Infinite F50 Absorbance Reader

Infinite F50 Absorbance Reader

The Infinite F50 and Infinite F50 Robotic absorbance plate readers, together with Magellan data analysis software, are ideal solutions for photometric measurements of ELISAs and kinetic assays in the 400 to 750 nm wavelength range. The systems’ innovative design combines eight measurement channels with long-life LED lamps for fast parallel reading and minimal maintenance costs.

Available in ROI/NI


  • Versatility In a Small Footprint


  • Deal for absorbance-based ELISAs, kinetic and multi-label reading
  • Ready for qualitative and quantitative data analysis using Magellan data analysis software
  • All major curve fittings supported


  • Reader-operated front door for easy plate loading
  • The reader’s housing can be partially removed during set-up, providing full access to the plate carrier for more straightforward teaching of the robotic arm
  • Ready for integration onto Tecan’s Freedom® EVOand Fluent® platform

Add-On Tools

LIS option

The hand-held barcode scanner included in the LIS option is a time-saving and convenient tool for reading barcoded sample or plate IDs.

It provides automated data transfer into Magellan software and data export to a LIS in ASCII and ASTM formats.


Additional filters

The standard filter configuration of the Infinite® F50 and Infinite F50 Robotic plate readers enables absorbance measurements at 405, 450, 492 and 620 nm.

Additional filters are available separately.


MultiCheck™ QC package and IQOQ services

The MultiCheck QC package for the Infinite F50 and Infinite F50 Robotic plate readers offers a fast and easy way to verify and document reliable instrument functionality over time.

The MultiCheck QC package provides an appropriate system check for installation qualification (IQ) and operational qualification (OQ).

The following key reader parameters are verified according to pass/fail criteria

  • Accuracy
  • Precision
  • Linearity
  • Plate carrier alignment
  • Positioning check of standard filters
