Water Bath Sample Concentrator SMI-WT-12



JINDAL water bath concentration is mainly used for concentrating or preparing samples in batches. Such as drug screening, hormone analysis, liquid phase analysis, and mass spectrometry in the analysis of sample preparation. It works by blowing nitrogen onto the surface of the sample, which is being heated, to accelerate evaporation and separate the solvent in the sample without oxygen. Instead of the rotary evaporation instrument, a nitrogen sample concentrator can efficiently concentrate dozens of samples simultaneously.

Latest Ergonomic Features:

  • Elegant appearance with elevated operation panel, embedded flow meter, waterproof button, safe and reliable.
  • Good compatibility, suitable for test tubes (diameter 10 ~ 29mm), conical flasks, and centrifuge tubes, with a sample capacity of 1 ~  50 ml.
  • A free up-and-down needle valve tube with an independent adjustable needle valve controls gas flow at each sample location.
  • Circular turntable structure, 360-degree rotation, convenient sample support into and out of the water bath, easy to operate.
  • 12 positions; each sample position is numbered. spring tube clamp, fixed position.
  • LED real-time displays temperature and time; water bath temperature: RT +5 ̊C  ~ 100 ̊C.
  • All components are made of stainless steel and are anti-corrosion and resistant to organic solvents.
  • When concentrating toxic solvents, the entire system can be placed in a fume hood.
  • Built-in level sensor, anti-dry protection.
