Benefits of the PDES
- Utilize ionic and non-ionic substances in minimal quantities
- Precise local application with the microJECT – a pipette holder featuring an integrated valve
- Also offered as a 19" stand-alone unit
Pneumatic Drug Ejection Module
The PDES Pneumatic Drug Ejection System serves as a device for intracellular microinjection and extracellular dispensing of liquids within the picoliter and nanoliter range. This type of equipment is commonly referred to as a "Picospritzer".
PDES modules designed for the EPMS system come equipped with a digital manometer, digital timer, and a single channel. They can function with either an internal or external valve. The maximum pressure capacity is 4 bar / 58 psi.
Specifications of the PDES
Source gas: air, nitrogen, helium etc. no aggressive, combustible or explosive gases, filtered by a 5 µm filter element
Pressure range:
- input pressure:
- max. 5 bar (1 bar = 105 Pa)
- pressure control range:
- 0-4 bar; display range 0-4 bar or 0-2 bar; display range 0-2.5 bar
Input and output couplings: hose fitting connect type for 4 mm (inner diameter) tubing
Status / EJECT time indicator:
- red/green LED
- red light: valve is closed (in EXTERN TIMER, CONT. operation mode)
- green light: valve is open
- Off (no light) valve is closed
Mode selection: four position toggle switch, OFF, EXTERN TIMER, CONT.
Valve switching time: 10-20 ms (dependent on tubing) / <1 ms with microJECT
Analog timer: 0.001 – 0.1 s, 0.01 – 1 s, 0.1 – 10 s or 1 – 100 s with linear control, range set by rotary switch time base selector (x0.01 s, x0.1 s, x1 s, x10 s)
