  • Analog and Digital PMT
  • LCD Readout Display
  • 1 Inch Filter Holder


The PTI D-104 photometer incorporates an eyepiece to visually observe the cells on the microscope stage. By adjusting a pair of vertical and horizontal apertures in the field of view, a small number of cells, a single cell, or even a portion of a cell can be isolated for measurements. An optional camera mount can replace the eyepiece for digital visualization. After identifying the area of interest you wish to measure, simply toggle the built-in flipping mirror from ‘view’ to ‘measure’ to direct the emission from the microscope through an interchangeable filter to the photomultiplier tube for photon counting or analog detection.

For dual-emission probes, PTI offers a dual detection solution by mounting a second detector to the D-104 photometer. A dichroic beam splitter is placed in the photometer to direct the appropriate emission wavelengths to each detector for simultaneous dual detection readout.

Product Family: Photon Technology International, D-104
