*Pipetting specifications were determined gravimetrically using a high-precision balance and strictly controlled environmental conditions: test temperature: 20 ± 2°C, relative humidity: 50% ± 5%, test liquid temperature range: ≤± 0.5°C of room temperature, balance used: Mettler Toledo MX5. The measurements were done in Hamilton Verification Solution (deionized water with 0.1% NaCl and 0.01% Tween detergent) using standard CO-RE conductive tips. A new tip was used for each pipetting cycle (aspiration and dispense). At least 10 points were taken for each volume and pipetting module. Volumes > 20 μL were dispensed in jet mode. Volumes ≤ 20 μL were dispensed in surface mode. Results may vary using other liquid or environmental conditions.
