Sensitivity - The compact design optimizes the light path so that the sample compartment receives the maximum possible excitation light and the detectors collect the fluorescence signal with high efficiency. 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 in the instrument control window where the user has direct 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 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 spectrometer 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.
