Drying ovens or ovens: Are they sterilizers?
The oven or also called drying oven is a piece of equipment used to dry and sterilize glass and metal containers. It achieves this, thanks to the fact that inside the temperature is higher than in the environment. According to its mode of operation, there are basically two types of oven: those that operate by natural convection and those that operate by forced convection.
How does a blood chemistry analyzer work?
A blood chemistry analyzer is an instrument that performs biochemical assays on clinical samples such as blood serum, plasma, urine, and cerebrospinal fluid and other biological fluids to detect the presence of analytes related to body metabolism, disease, or drugs. These kits are used in a variety of institutions, including small clinics, research laboratories, and large clinical laboratories.
Visible and UV Spectrophotometer: Differences
A spectrophotometer is an instrument that measures how much light a substance absorbs. This equipment measures the amount of absorbance after light passes through a solution. Each substance transmits, reflects, and absorbs light slightly differently. In chemistry, spectrophotometry is the quantitative measurement of the transmission properties of a material based on the light wave.
Freeze Dryer: What is it? What is it for?
A lyophilizer is an equipment that allows to carry out lyophilization, that is, it is an instrument that serves to remove moisture from a product by drying it cold, thus obtaining a dehydrated product that can be rehydrated again when needed, recovering completely its properties at the time of use.
How does a pH meter work?
A pH meter or pH meter is an instrument used to measure the acidity or alkalinity of a solution. The information provided by this equipment expresses the degree of acidity of an acid or a base in terms of the activity of the hydrogen ions.
What is two-dimensional electrophoresis?
In this technique the proteins are separated sequentially by two physical criteria. First, the proteins are separated on a gel with a pH gradient in a denaturing environment according to their isoelectric point (isoelectric focusing). After this charge separation, the proteins are separated according to their molecular mass or size by discontinuous polyacrylamide gel electrophoresis in the presence of SDS (SDS-PAGE).
PCR and COVID techniques
The polymerase chain reaction popularly known as PCR, is a Molecular Biology technique, widely used today, in the clinical and scientific field, because it allows the amplification of DNA fragments, starting from a very small amount of this biomolecule.
Laminar flow hoods: What are the best known brands?
A laminar flow hood is a highly specialized laboratory equipment that provides a sterile and safe area or zone within the laboratory, to carry out any activity that is required. This equipment constitutes a space with a specific air treatment, which provides an area with a strict control of non-road particles.
Laboratory refrigerators and freezers, temperature ranges
A laboratory refrigerator is a piece of equipment that allows to efficiently conserve all kinds of substances that are cooled in it, whether they are liquid, solid or homogeneous substances. Reason why it is considered essential equipment within the laboratory.
What is a laboratory magnetic stirrer?
A magnetic stirrer is laboratory equipment that uses a rotating magnetic field to mix one or more solutes with a solvent in an automated way. It is considered the most widely used type of stirrer, since it is silent, efficient and does not have direct contact with the sample.
