DM 245

The DM 245 features a double grating excitation monochromator which makes it upgradeable to Absorbance, Circular Dichroism, and CLARiTY. Because of the double grating optics, the sensitivity is lower than the DM 45, however it is a more flexible model with lower stray light.

SM 45K

To study microsecond fluorescence lifetimes of metal ligand complexes, we designed a single monochromator system with high sensitivity. This elegantly simple device allows the investigator to mount a suitable excitation source laser, LED, pulse lamp, other at the sample compartment. This group at Furman needed a cryogenic flask chamber, as shown here.
