HCS Glass Reactor System

HCS Glass Reactor System

Our glass reactor is manufactured from borosilicate 3.3 glass tubing. Complemented with other highly corrosion-resistant materials such as PTFE and Viton. HCS Glass Reactor Series has a high durability over a long period of time.

Borosilicate Glass is widely used for laboratory glassware. It has excellent thermal properties with its low coefficient of expansion and high softening point. It also offers a high level of resistance from water, acids, salt solutions, organic solvents and halogens.

Application of Glass Reactor

  • Vacuum Distillation
  • Multi-component reactions
  • Gas introduction into liquid phase
  • Extraction of multi-phase mixture
  • Crystallization
  • Reflux
  • Multiple chemical reactions liquid/liquid, liquid/solid
  • Low temperature chemistry
  • Cell Culture

Advantages of Borosilicate 3.3 Glass Tubing

  • Wide operation temperature range
  • High heat resistance
  • Very low thermal expansion (linear over a wide temperature range)
  • Hydrophobic characteristic makes cleaning easier
  • Against chemical aggressions
  • Non-flammable
  • High optical translucency
