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
