Accurate and Consistent Serial Dilutions Made Easy


Changing the concentration of samples, reagents, and buffers is a daily reality in science. Accurate pipetting and thorough mixing during the serial dilution process is clearly critical, since any deviation will propagate to all subsequent steps.

Meet Andrew, the pipetting robot. Andrew performs serial dilutions with a level of accuracy that goes beyond what can be achieved by hand, eliminating biases such as variations in the pipette volume setting hysteresis, the pipette verticality, the tip insertion depth, the thumb speed, the tip insertion force, and the first-stop detection force.

Andrew is guided by Andrew Lab software, which makes designing a proper and perfectly reproducible experimental workflow easy by automatically calculating the required volumes and concentrations.
