Electronic Balance Care
10 Tips to Maintain Electronic Balances
Electronic balances are used throughout higher education laboratories, from introductory science courses using budget-friendly balances to the more expensive analytical balances used in research laboratories. To ensure accuracy and promote an extended life for all balances, proper care and continued maintenance are crucial. Use the 10 tips below to maximize the longevity of your instrument.
- Balances should always be placed on a level and sturdy surface.
- Allow 15 minutes to an hour of warm-up time before using balances. Analytical balances will require more warm-up time than those with lower readabilities.
- Moisture in the air can condense on the surfaces of a cold balance whenever it is brought into a substantially warmer place. If you transfer the balance to a warmer area, make sure to condition it for about 2 hours at room temperature, leaving it unplugged from AC power.
- Ensure balances are free from drafts, excessive shaking, and electromagnetic interference. Consider using draft shields to control air flow and anti-vibration balance tables to control shaking.
- Static can interfere with accurate weighing. Make sure the balance surface, objects, and work area are free from static. Investigate grounding the work surface or the use of anti-static lab mats and apparel.
- Store the balance in a cool and dry location.
- Do not store balances in chemical storage areas where chemical (corrosive) fumes could damage the balances.
- Unplug AC adapters and/or remove batteries when balances will not be used for extended periods of time.
- Recalibrate balances every time they are physically moved from one location to another. If balances always remain in the same location, calibrate at least once a month.
- To maximize balance life, keep the housing and platform clean. Use a clean, damp cloth to remove debris from the balance body and pan, followed by a dry cloth. If the pan is removable, remove pan for cleaning. Unidentified debris should be cleaned up while wearing proper protective equipment (gloves, goggles, and apron).
Above all, always follow manufacturer recommendations and guidelines specific to your balance. If you have any questions, please contact us.
