Welcome to B/R Instruments

There are many considerations when choosing a distillation system. These include:

• Volume of sample to be distilled
• Difference in boiling points of chemicals to be separated
• Desired Purity of the distilled material

All distillations attempt to separate a lower boiling material from a higher boiling material. Packed columns are "packed" with a material that creates a large surface area within the distillation column. Vapors rise through the column and are condensed by the condenser. The descending condensate "wets" the packing. Ascending vapors rise through the wet packing and are forced into intimate contact with the condensate. This intimate contact causes the vapor to become enriched in the lower boiling material. This process is often call rectification.

Spinning band distillation creates intimate contact between the vapors and the condensate in a completely different way. It uses a helix rotating at high speeds inside the distillation column. The rotating band forces vapors into intimate contact with the condensate on the wall of the distillation column. This contact takes place in a very thin layer that is refreshed thousands of times per minute. As a result, spinning band distillation gives a very large number of theoretical plates in a fairly short distillation column.

No! Solvent recycling is highly automated with B/R's solvent recycling systems. It only takes a few minutes each day to operate the equipment and manage the waste streams.

We offer manual, semi-automatic and fully automatic distillation systems. This range of automation allows the customer to choose a system that fits their needs and their budget.

Our range of distillation systems can handle samples as small as 5 mls, as large as 200 liters and a wide variety of pot sizes in between.

We have columns with as little as 1 theoretical plate and as many as 200 theoretical plates. The 200 theoretical plate column (36-100) is capable of separating materials that boil as close together as 0.5 C.
