minutes. High quality stainless steel hypodermic needles are set in a silicon rubber matrix of a unique patented gas chamber enabling their positions to be change to accommodate different tube configurations. The whole unit is light and compact enough for convenient use in a fume cupboard when toxic vapours are being evaporated. Every unit is supplied with a 3-year warranty.
