Vortex: is it a mixer, shaker or agitator?
Un vórtex es un tipo de agitador también llamado mezclador de vórtice, éste es un dispositivo simple que se usa comúnmente en los laboratorios para agitar pequeños tubos o frascos de líquido. Se compone de un motor eléctrico con el eje de transmisión orientado verticalmente y unido a un trozo de goma o caucho montado en forma de copa, ligeramente excéntrico.
Electrophoresis Run Power Sources
Electrophoresis in agarose or polyacrylamide gels is one of the methodologies most used in the laboratory in everything related to working with nucleic acids. The principle of electrophoresis consists in the migration of the molecules through a gel or another type of matrix of porous nature, in which, by the action of an electric field, they will be separated according to their size or molecular weight, this is achieved thanks to the action of a power source for electrophoresis, key equipment for the proper execution of this technique.
Refractometer: What do they measure?
The refractometer is an optical device that serves to measure the percentage of soluble solids in a liquid solution, this instrument uses the physical principle of total refraction of light, which originates from the concentration and type of substance dissolved in a liquid solution.
Ice maker: capacities
An ice maker is a device where water is poured into a tray that has a specific format to shape the ice that you want to create.
The tray freezes slowly and gradually in layers until the water freezes completely and creates the ice cubes. Once the correct temperature is reached, the tray heats up enough to allow the cubes to separate. The cubes are deposited in the storage tank.
Electrophoresis Power Source
Electrophoresis is a basic method in the field of molecular biology for the analysis (separation, purification, preparation) of nucleic acids and proteins. The principle of electrophoresis consists in the migration of the molecules through a gel or another type of matrix of a porous nature, in which, by the action of an electric field, they will be separated according to their size or molecular weight, this is achieved thanks to the action of a power source for electrophoresis.
Electrophoresis: what are the necessary reagents?
Electrophoresis is an analytical technique in which a controlled electric current is used in order to separate biomolecules according to their size to electric charge ratio, using a gelatinous matrix as a base.
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.
Laboratory balances: kilos, grams, micrograms
Mass is one of the quantities that needs to be evaluated in the laboratory, either to prepare reagent solutions, specimens or samples for a given analysis, with the accuracy and precision required by the quality of the study to be carried out.
What is a laboratory refractometer?
Refractometers are optical instruments used to determine the percentage of soluble solids in a liquid solution. For this, the refractometer makes use of the principle of total refraction of light (originated by the type and concentration of the substances dissolved in a liquid solution, for example, sugar), which takes place in the boundary layer between the prism and the sample.
Dental autoclaves: types and uses
An autoclave is a piece of equipment for medical and dental use that is used to sterilize using steam at high pressure and temperature. This device consists of a thick-walled metal container and hermetic closure, which allows high pressure sterilization, ensuring maximum disinfection of all clinical and dental materials.
