What are Analytical Balances and how it is different from other Balances?

The word “analytical” in Analytical Balance means that they can be used to perform a quantitative analysis of a sample. Analytical balances are among the most precise type of balance. They are used for measuring tiny samples at the microgram level. They are primarily used in laboratories and research facilities wherein getting accurate weighed results are critical.

What is an Analytical Balance?

An analytical balance is designed to be used for measuring the mass of a sample. The sample is placed on a platform and get weighed using a lever system. It is a highly sensitive lab instrument to accurately measure mass. Its readability has range between 0.1mg – 0.01mg. These balances come with a weighing chamber for preventing very small samples from being affected by air currents.

 

How Analytical balances different From Other Balances

There are differences between Analytical balances and other types of balances in many ways.

• Analytical balances offer a much higher level of accuracy and precision.
• You can use them to measure very small amounts of material, such as in micrograms.
• These balances generally come with a built-in draft shield in order to protect the samples from drafts or other sources of error.
• Further, analytical balances offer automatic calibration features. It makes sure that the measurements are always correct.

 

Different types of Analytical Balances

There are different types of analytical balances are available in the market. They are designed based on the type of measurements they need to perform.

Top-loading balance

The most common type is the top-loading balance. It is used to measure the mass of objects and has a platform on which the object to be weighed is placed. The object is then weighed by suspending it from a beam that is connected to a set of scales.

Bottom-loading balances

These balances can be used for measuring the mass of liquids. Just place the object in a pan that is attached to the bottom of the balance. The liquid is then added until it reaches the desired level.

Floor-standing balances

Bring these balances to measure larger objects. A platform that is attached to the floor.  Place the object on the platform to let the balance measure its weight.

Conclusion

Analytical balances are the most specific type of balance that is essential for many types of scientific work. They are very different from other types of balances in terms of how they work and what they can measure. So it is necessary to understand the difference before choosing a balance for your needs.
