SCIENION’s non-contact proprietary dispensing technology takes microarray spotting to the next level. The technology, as patented by SCIENION, is called sciDROP PICO, and covers dispensing a liquid sample from 10 pL* to 800 pL per drop.

This non-contact technology offers a number of benefits over contact spotting.

  •     Homogenous spot morphology
  •     No damage to sensitive surfaces, as can result from contacting metal pins
  •     Dispensing into very small cavities
  •     Drop volume is fully controlled by implementing a proprietary vision-based algorithm

In combination with sciDROP NANO, the total volume range between 10 pL and 100 μL is covered by a single sciFLEXARRAYER instrument.

SCIENION’s sciDROP PICO is a state of the art non-contact dispensing technology based on piezo driven pulses on an inert glass capillary.

This enables accurate and precise droplet deposition under various conditions. 

All Piezo Dispense Capillaries (PDCs) aspirate and dispense liquid at the picoliter scale.

The sciDROP PICO option, together with SCIENION´s surface coating technology, provides access to a broad field of applications with high accuracy and precision dispensing a wide range of liquids:

We find the best PDC size and coating combination for your application!

  • Benefits of sciDROP PICO

    • Gentle acoustic dispensing of samples, no shear stress
    • Living cells are successfully dispensed
    • No added glycerol is needed in the system liquid
    • Precise drop volume control with unique visual detection
    • Absolute zero dead volume
    • No crystallization of sample inside the tip due to a round orifice
    • No satellite drops due to full drop ejection parameters control
