What technology do real-time thermo-cyclers use?
A real-time thermo-cycler is a device that simultaneously accurately regulates thermal cycles so that the DNA chains are multiplied by the polymerase chain reaction (PCR), while incorporating a technology that allows the reaction to be tracked. To achieve the latter purpose, the thermocycler is incorporated with a fluorometer, which is made up of an excitation source, absorption filters, a radiation detector and the electronics needed to process electrical signals and transform them into digital signals suitable for computer equipment.
Orbital shakers, functions and parts
Orbital shakers are laboratory equipment used to combine, divide or prepare substances. These equipments create a movement between liquids or between liquids and solids in order to achieve processes of mixing, suspension, dispersion, homogenization, heat transfer, among others.
Laboratory shakers: porcelain or glass dishes
The laboratory shaker are electromechanical devices that are commonly used in specialized chemistry and / or biology laboratories to homogeneously mix solutions and suspensions for tests and trials.
Why is an anesthesia machine necessary in the operating room?
There are 4 types of anesthesia, local, regional, sedation and general anesthesia. The latter is only administered in the case of major surgical interventions, which require a lot of time in the operating room.
What are the advantages of using wheelchairs?
The wheelchair is a technical instrument used by all those who have motor disabilities related to the loss of locomotion, or who have reduced mobility, either as a result of injuries, psychological illness, or physical illness such as paraplegia or quadriplegia, among others. Because this equipment is made of lightweight and resistant materials, the user can fold, lift and store it.
Tips for using water baths in a laboratory
A laboratory water bath is an instrument consisting of a container filled with hot water, used to incubate samples in water at a constant temperature for a long period of time. It is used to incubate samples in water at a constant temperature for a long period of time.
How useful is the veterinary refractometer?
Refraction is the change in the velocity of a wave that affects a surface as it passes from one medium to another with a different refractive index. The refractive index is the ratio of the speed of light in vacuum to the speed of light in another substance, making the refractive index a specific physical property. This parameter of analysis is a good approximation for media where losses by absorption or other phenomena are negligible.
Laboratory water baths: preventive and corrective maintenance
Water baths are equipment that fulfill a function mainly in chemistry laboratories, where they are used to transfer heat indirectly by thermal convection uniformly and constantly to various substances or solids, are divided into general baths and recirculated baths, in this way we can heat liquids or cool them to certain temperatures.
How are Brix degrees measured with the refractometer?
Brix grades are defined as the percentage by weight of a pure sucrose solution, which measures 1 gram of sucrose per 100 grams of sample. The scale is based on the directly proportional relationship between the refractive index at 20°C and the mass percentage of total soluble solids of a pure aqueous solution of sucrose, i.e. 50° Brix equals a sugar content of 50%. This conversion is standardized by the International Commission for Uniform Methods of Sugar Analysis (ICUMSA).
What type of water should be used for a water bath?
Water baths are equipment that allows maintaining a uniform temperature necessary for different tests and laboratory tests; so it depends on these tests, the types of samples and tests to be carried out that you select the type of water you should use; we refer to water type 2, type 1 and type 0, ranging from the required water, water that has certain conditions and definitely the water not suitable for this kind of equipment.
