How can Cytocare be more precise than a human while dosing liquids with syringes?
Syringes themselves are rather inaccurate. The first problem is related to syringe markers, the second problem to the dead space at the end of the plunger’s route. The ISO standard 7881-1 on syringes allows low precision levels (4% is tolerated). When an operator is manually filling the syringe, he/she is likely to be very inaccurate, as he/she relies on markers printed on the syringe itself. Cytocare does not rely on markers, as it measures the exact plunger’s travel with two different and parallel systems. It uses an optic encoder on the motor moving the piston and a laser pointer. The precision level Cytocare can reach is thus by far higher than a human. We expect a no worse than 1% low precision on doses higher than 1ml.
