Designed by Forman et al. (2017) for ease of use, robustness and low-cost, the “Openspritzer” is an open hardware “Picospritzer” as routinely used in biological labs around the world for rapid and reproducible ejections of picoliter and nanoliter volumes. The performance of Openspritzer and commercial alternatives was found to be effectively indistinguishable by the developers. The system is based on a solenoid valve connected to a pressure gauge; control can be obtained directly via an external TTL pulse or internally through an Arduino set by a rotary encoder.
