Accurate and precise pipetting performance is critical in laboratory analysis, particularly in highly sensitive tests where a small mistake in pipetting can cause a large error in the final result. Therefore it is of great importance to evaluate and to reduce, wherever possible, both random and systematic errors in liquid sample handling. This article provides some tips on how to reduce these errors.

There are many factors related not only to the pipettor, but also to tips, environment, and the laboratory worker which affect pipetting. Even experienced users may obtain incorrect measurements from time to time. Therefore it is important to evaluate and to reduce, wherever possible, both random and systematic errors in liquid sample handling.

Single and multi channel air displacement pipettors with adjustable volumes were developed by the end of the 1960s and first manufactured in the beginning of the 1970s. After three decades of development, mechanical pipettors exhibit excellent accuracy and precision. Yet, results with mechanical and even electronic pipettors are still user-dependent.

Accuracy and precision are invaluable in microliter pipetting. Use this article to help you understand what each term means, and how a quality pipettor, quality tips, regular maintenance and consistent handling play an integral role in your ability to achieve consistently accurate and precise results.

As the tip is an integral component of the pipetting system, its shape, material properties and fit have a considerable influence on pipetting accuracy. Variation in any of these will cause error to the volume pipetted. Learn about how to select the right tips for your pipettors.

One of the most widely used tools in laboratories today is the mechanical air-displacement pipettor. These mechanical action pipettors sometimes fail to deliver as accurately or precisely as they should. Often it is due to a mechanical failure in the pipettor itself (e.g. contamination, damaged sealing or out of calibration), but even more often the reason is simply human error.

This paper presents the findings of an investigation into the aseptic pipetting lifetime of air displacement pipettors during serial pipetting, paying particular attention to carryover in pipettors used without filter tips versus those with filter tips.
