What are balance accessories used for in the lab?
Balance accessories help in the usage and maintenance of weighing equipment within the lab. Proper use and maintenance of weighing equipment is essential in having precise and reliable measurements.
What are common lab balance accessories?
There are various balance accessories that are common in the lab that are beneficial for use when high precision weighing and measuring is required, including:
- Anti-vibration tables - provides a level and sturdy surface and helps reduce the risk of external vibrations.
- Draft shields – provides protection from air currents, dust and vibrations.
- Weighing pans – highly sensitive for precision weighing and usually enclosed to shield from air currents.
- Calibration weights – help to check the accuracy of the weighing device being used.
- Density determination kits – used for determining density of solids and liquids.
- Sample holders – ensures stability of samples during measuring.
- Printers – helps reduce the risk of errors from hand-written records and provides efficiency.
- Software - for digitization of data management
Why are anti-vibration tables important for balances?
Anti-vibration tables help minimize vibrations and disturbances from the environment, ensuring stable and accurate readings, especially for high-precision analytical and microbalances that are sensitive to external vibrations.
What is the purpose of a draft shield in weighing applications?
A draft shield is essential during weighing and measuring as it protects the balance from air currents, dust, and other environmental factors that can affect the accuracy of measurements, particularly for small or lightweight samples.
Can I use any weighing pan with my balance?
It is recommended to use weighing pans that are specifically designed for your balance model. Using incorrect pans can lead to inaccurate measurements or even damage the balance.
What are calibration weights, and why are they needed?
Calibration weights are precision weights used to verify and adjust the accuracy of a balance. Regular calibration with these weights ensures that the balance continues to provide accurate measurements over time.
How do I choose the right accessories for my balance?
Choose accessories that match the specific requirements of your balance model and the type of measurements you perform. Refer to the balance manufacturer’s recommendations for compatible and beneficial accessories.
