## Abstract

A microtome has a blade holder on which a blade is mounted, an anti-roll device for supporting a section preparation that has been produced by means of the blade, and a suction device by means of which the section preparation can be picked up by suction and carried off. The suction device has a nozzle, with an adjustably mounted nozzle body, and a suction channel. Provision is made that the anti-roll device is mounted on the nozzle body and is adjustable, in particular pivotable, together therewith.

## Claims

### Claim at position 1

1-11. (canceled)

### Claim 12

A microtome having a blade for producing a section preparation, the microtome comprising:
a blade holder to which the blade is mounted;
a suction device, said suction device structured to suction and carry off the section preparation, said suction device having a nozzle with an adjustably mounted nozzle body, said suction device defining a suction channel; and
an anti-roll device for supporting the section preparation produced by the blade, wherein said anti-roll device is mounted on said nozzle body and is adjustable together therewith.

### Claim 13 (depends on 12)

The microtome of claim 12, wherein said nozzle body is mounted pivotably on a pivot bearing.

### Claim 14 (depends on 13)

The microtome of claim 13, wherein said suction channel extends through said pivot bearing.

### Claim 15 (depends on 13)

The microtome of claim 13, wherein said pivot bearing has a recess and a tube part inserted rotatably into said recess.

### Claim 16 (depends on 15)

The microtome of claim 15, wherein said nozzle body is held on said tube part.

### Claim 17 (depends on 12)

The microtome of claim 12, wherein a portion of said suction channel is formed in said nozzle body and is in flow communication with an interior of said tube part.

### Claim 18 (depends on 15)

The microtome of claim 15, wherein said tube part is removable from said recess.

### Claim 19 (depends on 12)

The microtome of claim 12, wherein said anti-roll device is arranged on a side of said nozzle body directed away from said blade.

### Claim 20 (depends on 12)

The microtome of claim 12, further comprising an adjustable finger guard mounted on said anti-roll device.

### Claim 21 (depends on 20)

The microtome of claim 20, wherein said finger guard is formed by a pivotable bow.

### Claim 22 (depends on 20)

The microtome of claim 20, wherein said finger guard has a grip part.
