Pathological Anatomy

Pathological anatomy is the science that studies the pathophysiological and morphological alterations of the disease. It studies disease at the organic, tissue, cellular, subcellular, and molecular levels. 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, the cells of the tumors and tissues of the organism 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 tissue from 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.


Types of pathology instruments that a laboratory may need

Water Baths

They are a very common element in any type of microbiological laboratory. This type of equipment is a container that is capable of containing hot water to incubate samples in water at a constant temperature for a long period of time. Water baths generally have an interface that allows the user to set the proper temperature to achieve the desired results. This model is no exception.

Among its uses, you can find heating of reagents, fusion of substrates or incubation of cell cultures. There are some recommendations when it comes to the use of water baths. First, experts do not recommend using the water bath with pyrophoric or moisture-sensitive reactions. Second, you need to constantly monitor the water level and only use distilled water; the reason is that you don't want salts to deposit on the heater.


Bacti-Cinerator Sterilizer

The bacti-cinerator sterilizer sterilizes microorganisms using infrared heat produced by a central ceramic element. The ceramic element does not contain asbestos and guarantees maximum sterility without splashing on the work surface. Complete sterilization occurs within 5-7 seconds at the optimum sterilization temperature of 1500ºF (815.6ºC). The small size makes the bacti-cinerator sterilizer an ideal instrument for anaerobic and aerobic chambers

Various easy-to-use accessories are also available for the bacti-cinerator sterilizer.
YR053254 and YR053255 are our company's new products for bacti-cinerator sterilizer. The angle of the heater will be changed, and it is very convenient to sterilize the big flask, bottle, etc. Sterilizes needles, loops and culture tube ends in five to seven seconds at an optimal sterilization temperature of 815.6°C (1500 °F)

How to use a Histopathology Cooling Plate?

At Kalstein we tell you how with the YR440 model, the cooling process is a fundamental step in any histology laboratory, since it is a fundamental procedure for making good quality paraffin block sections. It is almost impossible to make good cuts without doing the cooling process. Using the cooling plates to chill the paraffin blocks creates a drastic improvement and makes cutting much easier.

These facts speed up the process and help save time for lab operators. An interesting fact about this process is that the cold wax allows the operator to make thinner sections, which will be achieved by supporting the harder elements within the tissue sample. You may be wondering why cooling the paraffin blocks makes the process easier. Well, it turns out that when a small amount of moisture from melting ice gets into the block.

How to install and operate a manual microtome?

The Kalstein Rotary Microtome has many great features that make it the ideal item to keep in your histology lab. The streamlined casing not only enhances the appearance, but also makes the cleaning process easier without opening the casing. This model uses imported cross roller guide rails and a screw moving mechanism to ensure precision resulting in superior cutting performance.

Its advanced high-precision micro-drive feeding system allows for uniform and high-precision cutting. This model has a hand wheel that rotates based on a mechanical balance mechanism and can be locked in any position, providing the highest level of safety and comfort. The cassette holder can be locked in any position along each of the three axes, allowing easy adjustment of the specimen cutting angle.
