Automated sample processor Zenit Flow

dilutiontitrationwashing

Product overviewZenit Flow is an automated indirect immunofluorescence (IIF) slide processor designed for laboratory workflows, performing sample dilution, dispensing, washing and coverslip mounting for complete slide preparation.

System capacity

• Up to 240 samples: 8 × 30-tube racks
• Up to 30 slides: 2 × 15-slide racks
• Up to 384 wells for dilution and titration: 4 × 96-well plates (1.2 mL volume)

Scalable throughput

• ~1 h for 5 × 12-well slides
• ~2.5 h for 15 × 12-well slides
• ~5 h for 30 × 12-well slides

Optimized workflow

• Automatic sample pre-dilutions from different primary tubes within the same analytical session
• Three probes: two precision dispensing needles and one aspiration needle to accelerate slide preparation
• Slides are fully mounted at the end of the process, including reagent addition and coverslip placement
• Open configuration supports multiple IIF assay setups
• Automatic reagent volume consumption calculation
• 1D and 2D integrated barcode readers for reagent and sample traceability

Standardized results

• High-precision pipetting
  • Capacitive level sensor for reliable liquid detection
  • Pipetting volume range: 5 μl – 1000 μl
• Standardized washing phase
  • Separate channels for dispense and aspiration
  • Two washing modes for cells and tissues: multi-drop or continuous flow
• Carry-over control
  • Metal needles (uncoated), washable internally and externally to reduce contamination risk

Modularity

• Single PC workstation can manage both Zenit Flow and Zenit Fast units
• Multiple Zenit units can be connected to one workstation for centralized control
• ZENIT Hub middleware for full traceability and bi-directional LIS connection
• Throughput can be scaled according to laboratory needs

Zenit Flow + Zenit FastZenit Flow is designed to operate in parallel with Zenit Fast for increased productivity: slide processing and scanning can run concurrently with no lead time, enabling higher overall throughput.
