Routine Testing of Lab Balances – How to Do It Correctly

Ensuring that balances used in the laboratory weigh accurately is at the heart of good science and safe manufacturing. It’s essential that any balance or scale is calibrated on a regular basis by a service technician. However, the user should still perform regular routine tests to uncover malfunctions early and avoid surprises at the next calibration service.

In many cases, defining test frequencies, adequate procedures and proper staff training can be a challenging and time consuming task.

This guide explains the four pillars of balance routine testing:

  • Testing frequency
  • Test methods and SOPs
  • Test weights
  • User training

Put routine balance testing into practice! It pays off to build quality into laboratory results from the start, rather than discovering problems later on.

Why is routine testing of laboratory balances so important?

Balances play a critical role in research, development, quality assurance and production. However, errors in weight measurements cost time and money, and violations of legal requirements may even cause damage to health and/or the environment. Maintaining and ensuring the performance of a device and reducing the risk of its being outside process tolerances requires the correct setup of the instrument and regular calibration by the service provider. Between service intervals, the user should perform regular routine tests to uncover malfunctions early and eliminate surprises at the next calibration service.

In many cases, defining routine test frequencies, adequate procedures and proper staff training can be a challenging and time consuming task, tying up valuable resources.
