Turbidimeters are equipment that through optical analysis measure the turbidity of a liquid. That is, they are devices capable of measuring the size and concentration of particles in a suspension by diffusing light at 90 ° in a tube. It can be portable or fixed.

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.

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.

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.

Refrigerators are refrigeration devices used in the medical and scientific sector that are mainly intended for the preservation and storage of reagents, biological samples or medicines. In this Kalstein article, we will see that these appliances have specific characteristics that differentiate them from the refrigerators, or refrigerators, that we have in our homes, and that the functionalities, options and temperature ranges vary depending on the brands and models.
