PC1 is a highly sensitive, compact, computer-controlled Photon Counting Spectrofluorimeter designed for applications in physical chemistry, biochemistry, physiology, neurochemistry, molecular biology, environmental analysis, and immunoassay research.

Key features of PC1 include:

  • Sensitivity
    The compact design optimizes the light path so that the sample compartment receives the maximum possible excitation light. The end result of the compact design is an instrument with an outstanding ability to measure fluorophores with very low quantum yields.
  • Full Automation
    Instrument control and data acquisition are PC-controlled through Vinci. All active instrument components and integrated external devices are displayed on the Instrument Control Window in Vinci. From here, the user has direct remote control over all devices and accessories.
  • Integration of External Devices
    PC1 has the capability to integrate external devices such as a stopped flow accessory, temperature bath, pressure pump, and a titrator. Any of these devices can be directly controlled through Vinci.
  • Data Reduction Management
    Vinci - Multidimensional Fluorescence Spectroscopy software acquires data in ASCII format for maximum compatibility with other software packages. Data files can be stored directly on other workstations connected to a local area network.
  • Upgradability
    PC1 is fully upgradable to a time-resolved fluorometer to acquire time-resolved fluorescence and phosphorescence measurements with picosecond resolution. A variety of light sources and other accessories are available for a broad range of applications.

Measurement Examples from PC1

Alexa Fluor 555 in Water

Excitation polarization spectrum of Alexa 555 with a polarization value of P = 0.283 for the recommended excitation range for polarization measurements. Data was acquired on PC1T using a 300W Xenon lamp.


The spectrum was acquired using the PC1 with excitation wavelength set at 380 nm. Emission was scanned from 400 nm to 600 nm. Monochromators bandwidth was 8 nm. Images can be exported in jpg, gif, tiff, png, bitmap, and Windows enhanced meta file.
