Automation increases productivity and efficiency

Manufacturers and research institutes can expect to gain a wide range of benefits by using automation solutions in liquid handling. A dispensing system can precisely fill the wells of large microwell plates in the shortest possible time. Specialists are relieved of repetitive tasks and then have time for value-adding work, such as analysing results or developing new test procedures. In contrast to manual pipetting workflows, the processes are completely standardised. The potential for errors is reduced as each step is carried out using a standardised approach. The closed system creates a clean environment, minimising external disturbances to the cell cultures.

Festo LifeTech offers a wide range of components for a modular and flexible dispensing system based on compressed air. This allows liquids and, in particular, cell suspensions to be precisely dispensed in a gentle process. As cells are living organisms that are very strongly influenced by external conditions, the pressure used can be specifically adapted to the cell line and cell concentration.

Practical tests for the viability of cells

In collaboration with Esslingen University of Applied Sciences, Festo has tested the influence of dispensing with the pressure-controlled dispensing system from Festo on cell viability in comparison to pipetting using a manual pipette. Testing with a selected cell line has shown that the average viability of the cells was similar to that of the manually pipetted samples. That means the Festo dispensing system offers a very good basis for gentle and precise handling of cell cultures – with all the advantages of automation. Thanks to the modular design and the ability to adjust the parameters, the system can be adapted to different cell lines and cell concentrations.
