Five key features make the PC1™ Photon Counting Spectrofluorimeter the most modern instrument in its class:

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, flash lamp, pressure pump, and a titrator. Any of these devices can be directly controlled through Vinci.

Data Reduction Management

Vinci - Multidimensional Fluroescence Spectroscopy software acquires data in ASCII format for maximum compatability 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.
