Gel Cassettes
Figure 3. DALT gel
cassettes
The DALT gel cassettes are pre-assembled. Two glass plates are held together along one
edge by a strip of silicone rubber, and the glass spacers (1.5 or 1.0 mm thick) are glued
in position. To complete assembly, close the two plates like a book. Gels are removed by
opening the book after the run and lifting out the slab. The cassette is easily cleaned as a
unit, and can be stood upright in the open to dry. The cassettes are dishwasher-safe.
Cassettes are 20.4

The DALT Gel Caster holds up to 25 gel cassettes, 1 mm thick, or up to 23 cassettes,
