Types of micropipettes
Micropipettes are very precise measuring instruments for handling aqueous solutions. Within this type of micropipettes we can differentiate the manually operated (analog) and the electronic ones. Although both types of pipettes work with the air chamber pipetting system, they present certain differences in terms of format and mode of use.
What is it? and How is it used? a spectrophotometer
A spectrophotometer is a piece of equipment that measures how much light a substance absorbs. Its efficiency, resolution, sensitivity and spectral range will depend on the design variables and the selection of the optical components that comprise it. Spectrophotometry is the quantitative measurement of the transmission properties of a material based on the light wave.
How do you prepare a homogenate?
The crude mixture of destroyed cells is known as the homogenate. During the centrifugation of a cell homogenate, larger particles sediment faster than small ones, which makes it possible to obtain crude organelle fractions by means of differential centrifugation.
Thermal Cycler: Real Time PCR
The thermal cycler is a device that allows the polymerase chain reaction (PCR) efficiently and quickly; by means of the automatic and cyclical realization of the temperature changes that are required for the amplification of a deoxyribonucleic acid (DNA) chain; from a thermostable enzyme.
Balance – precision and accuracy
The balance is a piece of equipment that measures the mass of a specific body, providing accurate data about its weight. Among the many existing models, the analytical balance that has a high power of rigor stands out, since with it great precision can be obtained.
How does a laminar flow cabin work?
A laminar flow cabin is a laboratory equipment that provides an area delimited by easy-to-clean surfaces and disinfect with a filtered air flow through prefilters, which are responsible for retaining the largest particles that are present in the air, and by HEPA filters (High Efficiency Particulate AIR), which are high efficiency filters capable of retaining particles up to 0.3 μm with a minimum efficiency of 99.97% providing clean and constant air at a speed of 0.3 to 0, 5 meters per second .. That is, this type of equipment is employed in processes where the contamination control is needed.
How does a thermal cycler work?
A thermal cycler is a Molecular Biology Laboratory Equipment, used in the amplification of DNA molecules by the PCR technique (polymerase chain reaction), because it is capable of performing temperature cycles necessary for amplifying The DNA strands.
What is an Ecological Microscope?
The microscope is an instrument that increases the size of an image and allows you to see more details than would be possible to see with the naked eye. There is a wide variety of microscopes, of which the ecological microscope is of relevance.
Cooling baths and circulation baths
The use of cooling baths and circulation baths in research laboratories is of great importance, since both allow experiments to be carried out where the uniformity of the temperature in the sample is considered key and the objectives set by such are achieved.
Laboratory water systems: types of waters
The quality of the water in the laboratory is one of the main concerns of those trying to carry out accurate and efficient experiments. The overall water purification process involves not only the final ultra-purification stage, but also a pre-treatment stage.
