Laboratory balances: kilos, grams, micrograms

Mass is one of the quantities that needs to be evaluated in the laboratory, either to prepare reagent solutions, specimens or samples for a given analysis, with the accuracy and precision required by the quality of the study to be carried out.

Mass is defined as the amount of matter that a body has. The Unit of the International System of Measurements (SI), fundamental to measure mass is the Kilogram (Kg), however in chemistry the gram (g) is used, since it is a smaller unit and at the same time more convenient in chemical studies .

Analytical balance

The analytical balance is one of the most widely used measuring instruments in the laboratory and on which basically all analytical results depend. Modern analytical balances, which can offer reading precision values โ€‹โ€‹from 0.1 ยตg to 0.1 mg, are well developed so that the use of special rooms for weight measurement is not necessary.

Electronic precision balance

A precision electronic balance is an instrument that is used to weigh through the intervention of gravity in order to determine a mass in question. Use a plate where the object to be measured is placed. Then the load cell is the one that allows to measure the weight exerted by the mass to be determined. Precision balances are used in laboratories and are practically essential for all tasks carried out there.

The resolution of these balances varies according to the model, the same happens with the working range. They generally have a resolution that can reach 0.01 g of resolution.

Granataria balance

The granataria scale is one of the most frequently used items to measure. The objective for which these types of scales are intended is to determine the general mass of a substance or to weigh a certain amount of that mass.
