K2

---

The K2 family of instruments offers a solid, well-proven approach to fluorescence and phosphorescence instrumentation even for the most demanding research applications.

K2 is a frequency domain fluorometer with picosecond resolution. Its optical design and automatic instrument control are state-of-the-art for steady-state and time-resolved fluorescence measurements.

User-Friendly Software

K2 includes Vinci – Multidimensional Fluorescence Spectroscopy, a powerful software package that provides several ready-to-use routines for reliable, user-friendly acquisition of complex fluorescence data:

• Spectra (excitation, emission, synchronous, time-resolved and polarization)

• Measurements at fixed wavelengths (intensity and polarization)

• Slow and fast kinetics

• Time-resolved measurements (lifetimes and rotational correlation times)

 

Key Features

• Millisecond to picosecond lifetime measurement capabilities

• Complete lifetime scans in less than one minute on routine samples with proprietary FastScan™ technology

• A compact footprint and a short optical pathlength for maximum sensitivity and efficient light coupling into the sample

• T-format and parallel beam design for fast and precise polarization measurements

• Full automation of instrument components (cuvette holder, polarizers, shutters, filterwheel, monochromators and stirrers)

• PC-controlled integration of temperature bath, titrator, stopped-flow apparatus and pressure pump

• Fast kinetic measurements with one millisecond resolution in photon counting mode

• 80 MHz pre-amplifier discriminators delivering linearity up to over eight million counts per second on each channel

• Flexible instrument configuration

• Upgradable with ozone free lamp, laser diodes, continuous- wave (CW) and TI:Sapphire lasers
