Z650 High Sensitivity Fluorometer

Starting from $21,900

The Z650 High-Sensitivity Fluorometer with its detection limit of 1 ng Chl/l allows measuring of fluorescence induction and of QA reoxidation kinetics with pico-molar chlorophyll concentrations. The typical experimental material is natural water with phytoplankton.

The core of the instrument is an integrating Teflon sphere containing the liquid sample. The optical ports of the sphere are supplied with three sets of light-emitting diodes and with an avalanche photodiode detector. As an option, the instrument can be supplied with a second detector to capture fluorescence transients in alternative spectral band. Contact Qubit for your specific needs. Measuring flashes, single-turnover saturating flashes, and continuous actinic light are of blue color, λmax=455 nm. Light intensities and timing are software controlled separately for each LED set.

Typical Samples:

Natural water with phytoplankton
Chloroplasts & thylakoids
