Laboratory equipment refers to the equipment which is used by scientists working in a laboratory. These include tools such as Bunsen burners, and microscopes as well as specialty equipment such as operant conditioning chambers, spectrophotometers and calorimeters etc. Another important type of laboratory equipment is Laboratory glassware such as the beaker or reagent bottle. These equipments is used for various purposes in laboratory either perform an experiment or to take measurements and gather data. And these are specially design for the purpose to perform various experiments in laboratory.
There are some example of laboratory equipment with their detail explanation about its uses and works.
A spectrophotometer is a photometer that can measure intensity as a function of the light source wavelength. Important features of spectrophotometers are spectral bandwidth and linear range of absorption or reflectance measurement. Spectrophotometer is commonly used for the measurement of transmittance or reflectance of solutions, transparent or opaque solids, such as polished glass, or gases. However they can also be designed to measure the diffusivity on any of the listed light ranges that usually cover around 200nm – 2500nm using different controls and calibrations. Within these ranges of light, calibrations are needed on the machine using standards that vary in type depending on the wavelength of the photometric determination.
A calorimeter (from Latin calor, meaning heat) is an object used for calorimetry, or the process of measuring the heat of chemical reactions or physical changes as well as heat capacity. Differential scanning calorimeters, isothermal micro calorimeters, titration calorimeters and accelerated rate calorimeters are among the most common types. A simple calorimeter just consists of a thermometer attached to a metal container full of water suspended above a combustion chamber. There are various types of calorimeter like adiabatic calorimeter, reaction calorimeter, heat flow calorimeter, heat balance calorimeter etc.
A beaker is a simple container for stirring, mixing and heating liquids commonly used in many laboratories first designed in 1453. Beakers are generally cylindrical in shape, with a flat bottom. Most also have a small spout to aid pouring as shown in the picture. Beakers are available in a wide range of sizes, from one millilitre up to several litres. Beakers are commonly made of glass but can also be in metal (such as stainless steel or aluminium) or certain plastics (notably polythene, polypropylene, PTFE). A common use for polypropylene beakers is gamma spectral analysis of liquid and solid samples. Beakers are often graduated, that is, marked on the side with lines indicating the volume contained. For instance, a 250 mL beaker might be marked with lines to indicate 50, 100, 150, 200, and 250 mL of volume. These marks are not intended for obtaining a precise measurement of volume (a graduated cylinder or a volumetric flask would be a more appropriate instrument for such a task), but rather an estimation.
Now there are also various types of laboratory equipments which are used in many purposes in laboratory and these are easily available in the market at very reasonable prices also.
