BREATHALYSERS MOUTHPIECES

According to LabStand company policy and many requests of our customers,
we have introduced breathalysers mouthpieces with hygienic certificate to our offer.

ETHYL ALCOHOL
Ethyl alcohol (ethanol) is one of the best known chemical substances and probably the best known organic substance. Ethyl alcohol is expressed with formula C2H5OH (in short EtOH, Et=ethyl) or CH3CH2OH. Ethanol particles spatial structure is presented in the drawing.

Ethanol is a transparent liquid, mixing in any ratio with water and almost all organic solvents. Ethanol is slightly lighter than water, boils in 78.3ºC and freezes in very low temperature –114ºC. Other physical properties are presented in the table. Water values are presented for comparison purposes.
COMPARISON OF ETHANOL AND WATER PROPERTIES

Ethyl alcohol is a liquid with characteristic, sharp scent and acrid flavour. It is interesting, that from the objective point of view (in solution!) it is one of the most tasty simple organic substances (aside from carbohydrates, lipids and proteins). For sure it is the most tasty organic solvents, as nobody would drink e.g. acetone (nail remover), benzene (paint and glues solvent) or carbon tetrachloride (fire extinguishers filling fluid).

Alcohol is very well known as a stimulant in form of various alcohol beverages, containing variable percent content of pure ethanol.
As a unit per milles are used (‰), being 1/1000 of a whole, just like % is a hundredth part. 1%=10‰. At 1‰ a specific “humour” appears, which increases at 2‰. Mental processes are simplified, drinking person often becomes more eloquent, courageous and more easily establishes contacts, which in turn encourages to more frequent drinking. At 3-4‰ speech becomes mumbling, reasoning limited, consciousness disturbed, and motions ataxia appears. In such state drinking person may easily commit crimes. Vomiting often appears, which prevents further alcohol concentration increasing.

Some people are however able to increase EtOH concentration to 5‰, which leads to narcotic dream with insensitiveness to various stimuli. When a person with alcohol concentration at approximately 3-4‰ quickly drinks large amount of alcohol and does not vomit, its concentration may exceed 6‰. 6‰ of alcohol in the blood is the average lethal dose, causing 50% of deaths. There are however death cases known at 4‰, as well as various nature phenomena, withstanding even 9‰ (some Belorussia resident). It is worth to add that 9‰ is a concentration in e.g. dark beer, and statistically one of 7000 inebriations leads to death.

The basic organ neutralizing EtOH influence results is liver. It burns 0.1-0.12 g of EtOH/h per 1 kg of body weight for men and approx. 0.08-0.09 for women, which more easily become drunk and longer recover. Alcohol oxidation is transformed into acetic aldehyde, acetic acid and finally into CO2+H2O. Quite large amount of energy is released, equal to heat of combustion of proper alcohol amount. In the fifties of 20th century there were “ideas” of adapting alcohol as the only energy source for people. But they have led to failure.

Alcohol processing liver becomes used with time, just like engine combusting fuel. With time liver and nervous system become damaged and destroyed (single inebriation destroys irreversibly approximately 6 millions of neurons from approximately 20 milliards that we have), as well as many important organs, which through various alcoholism stages leads to death.
