The main objective of pathological anatomy is not only to study the evolution and causes of a disease, but also to make a prognosis of the effects that different diseases can have on human beings. To do this, tumor cells and body tissues are analyzed.
Thus, within pathological and cytodiagnostic studies, two types of tests are differentiated: pathological and diagnostic. In the first of them, a sample of the tissue of any organ is analyzed with the intention of identifying the type of cell and what treatments would be useful to combat the alteration. As for diagnostic tests, they are also known as biopsy and their main objective is to obtain a sample of organic fluid or tissue to study the existence of a disease, with the intention of determining a specific diagnosis.
Among the equipment most used in this science, we have: microtomes, microscopes, tissue processor, water baths for tissues, cryostats, cooling plates, trimmer and paraffin dispenser, slide dryers, tissue inclusion systems, systems of automatic staining for slides, among others.

This is a very common type of microtome. It works with a staggered rotary action so that the actual cut is part of the rotary motion. In a rotary microtome, the blade is typically set in a horizontal position. This microtome is the perfect choice for you if you are looking for a standard rotary type.
In the daily routine within a laboratory, microscopic substances and samples are very common. Most of the time it is necessary to cut some of the samples into extremely thin slices of material, known as sections. To prepare a sample and make these types of cuts, it is necessary to have a microtome, a very essential device in the field of microscopy. The use of microtomes allows the preparation of samples for observation under transmitted light or electron radiation.
Microtomy is a method for the preparation of thin sections for materials such as bones, minerals and teeth, and an alternative to electric polishing and ion milling. The microtome sections can be made thin enough to section a human hair across its width. You should know that the model we offer you is a high-end device that will give you the results you need to achieve the exact sample cuts.

Characteristics:
The value of the histological examination in the diagnosis and classification of clinical conditions is entrusted to the experience of the pathological anatomy laboratory in handling the wide range of specimen types submitted for analysis.
From receipt of the tissue sample to presentation of the slide for microscopic examination, histologists must consider the composition of the specimen to determine how it should be handled effectively.
Most samples follow a routine cycle of dehydration and wax embedding with paraffin for the purpose of sectioning on the microtome. However, due to its high calcium content, bone is a particularly difficult tissue to section and the density of the sample must be taken into consideration. Cutting decalcified sections of bone requires embedding in a resin, a specialized microtome, and modified staining techniques.
Consequently, most laboratories decalcify bone samples, allowing them to be embedded in paraffin and processed. Nitric acid and formic acid are used as decalcification agents, with formic acid being more suitable for laboratories performing molecular analysis, because unlike nitric acid, it does not destroy DNA.
.
On many occasions, manual sectioning is recommended for paraffin-embedded specimens due to the need to vary the levels of force used to cut various parts of the sample.
Tissues common to analysis, on the other hand, sometimes require larger and thicker sections. As a consequence, these samples sometimes require casting in resin with the use of a fully mechanized microtome that slowly applies force in a constant and controlled manner to thereby generate sections of good quality.
At Kalstein we offer you a wide range of innovative microtomes and pathological anatomy equipment such as specialized bath for histology, paraffin dispensers, cooling plates, tissue processing machines, paraffin inclusion stations. That is why we invite you to take a look at the “Products” menu.
