Techne accelerates sample concentration

The height-adjustable head of the concentrator delivers a flow of inert gas that removes evaporated solvent from the surface of solutions in tubes or 96-well plates.

Traditional methods of reducing the volume of solvent or diluent can take many hours, requiring the use of centrifugation, vacuum, heat and expensive cold traps, while also causing sample loss.

By combining heat from below with a flow of inert gas to the liquid surface, the Techne Sample Concentrator and Dri-Block heater have been shown to provide fast and easy solvent evaporation without loss of sample quality or quantity.

The concentrator features a gas chamber mounted on a fully adjustable stand for accurate height control.

Inert gas, usually nitrogen, is directed onto the sample surface via a set of high-quality stainless-steel needles positioned in a silicon matrix according to the required spacing.

Any sample format can be accommodated, as the concentrator is available in two models: one for 0.2ml micro centrifuge tubes, test tubes, boiling tubes, cuvettes and other small containers; and one for 96-well plates and deep-well storage plates.

The Techne Sample Concentrator is suitable for use in drug screening, hormone assays and chromatographic analysis - as well as in industrial settings where it is important to remove solvents or increase the concentration of samples.

It will be especially useful for both combinatorial chemistry, for which users can concentrate compounds directly in standard 96-well storage plates; and microarrays, which require a high sample concentration of RNA, DNA or protein.

The Techne Sample Concentrator is supplied with a three-year warranty and can be used with either a nitrogen generator or gas cylinder.

The lightweight and compact unit can easily be placed in a fume cupboard when toxic solvents are being evaporated.

PTFE-coated needles are available for use with corrosive chemicals.
