  • 1D and 2D integrated barcode readers for full reagent and samples traceability

Standardized results

  • High-precision pipetting
    • Capacitive level sensor for reliable pipetting performance
    • From 5μl to 1000μl pipetting volume
  • Standardization of the washing phase
    • Separate channels for dispensation and aspiration of the washing liquid
    • Two different washing modes for cells and tissues (multi drop or continuous flow) 
  • Avoid carry over contamination
    • Metal needles, (not coated), washable internally and externally

ZENIT FLOW + ZENIT FAST: A winning combination in IIF slide preparation and scanning

ZENIT FLOW is designed to work with ZENIT fast to increase lab productivity thanks to parallel processing and scanning. This configuration can be easily adapted to any routine due to exceptional flexibility and modularity.

Parallel slide processing and scanning with no lead time

30-slide workload of ZENIT FLOW can combine with the ZENIT fast series-load batches, for true parallel operation of devices to increase overall throughput and minimize the time-to-result.


  • One Single PC working station to manage both ZENIT FLOW and ZENIT fast
  • Multiple ZENIT FLOW and ZENIT fast units can be connected to one single PC working station
  • ZENIT Hub centralised middleware ensuring full traceability and Bi-directional LIS connection
  • Throughput can be increased and tailored according to the user's needs
