The normal ambient conditions for your laboratory

A laboratory must have a basic atmosphere for its proper functioning among them we have:


It is usually advisable to reduce the humidity as much as possible because it accelerates the oxidation of the instruments (commonly steel); however, to achieve laboratory habitability it cannot be less than 50% or more than 75%. If the latter value is exceeded, moisture may affect the laboratory.

Atmospheric pressure

The standardized atmospheric pressure is usually slightly higher in industrial laboratories than outside (25 Pa) to prevent dirty air from entering the production areas when the access doors are opened. In the case of biohazardous laboratories (manipulation of infectious agents) the situation is the opposite, since the escape of air from the laboratory that may be contaminated must be avoided, so the pressure will be slightly lower than the external pressure and the temperature must be 16 °C.

Mains power supply

All laboratories must have an emergency electrical system, different from the normal electrical network, where appliances such as freezers, refrigerators, incubators, etc. are plugged in to avoid problems in the event of blackouts. You can buy it in Kalstein


It is controlled, for example, in rat laboratories, as the presence of dust modifies the behavior of light as it passes through the air. In dimensional metrology laboratories, dust affects the measurement of dimensions on different parts.

Vibration and noise

Apart from the inconvenience of their presence for researchers and laboratory technicians, they can distort measurements made by mechanical procedures. This is the case, for example, with coordinate measuring machines.

How many of these conditions does your laboratory meet?
