Accurate volumetric measurements are crucial to research and diagnostics. Instruments like pipettes, burettes, and dispensers, also known as piston-operated volumetric apparatus (POVA), are essential in achieving this precision with their proper use and calibration significantly impacting the accuracy and reproducibility of experimental results. Thus, being updated on the vital practices for proper calibration and testing of your lab’s POVA helps ensure every measurement is precise.
ISO 8655:2022, the revised standard for POVA calibration and testing, introduces key enhancements. These include integrating pipettes and tips as unified systems, requiring manufacturers to demonstrate their combined accuracy under specified conditions. The standard also offers alternative calibration methods, such as photometric alongside traditional gravimetric techniques, providing more flexibility for laboratories. With stricter protocols for calibration, including using multiple tips and conducting thorough pre- and post-maintenance assessments, ISO 8655:2022 aims to significantly improve measurement reliability.
