1. Beam balance / Triple-beam Balance
This traditional balance consists of three beams with sliding weights. To use it, you place the sample on the pan and adjust the weights on each beam until the pointer in the middle beam is at zero. The sum of the weights gives the mass of the sample.
2. Electronic balance
The electronic balance is a more modern version that uses electrical components to measure mass. It displays the mass digitally on a screen, making it easier to read and record measurements accurately. Electronic balances are typically more precise and faster than triple-beam balances.
Apparatus for Measuring Time
1. Stop watch/clock
A standard apparatus for measuring time using hours, minutes and seconds.
Apparatus for Scooping
1. Spatula
A spatula is a simple but versatile laboratory tool that is widely used for various purposes. A spatula is used to scoop solids which do not require accurate measurementa. Spatulas are used to accurately measure and transfer small quantities of solid substances, such as powders or crystals which do not require accurate measurement, to weighing scales or reaction vessels.
b. Spatulas are useful for gently mixing or agitating substances in test tubes or other small containers.
c. Spatulas help in scraping off residues or precipitates from containers and surfaces during experiments or clean-up.
2. Deflagrating spoon
A deflagrating spoon, also known as a combustion spoon or a deflagration spoon, is a specialized laboratory tool designed to hold small quantities of solid substances during combustion or deflagration experiments. It is commonly used in chemistry labs for qualitative analysis, particularly in tests involving flame reactions or ignition of substances.
