Do you know what to keep in mind when using your optical microscope?
The microscope is an instrument that allows to observe objects that are not perceptible to the human eye. This is achieved through an optical system composed of lenses, which form and amplify the image of the object being observed.
Laboratory ovens, which one to choose?
Among the wide variety of equipment needed to carry out the numerous activities of a laboratory, we can highlight the use of drying and heating ovens or ovens, basic equipment that is often used quite frequently.
The drying oven: from the simple to the complex
The drying oven is a device used to dry and sterilize glass and metal containers in the laboratory. It is also identified with the name Oven drying. The manufacturers have basically developed two types of oven: those that operate by natural convection and those that operate by forced convection. The ovens operate, in general, between room temperature and 350 ° C.
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.
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?
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.
