The Techne sample concentrator accelerates the concentration of large numbers of samples in a matter of minutes compared with traditional techniques which may take several hours. This makes the unit a particularly useful tool in the preparation of samples for analytical techniques including drug screening, hormone assays, chromatographic analysis and scintillation counting.
The sample concentrator consists of a fully adjustable gas reservoir which mounts over a precision controlled DB-3 series Dri-Block heater with a temperature range of 25°C to 200°C. This enables samples to be heated quickly and efficiently to the required temperature to assist evaporation.
When not being used for sample concentration the gas chamber can be removed and the Dri-Block used for routine incubation and temperature control of samples for a wide range of laboratory applications.
As the samples are being heated gas is passed via the unique gas chamber through hypodermic needles on to the surface of the test solution, so providing the environment for rapid evaporation and sample concentration. The hypodermic needles are set in a silicone rubber matrix assembly enabling their positions to be changed to accommodate different tube configurations.
The standard 76mm long needles are suitable for most applications but where large samples require evaporation in long tubes packs of 127mm long needles are available.
The gas chamber is suitable for use with most gases and may be adjusted to suit the level of liquid in the sample tubes to give even faster evaporation times.
The unit can be placed in a fume cupboard when toxic vapours are being evaporated.
The Sample Concentrator comes complete with gas chamber and stand.
A DB-3 series Dri-Block Heater and insert blocks are also required and must be ordered separately.
Overall dimensions (LxWxH) are 295x240x530mm.
Gas supply should not exceed 2 psi.
