Laboratory - Term Overview

Home | Blog | Laboratory - Term Overview

A laboratory is a place that is equipped with the necessary means to carry out experiments, research or work of a scientific or technical nature. In these spaces, the environmental conditions are controlled and normalized to avoid the occurrence of influences outside those foreseen, with the consequent alteration of the measurements, and to allow the tests to be repeatable.

Among the conditions that a laboratory tries to control and normalize are atmospheric pressure (to prevent the entry or exit of contaminated air), humidity (it is a matter of reducing it to a minimum to avoid the oxidation of the instruments) and the level of vibrations (to prevent measurements from being altered)

There are different types of laboratory:

- Chemical laboratories study compounds and mixtures of elements to test theories of science. Lighters, stirrers, decanting ampoules, distillation flasks, crystallizers, pipettes and test tubes are some of the instruments used in this field;
- Biology laboratories, for their part, work with biological materials at all levels ( cells, organs, systems ). Microscopes, thermometers, and surgical equipment help scientists to carry out their activities;
- Clinical laboratories are those where experts in clinical diagnosis develop the analyzes that contribute to the study, prevention, diagnosis and treatment of health problems.

In a broader sense, the notion of laboratory refers to any place or reality in which something is made or experienced. In this way, one can speak of a language laboratory to name the teaching center where students learn and practice foreign languages.

Laboratory tests with animals

The use of non-human animals to perform laboratory experiments is known as vivisection, and this represents one of the most controversial faces of science. It's a practice that occurs not only in the medical sciences, but also in the beauty, military, tobacco and chemical industries in general. Tortures by humans towards the rest of the species seem to know no limits.

The term "guinea pig" has its origin in the 16th century, a time in which man began to use the rest of the animals to explore the mysteries of our physiology, as well as to evaluate the effects of innumerable substances and medicines, without forgetting of poisons, and of various industrial processes. Individuals of various species, from primates to dogs, have died and continue to be killed so that humans can quench their thirst for superiority and their absurd need to prolong life.

The main objective of laboratory experiments with animals is to carry out toxicity tests, including dermal and oral toxicity tests, immersion, injection and inhalation studies and the Draize test. Mercy, compassion and consideration aren't present when so many innocent beings are subjected to lethal doses of substances of all kinds or tests of resistance to lack of gravity; it's a show of cowardice and an absolute lack of sensitivity that takes place every day, in all parts of the world.

Thanks to covert operations, various animal defense groups have managed to expose the terrible torture that many laboratories carry out behind closed doors. This has led many researchers to avoid animal testing, at least not to be embroiled in a public scandal.

No one will be able to give back to the millions of innocent victims their lives; But science has shown that there are methods that don't use other living beings to test new substances, and therefore there is no excuse to continue with this massacre.
