Do I need to use pipettes with the cassettes?

No. Each cassette contains a built-in pipette. To load a cell sample into the cassette, submerge the pipette tip into the cell suspension and press on the piston. All cell sampling steps are performed within the containment of the cassette. Through this method, there are no user or pipetting errors to interfere with data generation, and the instrument’s software will tell you if you are working within the recommended cell concentration range.
