How does a fume hood work?

A hood or hood in laboratories are an effective means of capturing flammable, irritant, corrosive, carcinogenic vapors, etc. to prevent personnel exposures and avoid their dissemination in the laboratory atmosphere. When the hatch is down, the cab is also a physical barrier that protects the operator from hazards such as splashes, aerosols, fires, and minor explosions.

Care and correct use of balances

The balances are instruments that are used to measure the mass of a body or also the weight of it. Its origins lie more than 3,500 years before Christ, in Egypt. The scales differ from each other by the design, the principles used and the metrology criteria they use. At present, it could be considered that there are two large groups: mechanical scales and electronic scales.

Electrosurgery, what is it and how does it work?

The electrosurgery unit, or electrosurgery, is a medical device that uses electrical phenomena to produce heat; Its objective is to coagulate, fulgurate, desiccate or cut tissues, depending on the established parameters. Heat production is achieved through the passage of an oscillatory electric current, concentrated in a small area. The smaller the space in which the current flows, the greater the energy density at this point, which causes increasing temperatures.

Surgical navigation systems, heading to the operating room of the future

The most recent advances in digital medical technology achieved this year allow surgeons to reach new levels of accuracy and safety. From now on, navigation systems evolve more and more, they are expanded and assisted by computer, advances in software, instruments and images facilitate the diagnosis, planning and execution of procedures.
