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
