An analytical balance (or chemical balance) is a class of balance designed to measure small mass in the sub-milligram range. The measuring pan of an analytical balance (0.1 mg resolution 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 triple beam balance are identified as the following. [3]Weighing pan - The area in which an object is placed in order to be weighed.; Base - The base rests underneath the weighing pan and can usually be customized to fit on a workbench or set up with tripod legs.
A microbalance is an instrument capable of making precise measurements of weight of objects of relatively small mass: of the order of a million parts of a gram.In comparison, a standard analytical balance is 100 times less sensitive; i.e. it is limited in precision to 0.1 milligrams.
The balance (also balance scale, beam balance and laboratory balance) was the first mass measuring instrument invented. [1] In its traditional form, it consists of a pivoted horizontal lever with arms of equal length – the beam or tron – and a weighing pan [10] suspended from each arm (hence the plural name "scales " for a weighing instrument).

In physics, a mass balance, also called a material balance, is an application of conservation of mass [1] to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique.
historically, used in human or animal experiments to measure and record data Long extension kymograph: historically, used in or human animal experiments to measure and record data Surface plasmon resonance: Label-free detection of molecule binding. Used to determine kinetic constants of the interaction (k a, k d, K D). Can also be used for ...
The load in a laboratory centrifuge must be carefully balanced. This is achieved by using a combination of samples and balance tubes which all have the same weight or by using various balancing patterns without balance tubes. [2] It is an interesting mathematical problem to solve the balance pattern given n slots and k tubes with the same weight.
