A

[pic 1]Analytical balance: It is a kind of laboratory scale designed for measuring small masses, initially to lower milligram range. The dishes measuring an analytical balance are inside a transparent box equipped with doors so that dust does not build up and prevent any airflow in the room affects the operation of the balance.

B

[pic 2]

Beaker: It is a cylindrical vessel of fine borosilicate glass is most commonly used in the laboratory, especially to prepare or heat transfer liquids and substances.

[pic 3]

Bunsen Burner: A Bunsen burner or burner is an instrument used in scientific laboratories to heat or sterilize samples or chemical reagents.

[pic 4]

Burette: It is a long glass tube in tenths of a cubic centimeter, which is open at one end and the other end in a cap with key; used in the laboratory to determine volumes.

C

[pic 5]

Centrifugal pumps: Centrifugal pumps are used to transport liquids at every stage of the process, and is one of the most sensitive components used in the petrochemical industry.

[pic 6]

Conveyor belts: The conveyor systems are often used to transport raw materials. This implies a high resistance requirements for bearings for factors such as temperatures and contamination. 

D

[pic 7]

Decanting funnel: It is used for separating immiscible liquids taking the difference between their densities, the denser is discharged from the bottom of the funnel.

E

[pic 8]

Electric motors: Electric drives for pumps, compressors, blowers and conveyor belt systems must withstand high operating temperatures and a high speed.

F

[pic 9]

Fans: Fans are required for a wide range of cooling processes. In most cases, these involve a high velocities and temperatures that can reach 200 ° C.

[pic 10]

Flask: Glass container, generally spherical in shape and with a straight and narrow neck, which is used in laboratories to contain and measure liquids.

G

[pic 11]

Graduated cylinder: A graduated cylinder is used in a variety of laboratory tests. The main function of a graduated cylinder is to measure fixed quantities of liquids, including potentially acidic liquids. The cylinder design allows them to make raw measurements and allows pouring liquids.

L

[pic 12]

LNG pumps: Pumps liquefied natural gas (LNG) are used to load / unload cryogenic liquids in tanks. The bearings used in this operation must be able to withstand a temperature of the liquid gas -162 ° C, and are partly lubricated by the pumping medium itself.

M

[pic 13]

Melting pot: Refractory vessel which serves to melt a metal at very high temperatures, used in the chemical and metallurgical industry.

P

[pic 14]

Pipette: It is a volumetric laboratory instrument that measures the rate of fluid quite accurately.
