Sample Concentrator, 1 block, Individually Controlled Needles

Sample Concentrator, 1 block, Individually Controlled Needles

This sample concentrator has patented individually controlled gas needles for enhanced control.  Gas pressure is uniform from all needles. Simply close and open by moving needle up or down.

The nitrogen sample concentrator is used for concentrating or preparing samples in batches. It is used in processes such as drug screening, hormone analysis, liquid phase and mass spectrometry in the analysis of sample preparation. It works by blowing nitrogen in the surface of the sample which is being heated to accelerate evaporating and separating the solvent in the samples without oxygen. Instead of the rotary evaporation instrument, the nitrogen sample concentrator can efficiently concentrate dozens of samples simultaneously.

This is supplied with a BT1601-G 12 x 1.5ml Round Bottom Block.  See related products for a large selection of other sized blocks. Blocks with less than 12 holes need a different gas chamber to be compatible.

A gas flow control valve is also available for precise control of gas flow.


  • Patented individually controlled gas needles for enhanced control.  Gas pressure is uniform from all needles. Simply close and open by moving needle up or down.
  • Adjustable position of gas needle in air chamber plate for different types of tubes
  • Adjustable height of air chamber plate. The length of a standard gas needle is 150mm
  • The instrument can be put into a ventilation cabinet when the concentration sample is toxic solvents
  • Built-in overheating protection, automatic fault detection and fault alarm features
  • LED displays temperature and time. Operation is simple and convenient. Can be set for continuous operation.
  • Works by heating with dry bath in the bottom and nitrogen blowing on the surface which accelerates liquid evaporation and sample concentration
  • Standard configured air cavity and adjustable bracket.
