Freezers and COVID vaccine
A freezer is a refrigeration equipment that comprises a thermally insulated compartment, which helps it to keep cold and thus avoid damage or degradation. It is kept cold by compression or by absorption, which is capable of keeping the products stored inside at a temperature below 0 ° C, normally between -30 ° C and -4 ° C. Although currently some equipment can reach temperatures of -80 ºC. Its function is to maintain, in a controlled environment, various fluids and substances, so that they are kept in good condition, since the lower the temperature, the less chemical and biological activity. To achieve this it is required that the interior temperature of the refrigerator is lower than the ambient temperature.
Electrophoresis and Gel Documentation Systems
Gel electrophoresis is a widely used technique in life science laboratories to separate macromolecules such as DNA, RNA, and proteins. In this technique, molecules are separated according to size and electrical charge.
Incubators, their application in cell and microbiological cultur
The incubators are laboratory equipment that is used to maintain and grow microbiological cultures or cell cultures, regulating viable growth factors such as temperature, humidity and ventilation.
Main applications of a CO2 incubator
A CO2 incubator is a laboratory equipment also called a gasification incubator, where the development of cell and tissue cultures is guaranteed by creating a natural atmosphere. This culture of living organisms in vitro is one of the main applications of CO2 incubators.
What is a humidity incubator?
A humidity incubator is a laboratory equipment that, in addition to controlling the temperature of the indoor environment, also controls the humidity, through a refrigeration system, instead of direct heating. They allow the development of an infinity of experimental work, since with it microbiological and cell cultures can be maintained thanks to its ability to achieve the optimum temperature and humidity for this, as well as the levels of carbon dioxide and oxygen.
Differences between analytical and electronic balance
Balances are instruments whose purpose is to measure masses of bodies in greater or lesser quantity. They are characterized by their accuracy, their precision and their sensitivity. The first quality refers to the property that any physical instrument possesses to supply the result of a measurement with a value coinciding with the true one; this implies that the error is as small as possible.
Laboratory Hoods: Differences
Laboratory hoods are fundamental pieces in the operation of this space to maintain air quality. The variety of hoods in the industry responds to the needs of scientists. Laminar flow hoods, biological safety hoods, and fume hoods all serve a purpose.
What is a microplate reader?
A microplate reader is a specialized spectrophotometer designed to read the results of a technique used to determine the presence of specific antibodies or antigens in a sample. The technique is based on the detection of an immobilized antigen on a solid phase, by means of antibodies that, directly or indirectly, produce a reaction whose product can be read by the spectrophotometer.
How does a natural convection oven work?
A natural convection laboratory oven is one that extracts the air from the environment in which the oven is located. So it transmits heat in a uniform way throughout the equipment creating a natural air circulation.
Processes for water purification
At present there are several equipment for the treatment and filtration of water. The choice of the most suitable one depends on the user’s need, since each one will leave the water adequate for different uses and processes.
