Scientific research is heavily dependent on specialised equipment and when the supply chain is compromised the results can be alarming. In the wake of the COVID-19 pandemic the scientific research sector is experiencing major delays in acquiring disposable plastic pipette tips, small but important pieces of equipment used to transport small quantities of liquid. The tips attach to a more sophisticated micropipette apparatus, which can be set to aspirate a pre-set amount of liquid in the microlitre range.
COVID-19 testing fuels shortage
Widespread COVID-19 testing has fuelled the shortage, with the average test requiring four pipette tips. With the US carrying out roughly 1 million tests per day, demand for pipette tips is enormous. It’s not just epidemiologists who rely on pipette tips, with the plastic nibs also used in genetics research, diagnostic screenings, bioengineering and other applications. Even when scientists are not handling highly infe

Accuracy and precision are top priorities in laboratories. Not only do accurate and precise measurements ensure reliable results, but they also improve occupational health and safety in the workplace. Pipettes play an important role in maintaining accuracy and precision in laboratories, with the tools used to aspirate, measure, transport and dispense small volumes of liquid.
So how precise is a pipette? Continue reading as we explore the accuracy of pipettes, why it matters and how to keep your tools as precise as possible.
Micropipettes
Patented by German physician Heinrich Schnitger in the 1950s, micropipettes marked a new era of accuracy for scientists. After becoming increasingly frustrated with glass pipettes while teaching at the University of Marburg, Schnitger invented a version featuring a spring-loaded piston and a removable plastic tip. The design was quickly snapped up by German-based life science company Eppendorf, which began mass prod
