Jepson Bolton's International Catalogue
A robust, precision instrument suitable for virtually all types of fraction
collection and capable of functioning equally well either as a stand
alone unit or as the principal module in Buchi Chromatography systems.
The collection process is on an elapsed time basis which can be preset
from 1 second to 999 minutes per fraction. Three types of tube racks
(supplied separately) are available for 20ml, 50ml and 250ml tubes
respectively. A distribution plate is also available for collecting fractions
of unlimited size. A three-way solenoid valve is employed to divert flow
to waste during changeover.
