Each balance is supplied with a 120-volt AC adapter. All balances except OB2143 will run on a 9-volt battery, sold separately. The OB2143 model includes a draft shield. Best of all is our price. Flinn digital balances are a terrific value and so economically priced that you’ll want to order several of them for your laboratory.

Balance Care and Use
Digital Balances are an essential component of any high school science lab. Flinn Scientific carries balances that vary in precision from 1 g to 0.0001 g.

Following are tips to properly use, store and maintain balances.

• Balances should always be placed on a level and sturdy surface.
• Recalibrate balances every time they are physically moved from one location to another. If balances always remain in the same location, calibrate them at least once a month.
• Allow 15 minutes to an hour of warm-up time before using balances.
• Ensure that balances are free from drafts, excessive shaking and electromagnetic interference.
• It is important to zero, or tare, balances each time an object is removed as long as the value is not required for subsequent measurements. This will help ensure that the zero point of the balance is in conjunction with regular calibrations.
• Static can interfere with accurate weighing. Make sure the balance surface, objects and work area are free from static.
• To maximize balance life, keep the housing and platform clean. A damp cloth and mild detergent may be used to remove debris from under the platform.
• Store the balance in a cool and dry location.
• Unplug AC adapters and/or remove batteries when balances will not be used for extended periods of time.

Mastering Precision in the High School Science Lab: Mechanical vs. Electronic vs. Precision Balances.

In the world of high school science, equipping your laboratory with the right tools is paramount to successful experiments and accurate data collection. One indispensable tool is the electronic balance. As we delve into the world of electronic balances, exploring their uses, key features, calibration, safety guidelines, and best practices, you’ll gain a thorough understanding of how a quality electronic balance can elevate your high school science experience.

Understanding Electronic Balances

Electronic balances, also known as digital balances or precision balances, are essential devices for measuring the mass of substances with utmost accuracy. Unlike traditional manual beam balances, electronic balances employ advanced sensor technology and digital displays to provide precise and quick measurements. These devices are a cornerstone of scientific experimentation and are utilized across various disciplines, from chemistry and biology to earth science and physics.

What is an Electronic Balance Used for in a Science Lab? 

The applications of electronic balances in the high school science lab are diverse and indispensable:

Chemistry: Electronic balances are used for accurately measuring the mass of reagents, chemicals, and compounds. This precision is critical for stoichiometry, titration, and determining reaction yields.

Biology: In biology experiments, electronic balances play a crucial role in weighing samples, such as dissected organisms, to record their mass accurately. This data is fundamental for biological investigations.

Physics: In physics experiments, the accurate measurement of mass is essential for studying the forces and properties of objects. Electronic balances ensure precise data collection.

Environmental Science: For environmental science studies, electronic balances are used to measure the mass of samples such as soil, water, and air pollutants. These measurements are vital for understanding environmental impacts.

Best Practices 

To maximize the utility and longevity of your electronic balance, consider these best practices:  

Zeroing: Always zero the balance before use, and ensure it returns to zero after removing any containers or substances from the pan.  

Gentle Handling: Handle the balance and its components (such as the pan and draft shield) with care to prevent damage.  

Avoid Drafts: Electronic balances are sensitive to air currents. Use a draft shield to protect against drafts, which can affect measurements. 

Record Data: Keep a meticulous record of measurements, including the substance being weighed, its mass, and any additional relevant information. 

Regular Maintenance: Clean the balance as needed, and follow manufacturer guidelines for maintenance and service. 

Electronic balances are indispensable tools in the high school science lab, enabling precise measurements critical for various experiments across scientific disciplines. By understanding their applications, key features, calibration, safety guidelines, and best practices, you can harness the power of electronic balances to enhance the quality and accuracy of your experiments.  And if you are looking for electronic precision balances or other instruments or equipment for your lab, make sure to check out Flinnsci.com.
