Typically, analytical balances like the ML303E/03 should be calibrated at least once per year by a qualified technician. However, many labs perform in-house verification/calibration more frequently (weekly, monthly, or even daily) depending on usage, regulations, and required accuracy. Manufacturer and ISO/GLP guidelines may require more regular checks.
