A microcentrifuge is a special type of centrifuge that performs the function of centrifuging samples that are in small capillary tubes, in order to separate the components of these samples into two phases.
This equipment is capable of working with samples that are in liquid or solid state, as well as with liquids of different densities. As the name implies, these kits are small in size and ideal for the needs of clinical laboratories. Despite its size, the microcentrifuge operates at high speed and has interchangeable rotors.
The tubes used in microcentrifuges can range from 0.2 ml to 5 ml. There are several types of microcentrifuges, the most common being the high speed microcentrifuge and the refrigerated high speed microcentrifuge.
The high speed microcentrifuge is mainly used in the areas of hematology, biology, agriculture, biotechnology, microbiology, biochemistry, microchemistry, hepatology, immunology, clinical chemistry, endocrinology, pharmacology and toxicology among others.
How does a microcentrifuge work?
These teams work in the same way as a conventional centrifuge, they only differ in their size, and both manage to separate mixtures composed of solid and liquid elements of different density, exposing them to a rotating force at the intensity that is needed, according to the sample. that is being worked on.
When using the microcentrifuge, it must be taken into consideration that the loads that have the same mass or weight, must be positioned opposite the rotor, in addition to this, they must have the same center of gravity.
What considerations should you keep in mind for the microcentrifuge?
Loading the microcentrifuge in a proper way is very important for its proper operation and preservation. An incorrect loading procedure causes the centrifuge to vibrate during the centrifugation process, which causes the rotor to suffer damage that may lead to its replacement.
A correct loading procedure involves placing the loads on the rotor in a balanced way. Centrifuges are designed to obtain balance when in motion. For this, it is necessary to meet the following requirements:
Position loads so that loads that have the same mass or weight are placed opposite each other on the rotor. If you have an odd number of samples to be loaded, look for another sample of equal weight so as to always form opposite pairs of equal weight; never put an odd number of samples into the centrifuge.
In addition to having the same mass (weight), they must have the same center of gravity, that is: do not place tubes and containers as opposing pairs, which have different shape, size and thickness.
Use the centrifuge by placing all the accessories on the rotor, as this equipment has been designed to work with these.
Use the original equipment rotor and accessories. Non-original parts can cause an imbalance and shorten the useful life of the equipment.
