Analytical Balance

Place the mouse over the image to zoom in

Description: An analytical balance (often called a "lab 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 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. This enclosure is often called a draft shield. The use of a mechanically vented balance safety enclosure, which has uniquely designed acrylic airfoils, allows a smooth turbulence-free airflow that prevents balance fluctuation and the measure of mass down to 1 μg without fluctuations or loss of product.

What is the use of analytical balance?

An analytical 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 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.

Our range in laboratory analytical balances includes a variety of features to suit your application needs. Models are available with internal or external calibration, built in RS-232 to allow connectivity to computers or printers and stability filters to compensate from vibrations, drafts or temperature changes. To ensure high accuracy weighing our analytical balances are available with a see-through enclosure to prevent dust, air or any other external factors to affect the reading of the balances.

Preparing the balance for use:

Before weighing anything on the analytical balance you must make sure that it is leveled and zeroed.
To check the leveling on the balance, look at the leveling bubble on the floor of the weighing chamber. If it is not centered, center it by turning the leveling screws on the bottom toward the back of the balance.
Once the balance is leveled, close all the chamber doors and press the control bar on the front of the balance. After a few seconds, a row of zeros will appear. This indicates that the balance is zeroed and ready for use.

These substances must always be weighed using an appropriate weighing container.

1. Place the weighing container on the balance pan and close the doors.
2. Tare the container by briefly pressing the control bar. The readout will read zero with the container sitting on the pan. This allows the mass of your sample to be read directly.
3. Add the substance to be weighed. Be careful not to spill chemicals on the balance. If need be, you can remove the container from the weighing chamber while you add the sample provided that noone presses the control bar before you weigh your sample.
4. With the sample and its container sitting on the pan, close the chamber doors and read the display to find the mass of your sample.
