What is the different laboratory equipments

Laboratory equipment refers to the various tools and equipment that are used by professionals  in a laboratory. The different laboratory equipments used are safety glasses, balaces, scales, Graduated cylinder, Bunsen burner, microscopes, beakers, calorimeters and many more, these equipments are used to take measurements and to collect data.


Safety Glasses

Good laboratory safety practice is necessary for the efficient as well as productive functioning of any lab. Eye protection is required where there is the opportunity of chemical, environmental, radiological or mechanical irritants as well as hazards. Goggles, or protection glasses, are forms of protective eyewear that typically enclose or defend the area surrounding the eye in order to prevent particulates, water or chemicals from striking the eyes. Many types of goggles are accessible as prescription goggles for those with vision problems. Similar to normal glasses, however, it has a plastic shield on the side of the glasses.

Laboratory Balances and scales

Accurate Laboratory Analytical Balances as well as scales are a must for your laboratory operation. Laboratory balances are defined by high levels of accurateness and precision in analytical testing as well as quantitative analysis. Utilized in a variety of applications, they are divided into five subcategories according to their readability:
  • Analytical balances (0.0001 g)
  • Precision balances (>= 0.001 g)
  • Micro balances (0.000001 g)
  • Semi-micro balances (0.00001 g)
  • Ultra-micro balances (0.0000001 g)
Suitable for utilization in laboratories, manufacture according to pharma as well as quality control, as well as academic research and any other specialized use, Sartorius lab balances are equipped to meet the highest standards of speed, reliability as well as protection.

Graduated cylinder

This is major measuring equipment for the volume of a liquid. There are several markings up as well as down the length of the container with specific increments. Graduated cylinders come in several sizes.

While reading the volume from a graduated cylinder, you will notice that the liquid seems to have an indentation. The liquid around the edges will be higher than the liquid in the center, sloping down like the sides of a trampoline while somebody is standing in the middle. This is called the meniscus. Line the lowest point of the meniscus up with the adjacent marking, keeping the cylinder level to properly read the volume.

Burette

Buret, laboratory apparatus utilized in quantitative chemical analysis to calculate the volume of a liquid or a gas. It consists of a graduated glass tube within a stopcock (spigot or turning plug ) at one end. On a liquid burette, the stopcock is at the bottom as well as the accurate volume of the liquid dispensed can be determined by reading the graduations marked on the glass tube at the liquid level before as well as after providing it. In a gas burette, the stopcock is at the top; the tube of the burette is filled with a fluid, such as water, oil, or mercury as well as the bottom of the tube is full to a reservoir of the fluid. Gas is composed by displacing fluid from the burette, and the amount of gas is measured by the volume of fluid displaced.
