Pipette Accuracy: Best Practices Between Calibrations for Labs

Introduction

Pipettes are the unsung heroes of the modern laboratory, quietly and precisely dispensing liquids that underpin countless experiments and analyses. However, their accuracy is paramount; even minor deviations can cascade into significant errors, compromising research integrity and potentially leading to flawed conclusions. While regular calibration is essential, maintaining pipette accuracy between these scheduled checks is equally crucial. This article delves into practical strategies and best practices that Soft Tech Serv, an ISO 17025 accredited calibration laboratory, recommends for ensuring your pipettes consistently deliver reliable results.

Maintaining pipette accuracy isn't merely about adhering to regulatory requirements or avoiding costly mistakes. It's about fostering a culture of precision and reliability within the lab. By implementing these best practices, laboratories can minimize variability, enhance reproducibility, and ultimately, strengthen the validity of their scientific findings. This guide provides actionable steps for proper handling, storage, and routine checks, empowering lab personnel to proactively safeguard the performance of their pipettes.

Understanding the Importance of Inter-Calibration Maintenance

Calibration provides a snapshot of a pipette's performance at a specific point in time. However, various factors can influence accuracy between calibrations, including frequency of use, the types of liquids dispensed, environmental conditions, and even the user's technique. Neglecting these factors can lead to gradual or sudden deviations from the calibrated state, impacting the reliability of experimental data. Regular inter-calibration maintenance acts as a preventative measure, mitigating these risks and ensuring consistent performance.
