Tetrahydrofuran is used to dissolve polymers for molecular weight analysis by GPC (Gel Permeation Chromatography).
Average molecular weight is an important property of polymers and is an indication of strength and flexibility.
After use, the waste THF is contaminated with:
- Polymer fragments
- Other solvents
Boiling Point: 66 °C
The 9600-90 is a good choice for recycling THF waste.
Key features are:
- All glass and Teflon contact surfaces.
- High efficiency distillation. Get back HPLC grade THF
- Completely automatic. Push start and walk away.
- Safe! CE marked ETL listed
