Abstract
A substance dispense system is provided for a biological sample analysis instrument. The substance dispense system can operate to prepare a fluidic substance, such as a sample, using a dispense tip in different operational modes based on the volume of the fluid substance to be prepared. The substance dispense system thereby improves accuracy and/or precision in pipetting with the dispense tip.
