Dual tip array dispensing head

This is an automated lab machine designed to handle liquids for experiments. It features a unique dispensing head that can pick up and use two different sizes of pipette tips, or tips at different spacings, all controlled by a single motor. The claims specifically describe this system as using a single drive to actuate a block connected to separate pistons for both large and small tip couplers.

Why it matters: Since 2015, advanced manufacturing techniques like 3D printing have made custom mechanical components, such as the specialized tip couplers and piston block, significantly more accessible and cost-effective to produce. Concurrently, the cost and power of microcontrollers for automation have improved.
