Reverse osmosis: Recommendations and care
Reverse osmosis is a technology for water purification, where a semi-permeable membrane is used to remove minerals and ions from the water, and remove larger particles from the water.
Ice makers: Recommendations and care
Ice makers are machines that make ice from moving water, as opposed to the traditional method of making ice, where the water is frozen. They are very useful equipment in the health and research sector, so it is essential to carry out proper maintenance and follow a series of steps to care for them.
Steps to use an analytical balance
The analytical balance is a measuring instrument that has a high degree of precision, but which in turn requires experience and skill from the operator. Its creator was the Scottish chemist Joseph Black in the year 1750, from there this type of balance has become an important scientific instrument to obtain accurate measurements.
Chillers, a water bath and a circulation bath
A chillers is a laboratory equipment used to remove heat from a product or process. This equipment acts as a heat exchanger, in other words, it cools using a contact surface through which the hot material passes. In the past, laboratories used cold water, ice, dry ice, or liquid nitrogen for cooling.
How does a refractometer work?
Refractometers are optical instruments that allow determining the percentage of soluble solids in a liquid solution, making use of the principle of total refraction of light (caused by the type and concentration of substances dissolved in a liquid solution), which takes place in the boundary layer between the prism and the sample.
Freeze Dryer: What is it? What is it for?
A lyophilizer is an equipment that allows to carry out lyophilization, that is, it is an instrument that serves to remove moisture from a product by drying it cold, thus obtaining a dehydrated product that can be rehydrated again when needed, recovering completely its properties at the time of use.
What is a fluorescence gel photo documentation system?
A gel photo documentation system is a composite system used to observe, take photos and analyze the bands of the gels obtained from electrophoretic runs. These systems are designed to allow obtaining sharp, high-quality images, offering better analysis, and providing a results backup system, which is essential when publishing the results of an investigation.
Laboratory refrigerators and freezers, temperature ranges
A laboratory refrigerator is a piece of equipment that allows to efficiently conserve all kinds of substances that are cooled in it, whether they are liquid, solid or homogeneous substances. Reason why it is considered essential equipment within the laboratory.
Reverse osmosis and water purification
The purification of drinking water consists of a series of steps to which the water is subjected to eliminate waste (solid and mineral) and microorganisms from it in order to obtain water of greater purity and better quality for the consumer.
Uses in a laboratory of the “Ice Maker”
An ice maker is a machine for making ice. This machine produces the ice from moving water, the difference from the traditional method of making ice, where the water is frozen. This principle results in the air being removed, as well as the suspended solids.
