Pressure Monitored Pipetting (PMP) is used for real-time quality control of the liquid transfer process. Integrating PMP into the Freedom EVO series of liquid handling workstations can improve process safety, especially for liquid transfers that are prone to blockage. Under the control of FreedomEVOware® software, PMP measures and records the pressure in the pipetting channel during aspiration and dispensing, and immediately compares the measured contour with the real-time simulated contour. Then, it explains the difference between the two configuration files and reports any problems that may lead to incorrect dispense volumes. Immediately detect and label common sources of pipetting errors in the laboratory, such as blocked tips or air suction. The system can prompt the user to solve the problem, or execute a predefined error recovery protocol. The software also includes predefined parameters for serum, aqueous solution and DMSO, and can be easily adjusted for other liquids.
