4 .3 Crystal rack

The crystal rack a is fixed onto the heating
plate and operates as a heat transition between
the heating plate and the sample tubes. It com-
prises 6 or 12 glass cylinders accommodated
circularly to provide full supervision. A level
indication designates the optimal filling level for
water, which serves as the heating medium.
A further advantage of the crystal rack com-
pared to the widely used metal racks is the
compatibility with all kind of sample tubes differ-
ing in shape, diameter and length.
