The dead volume of the injection system (injector needles, syringes, valves and
tubing) is approximately 100 µl after 'backflush' for each syringe. The function of
backflush is to return any unused reagent to the reservoir bottles. The injection
speed can be adjusted via the software to allow for good mixing of reagents. The
optimum injection speed depends on the assay parameters, such as viscosity of
fluids, the plate format and the measuring behavior of the liquids.

Before starting a measurement make sure that:
The tubes are clean. If not please refer to chapter 2.3.4 Priming and
Washing of the infinite
The injector tubes are correctly inserted into the storage bottles and fixed.
The injector system is primed. It is not possible to start a measurement
without priming the system.
When priming the system:
1. Check the tubes for leaks.
2. Check the tubes for kinks.
3. Make sure that the injector needles are not twisted.
If the tubes require replacement for any reason, after the tubes have been
changed do not forget to perform washing and priming before starting a
measurement.
