Import Tips

Provide excitation/emission wavelength specifications confirming UV/visible optical radiation for fluorescence chemical analysis

Distinguish from medical flow cytometers by specifying laboratory analytical vs patient diagnostic use

EPA compliance documentation required for environmental monitoring units; pitfall is missing method validation certificates
