Frequently
Asked Questions
How do
I choose a distillation system for my application?
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 |

What is the difference between spinning band distillation
and packed column distillation?
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.
Is it time consuming to recycle solvents?
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.
What range of automation is available for B/R distillation systems?
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.
What range of volumes can B/R's distillation system handle?
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.
What is the range of theoretical plates for the distillation
columns made by B/R?
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.
What types of applications can this distillation equipment be used for?
There are
many applications including the following:
