How to keep your spectrophotometer in good condition?
The spectrophotometer is one of the main diagnostic and research instruments developed by humans. It is used in the laboratory in order to determine the concentration of a substance in a solution, thus allowing quantitative analysis.
The Centrifuge: an Essential Element
A centrifuge is an apparatus that applies a sustained centrifugal force (that is, a force produced by rotation) to impel matter out of the center of rotation. This principle is used to separate particles in a liquid medium by sedimentation. In general, the centrifuge is used in laboratories as a process of separating the sedimentation of liquid and solid components.
Horizontal autoclaves vs. vertical
Laboratory sterilization has its own requirements. The choice of the right autoclave depends on different factors: the diversity of the load, the frequency of use, available services and the volumes of the loads.
Autoclaves are essential equipment for almost any type of laboratory since the sterilization process is carried out through them, so it is essential to choose the best and the one that best suits your needs, since autoclaves come in many forms and sizes from compact and portable to recessed wall units, and many configurations from horizontal front loading autoclaves to vertical top loading autoclaves
What is laminar flow hood?
A laminar flow hood is a device that allows obtaining a sterile and safe area for any need that is required within a laboratory. It can be: horizontal or vertical. Basically it constitutes a space, which, by means of a specific treatment of the air, allows to work in an area with a strict control of non-road particles
Common Mistakes When Using an Electronic Balance
Electronic balances are highly valued measuring equipment for chemical, analytical and formulation operations in quality industries and laboratories. They are used, like scales in general, to measure the mass of a body or substance, only that as this is a precision balance, the measurement is exact.
Do you know how an analytical balance works?
The balance is a laboratory instrument that measures the mass of a body or chemical substance, using the force of gravity acting on the body as a means of comparison. The word comes from the Latin terms:
bis which means two
linx which means dish.
It should be taken into account that weight is the force that the gravitational field exerts on the mass of a body, such force being the product of the mass by the local acceleration of gravity. [F = m x g]. The local term is included to emphasize that the acceleration depends on factors such as geographical latitude, height above sea level and land density, at the place where the measurement is made. This force is measured in Newton. Did you know? The balance has other names, including scales and scales.
What applications do refrigerators have in the healthcare sector?
The refrigerator is an equipment whose function is to maintain, in a controlled environment (refrigerated space), various fluids and substances, so that they are kept in good condition. The lower the temperature, the less chemical and biological activity.
Two main types of refrigerators are distinguished in the health sector: laboratory refrigerators and pharmacy refrigerators. Both must allow easy and complete cleaning of surfaces and must offer high reliability, especially with regard to temperature control. Some models also offer an automatic defrost and / or forced air cooling function.
How does an autoclave work?
Moist heat destroys microorganisms by coagulation of their cellular proteins. The main sterilization method using moist heat is pressure steam sterilization. There are also other decontamination methods that use this type of heat which, although they do not allow the total destruction of microorganisms, reduce the microbial load of a material.
Tissue processing for histological studies
issue processing is a very important part of any histology laboratory, and begins with obtaining the tissue under study. In the case of plant tissues, samples of the different organs that make up the body of the plant are taken directly, while human and animal tissues can be obtained in different ways through biopsies (excisional, incisional, endoscopic, colposcopic, etc. .) and by autopsy / autopsy.
Tissue water bath
Water baths are a very common element in any type of microbiological laboratory. This type of equipment is a container that is able to retain hot water to incubate samples in water at a constant temperature for a prolonged period. Water baths generally have an interface that allows the user to set the correct temperature to achieve the desired results.
