6.2.4 Universal cassette clamp
Prior to sectioning, laboratory personnel
MUST check that the cassette is seat-
ed securely in the universal cassette
clamp.
Leica / Surgipath cassettes with minimum dimensions of 39.8 x 28 mm and maximum
dimensions of 40.9 x 28.8 mm may be clamped in the universal cassette clamp (UCC)
horizontally as well as vertically.
When using other – particularly thin-walled – cassettes, the cassette may become de-
formed or other problems may arise with the clamping system. If the user tries clamp-
ing the cassette and realizes that it is not securely clamped into place, an alternative
tensioning clamp must be used.
When using cassettes whose lid is molded on, make sure that the broken edge left by
removing the lid does not prevent the specimen from being securely clamped – if nec-
essary, the specimen must be clamped horizontally.
Before clamping the cassette into the universal cassette clamp, remove excess wax on
the outside of the cassette to ensure that the cassette clamps in securely.
Wax deposits on the outside of the cassette can make the universal cassette clamp
dirty. The dirt prevents the cassette from clamping in securely and can lead to sections
being too thick or thin, chattering within the section and, in the worst-case scenario,
damage to the specimen. Prior to sectioning, the user has to verify that the specimen
is clamped securely and, if necessary, remove wax deposits from the universal cas-
sette clamp according to the specifications in Chapter 8.1 "Cleaning and maintenance
– Universal cassette clamp".
