An analytical balance is a laboratory instrument capable of providing fairly accurate measurements, as they are equipped with a system capable of measuring minimal differences in mass. They are usually designed with a transparent box with doors for the door, which isolates the balance from factors that may affect its operation and operation.
This equipment is commonly used to determine the mass of an object, it provides a high degree of precision in the order of 0.001 grams, in fact, modern analytical balances, can offer precision reading values from 0.1 µg to 0.1 mg, For its proper functioning, the analytical balance must be located under a specific environment and have controlled environmental conditions so that it does not suffer alteration in the absolute value of weighing.
Main technical characteristics of an analytical balance
An analytical balance is an instrument that has a special design, because it has a comfortable structure, a perfect size and a box made to protect the interior of the cabin in which the materials are placed despite. This design is intended to prevent external factors from interfering with the measurement of the sample. Likewise, it is important to keep in mind that the samples to be measured must be at a correct temperature because any change in this generates alterations in the results.
The analytical balance is specially designed to measure small masses, because it is able to measure up to 0.01 milligrams, reaching even 200 grams without problems. Even the most modern analytical scales manage to measure up to 0.001 milligrams, which is commonly observed in several laboratories. On the other hand, analytical balances have a number of other specific characteristics, such as the fact that they are always located on a surface that does not move, so that the balance does not slide or move in any way. This is because the sudden movement is able to modify the measurement result, altering it and generating erroneous results.
What is an analytical balance used for?
The analytical balance is routinely used in many laboratories, they are especially useful tools for weighing the necessary ingredients in the manufacture of solutions, compounds and medicines.
Among the main applications where analytical balances are used are:
- Preparation of standards.
- Determination of density.
- Interval weighing.
- Routine testing of micropipettes.
- Sample preparation.
How does an analytical balance work?
The operation of an analytical balance is based on the combination of various elements that work together and in parts, so that each of them generates a reaction that will eventually allow the accurate measurement of the samples. Analytical balances are composed of a saucer, an electromagnet and a photocell, a grouping known as the electromagnetic system.
The principle of operation is that the photocell seeks to detect the saucer and analyzes all the movements it performs depending on the size placed on it. Once this happens, the electromagnet generates the balance so that the force exerted by the mass in the saucer is analyzed. After these steps, the results are almost immediately visible on the screen in the front of the analytical balance structure.
Proper operation of an analytical balance
In order for an analytical balance to function correctly, it is advisable to comply with the basic equipment care, such as: always check the calibration of the balance, leave it plugged in and on to maintain the thermal balance of the electronic circuits, but always leave it in stand by mode, avoiding the need for a new heating time. And finally, constant care must be taken with the weighing bottle and plate, reading, calibration and balance maintenance to ensure accurate weighing.
It is recommended that the calibration of the analytical balances be performed periodically, especially when it is being used for the first time, if it has been moved, after any leveling and after large variations in temperature or atmospheric pressure, the modern analytical balances perform this function, automatically, when they detect any environmental variation.
