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 prevent influences other than those expected from occurring, 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 avoid the entry or exit of contaminated air), humidity (it is about reducing it to a minimum to avoid oxidation of the instruments) and the level of vibrations. (to prevent measurements from being altered)
Laboratory types
There are various types of laboratories:
* Chemical laboratories study compounds and mixtures of elements to test the theories of science . Burners, 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 carry out their activities;
* clinical laboratories are those where clinical diagnostic experts develop 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 experimented. In this way, we can speak of a language laboratory to name the teaching center where students learn and practice foreign languages.
Animal testing
The use of non-human animals to carry out laboratory experiments is known as vivisection , and this represents one of the most controversial faces of science. This is a practice that occurs not only in medical sciences, but also in the beauty, military, tobacco, and chemistry industries in general. Torture by human beings towards the rest of the species seems to know no limits.
The term guinea pig has its origins in the 16th century, a time in which man began to use other animals to explore the mysteries of our physiology , as well as to evaluate the effects of countless substances and medications, without forgetting the poisons, and various industrial procedures. Individuals of various species, from primates to dogs, have died and continue to be killed so that human beings can satisfy their thirst for superiority and their absurd need to prolong life.
Torture in laboratories
The main objective of laboratory experiments with animals is to perform toxicity tests, including dermal and oral toxicity tests, immersion, injection and inhalation studies and the Draize test. Pity, compassion and consideration are not 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 is an example of cowardice and absolute lack of sensitivity that takes place every day, in all parts of the world.
Thanks to undercover operations, various animal rights 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 to avoid becoming entangled in a public scandal.
No one will be able to give the millions of innocent victims their lives back; But science has shown that there are methods that do not use other living beings to test new substances, and therefore there is no excuse to continue with this massacre.
