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
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.

Installation
For packing purposes the Sample Concentrator is supplied unassembled in three parts; the base board, the column
and carriage, and the gas chamber. The unit is re-assembled as follows:
1. Unscrew the column fastening knob from the column support bracket already fixed to the base board.
Locate the column on the two pins in the support bracket. Screw the fastening knob through the rear of the
column and tighten firmly.
2. Align the threaded hole on the back of the gas chamber with the mounting on the carriage. Tighten the
locking knob to secure the gas chamber in position.
3. Connect the intake nozzle at the rear of the gas chamber to a suitable supply of gas via a pressure reducing
valve. The gas pressure should be adjusted as required at the reducing valve but should not exceed 2 psi.
Pressure in excess of 2 psi will cause gas to be vented and wasted.

4. Place the Techne Dri-Block
two spigots on the base board which align with two centrally located screw heads on the underside of the
Dri-Block® unit.
