PDES Pressure ejection
The PDES enables substances to be applied from micropipettes with high-pressure outputs for fine pipettes or low-pressure outputs for wide pipettes. The system is available in single- or dual-channel versions, with analogue or digital timers and internal or external valves for application times of less than 1 ms. Each channel includes a precision pressure regulator, display, electronically controlled valves, control electronics and a regulated power supply. Injection can be triggered manually or via a TTL input and operating status is indicated by a red/green LED. Digital versions also allow pressure monitoring via BNC connector. The PDES is compatible with the EPMS-07 system and can be used with a pressure maintenance system (DHX).
