BK-2258 Series

Manual Rotary Microtome

These rotary microtomes equipped with imported roller guide rails and high-precision roller screws. This is an ideal device for use in histology due to its ergonomic design, compact structure, high precision, and stable and reliable performance.


* Large-volume removable waste tray on the top of housing, convenient to use.

* Imported cross-roller guide rails andhigh-precision screw motion mechanism.

* Advanced high-precision micro-drive feed system enables stable and high-precision sectioning.

* Small coarse-advance hand-wheel is close to the operator, in accordance with an ergonomic design.

* The precise positioning system is not only easy to use, but also provides accurate X- and Y- axis adjustment.

* Hand-wheel balance is precisely adjusted and locked at any position, ensuring safetyand convenience of sectioning.

* Fast switching between paraffin block clamp and cassette clamp; Paraffin Block Clamp is for Standard Configuration, cassette clam is optional.

* Blade holder can be laterally movedwithout direct contact,enabling use of the entire length of the blade. (three different segments).

* Cassette clamp can be locked at any position along each of the three axes,enabling easy adjustment of the specimen sectioning angle.

* The red bar on the blade holder covers the whole length of blade to protect the user and enables easy changing of the blade.
