Colorwatcher

Colorimetric Array Reader

Colorwatcher is a compact and portable instrument designed for imaging colorimetric arrays (for example, DNA, protein biochips). The instrument by standard operates in brightfield and darkfield illumination modes with bottom and top illuminations respectively. The instrument is able to work with 96-well plate, a 12 x 8 well strip, as well as microscopic glasses (placed in a special adapter). The device is equipped with a highly sensitive CMOS camera. The instrument has an automatic mechanism of 96 well plate ejection outside the body. The instrument can operate with a 20V portable lithium-ion battery, which makes the device usable in the field studies or point-of-care. The compact design allows the device to be carried in the hand luggage of the aircraft.

  • End-User interface, with simplified interface, where user just chooses assay, loads samples and gets results
  • Automated image acquisition, analysis and report generation (up to 12x12 array in 96 well plate in under 3 minutes)
  • Automatic array finder via machine learning and image recognition
  • Grid lay-outing (Manual and Automatic)
  • Password protected Assay Developers interface with full access to the vast software parameters
  • Analysis of images by the average/median intensity of the spots
  • Qualitative/quantitative analysis of the arrays
  • Creating Qualitative/quantitative analysis assays
  • Quantitative assays with 4/5 parameter logistics functions, etc.
  • Setting multi level interpretation thresholds for different type of samples in the same well (e.g. tolerance to egg and lettuce)
  • Reports available in PDF, CSV, EXCEL files
  • Control of camera exposure, gain, XYZ kinematics.
