General Description
The Cole-Parmer 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 Cole-Parmer DB100/3, DB200/3, DB-3, and DB-3A Block Heaters
* .
The Sample Concentrator consists of a gas chamber mounted above a 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 Block Heater is not provided and must be purchased separately.
