Lab balances are highly accurate weighing instruments that measure the mass of a sample with a very high degree of precision. They are available with capacities from 2.1 g up to 64 kg and readabilities ranging from 0.0001 mg (7 decimal places) to 1000 mg (0 decimal places). Lab balances are available in different types, including microbalances, analytical, precision, and automatic balances. METTLER TOLEDO lab balances are high-quality and offer top measurement performance, simple operation, exceptional ergonomics, and support with compliance.
A lab balance is a highly accurate and robust weighing instrument with a capacity ranging from 2.1 g to 64 kg, and readability from 0.0001 mg (7 digits) to 1000 mg (0 digits). Laboratory balances come with smart features to simplify work, optimize workflows, and support compliance with regulations.
We have a wide range of lab balances that suit every lab application and needs. See examples of lab balances below.

Laboratory balances are used to measure mass of materials with high accuracy. They have a wide range of uses in industries such as pharmaceutical, chemical, food, battery, and are used in research and development, manufacturing, and quality control. Some example applications are the following:
Formulation application on an MS-TS lab balance:
A laboratory balance should be used under optimal conditions in a stable weighing place. For a deep dive into how to use a laboratory balance correctly, check out the Proper Weighing Guide. Refer to the section "What are the most important factors to consider when using a laboratory balance?".
When using a lab balance, ensure the balance is properly level and adjusted.

Press zero to weigh on your laboratory balance. If available, open the draft shield and put the tare container on the weighing pan. Gloves or tweezers may be required. Press tare and dose the sample until the target weight is reached or place the object to be weighed on the weighing pan after zeroing. If available, the draft shield door is to be closed to release the mass value. After the weighing process is completed, ensure your lab balance is clean and ready for the next weighing.
