Welcome to B/R Instruments

We offer spinning band distillation columns and packed distillation columns of various sizes. 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 materials 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 essential oils, flavors, fragrances and natural products. 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 materials 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 the 800 Micro-Distillation Apparatus. This distillation equipment has the most separating power available for samples in the 5 to 25 ml range.

Application notes are available on separating natural product mixtures. We can also provide references for your application or your geographic area. The bibliography section of this website has references from the literature on this subject.
