Yamato PiCOEXPLORER Photo Absorbance Sensor



A portable absorptiometer that uses white LED as light source.

Operation and features

  • Palm-size absorptiometer made of silicon resin (PDMS)
  • The highly sensitive yet extremely compact design of PiCOEXPLORER is a
    result of the breakthrough Silicone Optical Technology (SOT)
  • Smarter data management
    Measurement results can be verified on a smart phone or tablet by
    downloading a special application that uses bluetooth communication.
    Raw data (absorbance, concentration, intensity) can be output to a PC in
    excel format for easy data processing.
  • Measurements can be taken directly from unopened PCR tubes, preventing
    contamination risk and sample loss


  • Measurement of bacterial turbidity
  • Quantification of protein (BCA method, Bradford method)
  • Measurement of antioxidant activity
  • Amino acid measurement (ninhydrin method)
  • Quantification of glucose
  • Environmental water analysis
  • Analysis of heavy metals
