Yamato PiCOEXPLORER Photo Absorbance Sensor



The Yamato PiCOEXPLORER PAS-110-YU photo absorbance sensor, weighing just over 200g, is a sleek, compact, and highly sensitive absorptiometer that enables efficient concentration measurement analysis. Built with intuitive bluetooth connectivity, the PiCOEXPLORER absorptiometer allows you to easily control the unit from your mobile device for uninterrupted workflow and increased productivity. In addition, improve your data management with seamless data transfer between your PiCOEXPLORER and your smartphone or tablet.

The Yamato PiCOEXPLORER Photo Absorption Sensor also allows you to take concentration measurements efficiently from unopened PCR tubes. Moreover, the Yamato PiCOEXPLORER PAS-110-YU absorptiometer eliminates the use of pipettes for reduced labor, time, and contamination risks for applications with single PCR sample measurements.

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
