We are best known for our line of circular dichroism spectrometers with a variety of accessories. We now offer a fluorescence detection system for the analytical ultracentrifuge. For many years we have offered a hematofluorometer for measuring zinc protoporphyrin levels, an indicator of anemia and lead poisoning.
