Techne Sample Concentrator

E13-62 

   

This concentrator is designed for use in conjunction with a DB-3 series Techne Dri-Block® heater. It accelerates the concentration by solvent 
evaporation of large numbers of samples in a matter of minutes and it is a useful tool in the preparation of samples for analytical techniques 
including drug screening, hormone assay, chromatographic analysis and scintillation counting.
 
The Sample Concentrator consists of a fully adjustable gas reservoir which mounts over a DB-3 series Dri-Block®heater with a temperature 
range of 25°C to 200°C. When not being used for sample concentration the Dri-Block® may be used for routine incubation and temperature 
control of samples.

Application
As the samples are being heated, gas is passed via the gas chamber through hypodermic needles on to the surface of the test solution, 
providing for rapid evaporation and sample concentration.
 
The gas chamber is suitable for use with most inert gases and may be adjusted to suit the level of liquid in the sample tubes. Gas supply not 
to exceed 2psi. The 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 127mm are available for use in long tubes. Where 
corrosive solutions are being evaporated, PTFE coated needles are available. The compact nature of this unit enables it to be placed in a fume 
cupboard when toxic vapours are being evaporated

The Dri-Block® heater, insert blocks and needles must be ordered separately

 



Fast evaporation of solvents from any sample vessel

 



The unit is light and compact enough for convenient use in a fume cupboard when toxic solvents are being evaporated

 



The needles are made from high quality stainless steel and are specially designed for use with the Techne Sample Concentrator. When corrosive solutions are being used, PTFE coated 
needles are available

 



The Sample Concentrator's gas reservoir is mounted on a fully adjustable stand for accurate height control
