B/R Instrument offers a variety of equipment for purifying dueterated solvents. Dueterated solvents can become contaminated when used for NMR or other experimental procedures. Being very expensive, these solvents are worth recovering and in many cases the dueterated solvent can be separated from the contaminants. The purified material can be reused creating significant cost savings.
We offer spinning band distillation columns and packed distillation columns of various sizes for dueterated solvent purification. Fully automatic and manually operated models are available. Boiling flask sizes range from 10ml to 50 liters and the number of theoretical plates range from 15 to 200.
For purification of dueterated solvents in the 1 to 50 liter range, the 9600 Fractional Distillation Apparatus is ideal. It is a high efficiency fractional distillation system capable of purifying dueterated solvents. The very low "hold up" means that the minimum amount of the valuable material is left behind in the distillation column after purification is complete. The microprocessor controller automates the fractional distillation, minimizing the need for operator attention.
For purification of dueterated solvents in the 25 ml to 1 liter range, the 36-100 Mini Fractional Distillation Apparatus is recommended. This distillation apparatus has all the advantages of the 9600 distillation system with 4 times the separating power.
For really small samples, consider our 800 Micro-Distillation Apparatus. This distillation equipment has the most separating power available for samples in the 5 to 25 ml range.
