Piezoelectric Nozzles

(Brochure)

The patented piezo microdispensers are created from microstructured silicon and glass chips, tightly connected by anodic bonding. We offer a variety of packaging and design that allows for integration in a whole range of customer-specific laboratory systems providing non-contact dispensing.

These actuators are piezoelectric ceramics glued onto the outside of a thin silicon membrane. Upon application of a voltage, they go out of shape in a preferred direction. This deflection is transferred to a 0.8ul pump chamber filled with fluid and results in the formation of a tiny droplet that is ejected from the nozzle at a speed of 1 - 5 meters per second. This process can be repeated indefinitely.

The dispensers adhere to the "Drop on Demand" principle; this means precise dosage, because each electrical pulse generates exactly one droplet. Bursts with a predefined number of drops at a certain frequency are freely selectable and can be used to dispense varying amounts of fluid or draw lines.

  • Delivery of perfectly spherical droplets
  • Multiple pipette types producing different droplet volumes e.g., SPIP (approx 1 nanoliters) and PICPIP (0.1 nanoliters)
  • Defined bursts on mouse click or by hardware triggering
  • Burst mode or continuous dosage
  • Ready to use immediately after plugging the control device into the PC
  • Special designs (multi-channel and heatable pipettes) available
