Fluorescence Models for Clear Solutions
There is a sturdiness, a robustness, a timeless quality to the OLIS fluorimeters that tells you from the first that “This is an instrument I’ll use forever.”
Few people think of OLIS first for fluorimeters, but owners of these three instruments will tell you they “love” theirs, 5, 10, 15, 20 years after purchasing one. You will, too.

This August 2025 photograph shows Dr. Himali Jayathilake with her 18-year-old OLIS DM 45 at Mount Holyoke College. Our Customer Support Engineer, Elisabeth Millsap, was astonished when she arrived for a system-verification visit and found this “splendidly cared for” instrument awaiting her. The system – upgraded once a few years ago to Win 10 -- easily passed all performance tests. Dr. Jayathilake shared: "I was thrilled to hear from Elisabeth that all is well with our instrument and I am excited to hear more about the possible upgrades." Upgrade possibilities include upcycling it to become an OLIS DSM 45 for anisotropy and CPL or a CLARiTY 45 for turbid sample studies.
