Histology - Advanced Rotatory Microtome

The microtome is an instrument designed to make fine and precise cuts of biological materials, such as tissues and samples, in order to prepare thin sections for observation and study under the microscope. These cuts, called sections, are extremely thin, making them ideal for preparing samples.

The Nahita brand manual rotatory microtome is an advanced model with a crank advancement system, specifically designed for cutting plant or animal tissues embedded in paraffin or harder materials. This equipment is ideal for both routine histological applications and research conducted in laboratories, universities, and various fields such as biology, medicine, and industry, among others.

The model's design includes a robust housing and a wide base that provides stability to the equipment.

The wheel provides dual security mechanism:

A locking lever that locks the sample or blade holder arm in the upper limit position to facilitate sample or blade changes, acting as a protection and safety system for the user.

A locking system through a lever located on the side base that allows fixing the wheel in any position.

The wheel allows moving the base of the blade holder forward, backward, and laterally to place it in the most suitable and precise position. It can also vary the blade orientation angle: from 0 to 12°. This means that the blade can be tilted from a completely horizontal position to an inclined position with respect to the sample.

The adjustment of the blade orientation angle is important to optimize the quality of histological cuts. By changing the angle of the blade, the cutting process can be adapted, and the precision of the obtained sections can be improved. Depending on the hardness and characteristics of the sample material, as well as the type of subsequent analysis, the blade orientation angle may vary to achieve the best results.

At the end of the sample's journey, when using the cutting crank, an alarm sounds as a warning.

The crank allows moving the sample clamp back to its initial position. The clamp with an orientation system ensures that the cutting edge is in the exact and precise orientation of the sample surface.

Adjustable cutting thickness from 0.5 to 60 microns. The cutting thickness can be adjusted in specific increments: 0.5 microns (steps of 0.5 to 2 microns), 1 micron (steps of 2 to 10 microns), 2 microns (steps of 10 to 20 microns), and 5 microns (steps of 20 to 60 microns). 1 micron is one thousandth of a millimetre: 1 µm = 0.001 mm.

The blade holder is for standard blades.

The equipment includes two blade holders: one for disposable high-profile blades and another for disposable low-profile blades; both have a foldable finger protector to cover the blade during work breaks.

It is supplied with a standard clamp and a universal clamp for cassettes, which can be easily interchanged.

The analogue counting screen shows the number of cuts made (from 1 to 99) and has a black reset button for a new count.
