This document describes the accuracy and precision of the Velocity11 Bravo™ Liquid Handling Platform's 96-Channel 200 µL, which increases sample processing and throughput and improves accuracy and precision when compared to a person operating a handheld liquid pipettor.
The document presents a technical evaluation of the Velocity11 Bravo™ liquid handling platform, specifically focusing on its performance with a 96 Channel LT Disposable Tip Head. The study measures accuracy and precision across volumes from 1 to 5 µL using tartrazine/DMSO solutions and UV/Vis spectrophotometry.
Results indicate that at 1.0 µL the system achieves a coefficient of variation (CV) of 3.8% with +2.8% accuracy, while at 2.0 µL it reaches 2.8% CV and 1.1% accuracy. At 5.0 µL, performance improves to 1.3% CV and 0.7% accuracy. The document concludes that the platform provides precise, accurate, and consistent liquid transfers suitable for various laboratory applications.
At 1.0 µL, the system achieves 3.8% CV for precision and +2.8% accuracy.
Aspirate parameters are set to 5 mm from the bottom of the plate with a 2 µL pre-aspirate volume.
