Automatic pipetting – both efficient and ergonomic!

29 November 2018

The exact and efficient transfer of samples in extremely small dosing volumes is essential in the life sciences industry. For this purpose, INTEGRA Biosciences AG developed a compact pipetting robot called ASSIST PLUS that draws and pipettes samples into the target container.

Part of this process is the automatic loading and ejecting of pipette tips, monitored by a customer-specific solution developed by Leuze electronic specially for INTEGRA Biosciences based on the polarised PRK 3B retro-reflective photoelectric sensor.

Electronic pipetting – a must in every lab!

Modern laboratories, whether in the biotech or pharmaceutical industry or in the academic realm, process and analyse an increasing quantity of samples. Yet the sample volumes and the corresponding labware are becoming smaller. The high sample quantity and strict requirements on accuracy and precision make manual pipetting a great challenge for the users. Furthermore, long, manual pipetting protocols can impact the health of the users, as classical, manual pipetting involves collecting and dispensing liquid using thumb movements. This can lead to the development of repetitive strain injuries. With modern pipettes, special focus is therefore placed on ergonomics by reducing the weight of the devices and by performing the pipetting operation electronically. An advantage of ASSIST PLUS is that the users themselves no longer need to pipette. The pipette can be clicked into the ASSIST PLUS holder, and the protocol is performed automatically. To prevent cross contamination of samples during critical applications, pipette tips are used only once. ASSIST PLUS does this by automatically loading new tips and then ejecting them into the provided tip waste container after the pipetting operation.
