Pipetting system with displacement device for fluid management
The granted patent US12070743B2 describes a novel pipetting system that integrates a pipetting device with a displacement device. The pipetting device can be an air, fluid, or VCP pipetting device, while the displacement device consists of two fluid spaces. Each fluid space is divided into two chambers by a piston that provides fluid-sealing separation. The first fluid space is connected to the pipetting device, and the first piston is actuated by an actuation volume of working fluid from the pipetting device. The second fluid space operates simultaneously, with its piston displacing a different volume of fluid based on the actuation of the first piston. The system allows for the actuation volume to differ from the displacement volume, enabling precise control over fluid transfer.
Additionally, the patent outlines methods for translating fluid volumes and displacing fluid volumes using the described pipetting system. The actuation of the pistons can be achieved through various means, including mechanical, magnetic, pneumatic, or hydraulic forces. The design allows for the first piston to control the movement of the second piston, ensuring that the two pistons operate in a coordinated manner. The patent also includes provisions for connecting the fluid spaces and the pipetting device, as well as features such as pressure equilibrium means and measuring capacitors for enhanced functionality. Overall, this pipetting system aims to improve the efficiency and accuracy of fluid handling in laboratory settings.
