Double Pan Balance Parts And Functions

A triple beam balance is a device used to measure the mass of an object and all triple beam balances will have many of the same critical parts.

All quantitative analyses is the analytical balance used for the accurate weighing of samples and precipitates. As a general rule the balance should be completely arrested while making any changes that move any parts of the instrument. First the pan is where you place the sample whose. The triple beam balance is a measuring instrument comprising a beam supported on a fulcrum.

This scale can be used to determine the mass of an object. The measuring pan of an analytical balance 0 1 mg or better is inside a transparent enclosure with doors so that dust does not collect and so any air currents in the room do not affect the balance s operation. The parts of a double pan balance are the two weighing pans the pointer rider or sliding mass and rider arm. This enclosure is often called a draft shield.

On one side of this beam is a pan on which the object to be measured is placed while on the other side the beam is split into three parallel beams each carrying a known weight and together culminating into a pointer pointing to a fixed scale. The balance also balance scale beam balance and laboratory balance was the first mass measuring instrument invented.

An analytical balance or lab balance is a class of balance designed to measure small mass in the sub milligram range. Characters and elements are trademarks of the jim henson company. In microanalyses the balance must be about 1 000 times more. Triple beam balance definition.
