The Techne FSC400D Sample Concentrator is a fully adjustable gas reservoir and stand for tubes that is mounted on the Dri-Block DB3 series heater unit.
It can be used to concentrate samples which are corrosive, by just a change of needles. These needles are fixed on a matrix of silicone rubber which enables their positions to be changed to suit different tube configurations.
Standard 76mm needles are the norm, while longer 127mm needles are used for larger samples. The needles are either stainless steel (for general purpose) or PTFE needles for corrosive substances.
The gas chamber is adjustable to suit the level of the liquid in the sample tubes. Also, the units can be used within a fume cupboard.
The Techne Sample Concentrator accelerates the concentration of large numbers of samples in a matter of minutes, where traditional methods can take hours. It is ideal for the life science researcher and chemist alike designed for applications such as sample preparation, drug screening, hormone assays, chromatographic analysis and scintillation counting.
Unique Gas Chamber
Evaporation is increased by passing an inert gas over the surface of the sample to remove any evaporated solvent molecules, maintaining the concentration gradient. The gas travels through the unique patented gas chamber to the samples via the needles. The needles are inserted into a silicone matrix and can be spaced to fit varying combinations of tubes from 26mm tubes to 0.2ml
