Overview
he PDES Pneumatic Drug Ejectrion System is a device for intracellular microinjection and extracellular dispense of liquids in the picoliter and nanoliter range.
This category of equipment is also known under the generic name “Picospritzer”
PDES modules for the EPMS system are available with digital manometer, digital timer and one channel. They can be operated using an internal or an external valve. Maximum pressure is 4 bar / 58 psi.
PDES systems are also available as 19″ stand-alone devices.
