Practical Selection Guide How to Select a Mechanical Pipette Points to consider when choosing a Mechanical Pipette Joni Åke Sartorius Biohit Liquid Handling Oy, Laippatie 1, 00880 Helsinki Finland Contact E-Mail: lhinfo.finland@sartorius.com Introduction Widely used in laboratories of all kinds, mechanical pipettes are long-lasting tools. Because they are used for several hours a day, ergonomics and personal preferences – such as handling comfort – are important selection criteria. Other factors such as the application, laboratory workflow, required volume ranges, physical properties of the sample, and requirements for accuracy and precision also need to be considered when searching for the right pipette for the job.

Accuracy and Precision Accuracy and precision are two of the most critical aspects when choosing a pipette. Accuracy means that the delivered volume equals the set volume. Precision expresses the proximity of multiple pipetting results. Here are some examples: The terms accuracy and precision are expressed in the technical specifications of the pipette as systematic error % (inaccuracy %) and random error % (imprecision %). It is worth noting that the specifications are typically valid only when using the manufacturer’s own pipette tips. The best accuracy can be obtained by using a high...

Ergonomics Pipetting is one of the most common tasks performed in a laboratory on a daily basis. Studies have associated pipetting with increased risk of upper body musculoskeletal disorder, and even more than 40% of lab professionals can suffer pipetting related disorders.* In addition to causing discomfort, hand or arm injuries limit working performance and may therefore impact accuracy, precision, and the reliability of results. For the best possible ergonomics, it is important to pay attention to the following qualities when choosing a pipette: Required pipetting force: High pipetting...

Air or Positive Displacement Pipette? There are two types of mechanical, piston-operated pipettes: air displacement and positive displacement pipettes. Air displacement pipettes, which are intended for general laboratory work and aqueous samples, have an air column between the piston and the liquid. Most pipetting work in laboratories is performed using this type of pipette. All pipettes need regular maintenance to ensure reliable results and maximum instrument lifetime. When choosing a pipette, it is important to consider the service aspects. Do you want the user to be able to perform...
