3-11 KNIFE CARRIERS

Hazard of hand injuries:

Due to moving parts in connection also

with the microtome knife, a danger

area arises, which might lead to hand

injuries in case of non-compliance with the safety

features of the microtome and when disregarding

the instruction manual.

The knife carriers of the microtome are easy to

use, can be moved sideways and are equipped

with knife guards for user safety while adjusting

knife and specimen.

3-11-1 DISPOSABLE BLADE CARRIER ER

The disposable blade carrier ER is designed to

take all commercially available high and low profile

blades.

Using low profile blades:

• Insert the blade into the slot behind the

clamping plate (fig. 42.5).

• For this, turn the clamping lever (fig. 42.7)

towards the front. Swing the bracket with scale

(fig. 42.4) to the front.

• Loosen the clamping lever (fig. 42.7) and, if

necessary, slightly push the lower part of the

clamping plate (fig. 42.5) as well.

• Insert the blade on the rail (fig. 42.3) and push

it from the side to the middle.

• Afterwards, return the clamping lever (fig. 42.7)

upright, thus locking the blade in position.

• The bracket (fig. 42.4) is provided with a scale.

• After loosening the clamping lever (fig. 42.2)

and after having moved the bracket (fig. 42.4)

upwards, move the blade together with the

entire upper part without having to loosen the

blade clamping.

• This way, the entire cutting length of the blade

can be used.

• Then tighten the clamping lever (fig. 42.2).

• The lever (fig. 42.2) can be removed by pulling

it off towards the side.
