Pipette Technology Over the Years
Did you know that mouth pipetting was once a common practice in labs? The method involved scientists using their mouth to create suction and transfer liquids, like sipping a straw. The technique posed serious risks, including exposure to harmful substances as well as contamination of samples. The practice began to decline in the 1970s with the introduction of piston-operated pipettes as a safer alternative.
Inspired by his frustration with mouth pipetting, Heinrich Schnitger's pioneering work at the University of Marburg in Germany, in the 1950s led to a patent in 1961 and development of the first micropipette, which revolutionized liquid handling in labs. Schnitger's invention laid the foundation for modern micropipettes, which have since become indispensable tools in scientific research.
The introduction of adjustable micropipettes by Warren Gilson and Henry Lardy in the 1970s gave scientists even greater control over liquid volumes and improved the accuracy of their experiments. In the years since then, micropipettes have evolved significantly, with modern models incorporating advanced technologies such as electronic control and improved calibration.
The continued development of micropipettes in the 21st century has seen remarkable strides, with highly advanced robotic models common in laboratories worldwide. BRAND has played a significant role in the evolution of liquid handling with innovative products like the Transferpette® S pipettes, the Handystep® touch repeating pipette with touch screen automation and the LHS – Liquid Handling Station Pipetting Robot to address the needs of modern laboratories. With ongoing advancements in design and technology, pipettes continue to shape the landscape of scientific research, enabling discoveries across a wide range of disciplines.
