74-MSP Mirror Screw Plugs

The 74-MSP Mirror Screw Plugs were designed for use with our Fluorescence cuvette holders, such as our CUV-ALL-UV and CUV-FL-DA. A mirror plug screws into a collimating lens port on the cuvette holder to redirect energy back to the sample or back into a collimating lens. To increase signal collection for fluorescence measurements when using the CUV-ALL-UV, add a pair of 74-MSP Mirrored Screw Plugs. These 0.3" (7.5 mm) UV-enhanced aluminum-coated reflection mirrors connect to the CUV-ALL-UV to provide optimal signal reflection. One mirrored screw plug collects the fluorescence that would otherwise be lost; the second screw plug works to reflect the excitation energy back through the sample. 

The CUV-FL-DA includes two 74-MSPs. (See image at right.) The CUV-ALL-UV does not come with any 74-MSPs. If you intend to use the CUV-ALL-UV for fluorescence, we recommend ordering two 74-MSPs. The CUV-ALL-UV 4-way Cuvette Holder is equipped with fiber optic couplings at each of four quartz f/2 collimating lenses, which couple to optical fibers to either read or illuminate the sample. When used in a fluorescence measurement, you would remove two of the CUV-ALL-UV collimators and replace them with the mirror plugs to enhance your fluorescence signal.
