TT-200N-VSC Visible Sample Concentrator

Product Description

TT-200N-VSC Visible Sample Concentrator is intended to provide rapid evaporation of solvents
from samples in test tubes or containers. It works under the principle of solvent evaporation to
concentrate samples. By heating the samples/ solution in a dry block heater coupled with a stream
of inert gas (nitrogen) direct to the surface of the sample, vapour is rapidly driven off and the sample is
quickly concentrated. The unique design of the block enables sample level to be observed during

The sample concentrator is built with gas manifold plate mounted onto a height adjustable stand which
allows flexible positioning above the samples. There are 12 independent gas control valves that
are used to control the gas flow towards the surface of each sample via gas needles. Furthermore, any
unused needle can be lifted conveniently to avoid gas wastage. It is a compact device commonly used
to replace high cost rotary evaporators and safe to be used in fume hood.


  • Concentrate dozens of samples simultaneously
  • Sample level of the concentrate can be observed during operation
  • 12 independent gas control valves and optional flow regulating valve minimize wastage of nitrogen gas
  • Can be used in fume hood when concentrating toxic solvents
  • Adjustable gas needle position to suit different types of sample tubes
  • Simple installation, operation and maintenance
  • Built-in over temperature protection device, automatic fault detection system and alarm function
  • Digital display of temperature and time
  • Compact foot print, fits all standard fume hood


  • Molecular biology, drug screening and analytical procedures (HPLC, GCMS), hormone assays
  • Remove solvent from DNA samples
  • Chromatographic analysis
