General Description
The Techne Sample Concentrator has been designed to provide a quick and convenient method of accelerating the
concentration by evaporation of solvents from samples prior to analysis. It is designed to work in conjunction with
Techne DB100/3, DB200/3, DB-3, and DB-3A Dri-Block
®
heaters
*
.
The Sample Concentrator consists of a gas chamber mounted above a Dri-Block
®
heater into which vessels
containing samples are placed. Hyperdermic needles carry the gas down from the chamber into the test tubes. The
samples are heated from below by the heater and the flow of gas directed over the surface of the samples displaces
the evaporated solvent from above the liquid’s surface. This significantly increases the rate of sample concentration.
The unit provides accurate and reproducible control over the positioning of the needles. The gas chamber can be
removed from its stand to provide easy access to the samples, and it can be replaced quickly. The whole unit is
compact enough for convenient use in a fume cupboard.
*
The Dri-Block
®
heater is not provided and must be purchased separately.
