What are the uses of common laboratory apparatus?
What are the uses of common laboratory apparatus?
COMMON LABORATORY APPARATUS. Beakers are useful as a reaction container or to hold liquid or solid samples.
What is the most common lab equipment?
Laboratory machines and instruments ‒ stirrers, hot plates, precision balances, test kits, pH meters, water bath, incubator, microscopes, etc.
What are the uses of Beaker?
Beakers are useful as a reaction container or to hold liquid or solid samples. They are also used to catch liquids from titrations and filtrates from filtering operations. Laboratory Burners are sources of heat.
What common laboratory apparatus are used for volumetric measurements?
Volumetric flasks, burettes, and pipettes made for measuring small amounts of liquid are the most accurate, with tolerances of less than ±0.02.
What are the uses of burette?
A burette is used to dispense small volumes of liquid called aliquots, or sometimes gas, with high accuracy. It consists of a long glass tube with a valve at one end to control the flow of liquid. Burettes serve essentially the same purpose as a pipette.
What are the uses of glassware?
Examples of glassware used for measurements include:
- Graduated cylinders are thin and tall cylindrical containers used for volumetric measurements.
- Volumetric flasks are for measuring a specific volume of fluid.
What is the use of graduated cylinder?
Graduated cylinders are long, slender vessels used for measuring the volumes of liquids. They are not intended for mixing, stirring, heating, or weighing. Graduated cylinders commonly range in size from 5 mL to 500 mL. Some can even hold volumes of more than a liter.
What is the use of pipette and burette?
They both have gradations to measure the quantity of chemical substances. While burette is used to deliver a chemical solution with a known concentration into a flask, pipette is used to measure the quantity of the analyte- the chemical substrate whose concentration is to be determined.
What is the uses of volumetric flask?
A volumetric flask is lab glass or plasticware used to prepare a solution. It is used to make up a solution to a known volume. Volumetric flasks are used to measure volumes much more precisely than beakers or Erlenmeyer flasks.
What is the function of the burette?
burette, also spelled buret, laboratory apparatus used in quantitative chemical analysis to measure the volume of a liquid or a gas. It consists of a graduated glass tube with a stopcock (turning plug, or spigot) at one end.
What are the uses of a beaker?
Beakers are useful as a reaction container or to hold liquid or solid samples. They are also used to catch liquids from titrations and filtrates from filtering operations.
What is the use of graduated cylinder in laboratory apparatus?
What is the use of pipette?
To transport a measured volume of liquidPipette / Uses
What is use of test tube?
Test tubes are widely used by chemists to handle chemicals, especially for qualitative experiments and assays. Their spherical bottom and vertical sides reduce mass loss when pouring, make them easier to wash out, and allow convenient monitoring of the contents.
What are the common laboratory apparatus and their uses?
What are the 20 common laboratory apparatus and their uses? 1 1. Microscope. A microscope is a popular piece of lab equipment used to observe things that are too small and are not visible to the naked human eye. 2 2.Test tube. 3 3. Watch glass. 4 4. Crucible. 5 5. Volumetric flasks.
What are some examples of organic chemistry laboratory apparatus?
Büchner and Hirsch’s funnels are good examples of organic chemistry laboratory apparatus. 17. Wash bottle Wash bottle filled with a range of common laboratory solvents and reagents. Photo: Arpon Pongkasetkam A wash bottle is a squeeze container with an extended nozzle. It is used to rinse glassware and for sterilization.
What is an example of a laboratory instrument?
Examples of such instruments are Atomic Absorption Spectroscopy (AAS), High-Performance Liquid Chromatography (HPLC), balances, calorimeter, colourimeter, conductivity meters, and many more. Laboratory glassware: These are laboratory materials for measuring, pipetting, transferring, preparation of reagents, and storage.
What are the different types of lab equipment?
General lab equipment: They include, Baths/circulators, block digesters, centrifuge, cryogenics, desiccators, Environmental Growth Chambers, flowmeters, freezers, fume hoods, and furnaces. High-Performance Liquid Chromatography (HPLC): The instrument detects very small amounts of solvents and separates a wide variety of chemical mixtures.
