Capillary Head for CyBi®-Well vario
Compound Transfer Directly from Stock

  • Transfer of nl-samples in dry plates with non-contact mode
  • Prepare ready-to-use assay plates - no time consuming dilution or compound precipitation
  • Simultaneous transfer of 96 or 384 samples - in high throughput up to 500,000 samples per day
  • Highest precision fo < 10 % CV from 25 to 1000 nl
  • Saves reagent costs by extremly low dead volume
    of < 1 µl
The Capillary Head of the CyBi®-Well vario is an exchangeable pipetting head for the dry/non-contact transfer of nanoliter-samples in any type of microplate from 96- up to 1536-well format. The transfer of the samples occurs with capillaries, which are arranged in the 96- or the 384-channel magazines. This robust technology utilizes the capillary action for aspiration and a pressure impulse for the dispensing. The different types of magazines are exchangeable in a few seconds. The product program for capillary magazines covers  a volume range from 25, 50, 100, ... up to 1000 nl.  The innovative CyBio® Composer software supports  the system with a few simple commands. The Capillary Head can be used to upgrade any type of CyBi®-Well vario in order to create a complete workstation for compound handling. A complementary program of accessories as stackers or barcode-reader approves the automation and high throughput processing. The high-efficiency Capillary Wash Stations with a proven carry-over of less than 0,05 % offer a liquid transfer without relevant cross-contamination.
