Quartz Window Flow Cell
SKU / Part #: 13307800-801
The Quartz Window flow cell features a quartz window in each of the fluidic pathways to enable SPR experiments combined with Photochemistry/ Fluorescence.
The Reichert quartz window flow cell facilitates experiments combining SPR with photochemistry, imaging fluorescent labeled molecules on the sensor surface by direct excitation and surface plasmon field enhanced fluorescence spectroscopy. Surface plasmon field enhanced fluorescence spectroscopy is an extremely sensitive and effective tool for detecting and quantifying biomolecular binding. This technique depends on excitation of a fluorophore near the gold sensor surface of an evanescent field. Resonance of p-polarized light with surface plasmons (oscillating electrons) in the gold layer produces the evanescent field.
