There are 2 different types of stopwatches, digital stopwatches (top left) and analog stopwatches (top right). They are accurate to 0.01s, and are used to measure speed.
Thermometer
Laboratory Thermometers are usually mercury thermometers, capable of measuring temperatures to the accuracy of 0.1°C. Commonly used to measure boiling points of aqueous substances.
Electronic balance
The electronic scale is a device for the measurement of mass. It is accurate to 0.01 grams, and is used to obtain a specific mass of a reactant.
Burettes
burette is a vertical cylindrical laboratory glassware with a volumetric graduation on its full length and a precision tap at the bottom. It is used to dispense known amounts of a liquid reagent in experiments for which such precision is necessary, such as a titration experiment. Burettes are accurate to 0.1cm3.
Pipette
Pipettes allow the user to measure a volume of solution extremely accurately and then add it to something else. They are commonly used to make laboratory solutions from a base stock as well as prepare solutions for titration. They are typically marked to indicate one single volume in a particular size
Measuring Cylinder
The measuring cylinder is a piece of laboratory equipment used to measure liquids to the accuracy of 0.1cm3
Gas Syringe
A gas syringe is a piece of laboratory glassware used to insert or withdraw a volume of a gas from a closed system, or to measure the volume of gas evolved from a chemical reaction. A gas syringe can also be used to measure and dispense liquids, especially where these liquids need to be kept free from air.
Hi,
ReplyDeleteThermometer, gas syringe, measuring cylinder, pipette and electronic balance are used in the chemical laboratory for measurements of solid and liquid chemical products. The professionals always try to take the accurate amount of chemicals for getting good and perfect results. Thanks a lot.
