2-10 SPECIMEN CLAMPING

To clamp specimens, different specimen clamping

systems are available. With the orienting adapter it

is simple to align the specimen properly in relation

to the knife.

2-10-1 UNIVERSAL CASSETTE CLAMP

The universal cassette clamp (fig. 7) represents a

quick change system.

Fig. 7

To insert or remove the cassette from between the

fixed (fig. 7.1) and movable (fig. 7.2) jaws, pull the

lever (fig. 7.3) to the front.

CAUTION! To achieve an optimal clamping keep

the locating surface of the cassette free of

paraffin.

2-10-2 STANDARD SPECIMEN CLAMP

The standard specimen clamp (fig. 8) is used for

rectangular and square paraffin and plastic blocks.

Fig. 8

Insert the specimen against the fixed jaw (fig. 8.2)

first. Then turn the knob (fig. 8.3) to tighten the jaw

(fig. 8.1). Fig. 8.4 and 8.5 show the orienting

adapter (see 2-11-2, adapter, orienting, specimen

orientation), fig. 8.6 indicates the four holes for the

fastening screws.

NOTE! For the stability of the specimen, do not let

it project over the clamping jaws too much.

The standard specimen clamp is supplied with two

movable jaws, which are different in weight.

The lightweight jaw is used in addition with inserts

for round specimens.

The heavier jaw is intended to be used together

with the standard specimen clamp with no other

holding elements.

To exchange the clamping jaw, unscrew the

clamping screw (fig. 8.3) to remove the jaw and

replace it with the other one.
