How to use the correct analytical balance? An analytical balance is a laboratory instrument used to measure objects with small mass (sub-milligram range). To get accurate measurement results from an analytical balance, you must know how to use them. Check out the following explanation to find out how to use analytical balance appropriately.
How to Use the Analytical Balance
Based on the type, analytical balance is divided into two types, namely digital analytical balance and analog analytic balance (manual). This article will discuss how to use analytical balances from the preparation stage to reading measurement results.
1. Preparation Stage
Before using an analytical balance to calculate the mass of an object, don't forget to prepare the instrument so that the measurement results you get are accurate. Here are the preparatory steps you must take.
Check Instrument Balance
The first step to take is to check the equilibrium of the instrument. You can find out the equilibrium of the instrument by examining the air bubbles at the back of the balance. If the bubble is centered, the instrument is balanced. However, if the bubble is not in the center, the instrument is still out of balance. To balance, you have to perform analytical balance calibration. Turn the screw at the bottom of the balance until the bubble is in the center.
Turn on the Balance
After confirming the balance of the instrument, you can turn on the balance. Make sure the entire glass cover is closed completely. If so, connect the instrument to the power supply and press the 'ON' button. Slowly the analytical balance will activate and then the monitor will show zero. Balance sheet ready to use.

2. Stage of Use
After the balance is active, you can immediately start weighing the ingredients, whether they are liquid or solid. Check out the steps in the points below.
1. Prepare a container to hold the ingredients. Make sure the container you use matches the properties of the ingredients. For example, for liquid materials you can use a measuring cup. As for solid materials, you can use the plate on the balance.
2. After the ingredients are ready, place them on the balance plate and close the scales.
3. Reset the balance to return to zero by pressing the 'Tare' button. This step will result in a direct measurement of the mass of the sample.
4. Place the container on the plate (pan) and close the lid of the scale.
5. Press the 'Tare' button. The monitor will display zeros because the housing weight has been reset. This way, you will know the sample weight / weight in real time.
6. Wait a few moments for the instrument to finish taking measurements.
7. Record the measurement results.
Keep in mind, always place material samples on the balance with care. Do not allow material to be scattered or spilled before measuring, especially if the sample used is a corrosive chemical such as a strong acid. It's a good idea to get the plate out of the balance when you put the material sample down.
3. Final Stage
When you are done using the analytical balance, make sure that no residual samples are left. If there is any dirt or sample residue left, wipe it off with a clean microfiber cloth. Remnants of samples that are not cleaned will quickly break the balance, especially if the sample is a corrosive material.
If the balance is clean and you don't use it anymore, turn off the instrument immediately. Press the 'OFF' button on the front of the balance. Next, unplug the balance power cord from the socket to cut off the flow of electricity. Always unplug the power cord when you are done using the analytical balance to avoid damaging the instrument due to changes in mains voltage,

Why You Should Use Analytical Balance Sheet
Analytical balance has a high level of sensitivity to the mass of objects, especially those in the sub-milligram range. Therefore, this one instrument is very suitable for objects with the following characteristics:
Sensitive
Sensitive here means that objects easily react to changes in the environment around them. For example, volatile objects such as alcohol. With an analytical balance, you can ensure the correct amount of alcohol without worrying about yawning.
Has a strong influence
Apart from being suitable for sensitive objects, analytical balances are also suitable for measuring objects that have a strong influence. Examples of objects that have a strong influence are chemicals such as concentrated sodium hydroxide.
That's a guide on how to properly use analytical balances. If you currently need an accurate analytical balance, Hyprowira sells the ME-T Analytical Balance from Mettler Toledo. ME-T is an analytical balance for all labs with intuitive operation. Hopefully this information on how to use analytical balances can help you!
