The New Standard in
Portable Fluorometers
For years, Opti-Sciences has offered the successful, highly portable, compact GFL liquid fluorometer for field studies. The new GFL-1a still provides easily interchangeable filter sets, easy conversion from discrete measuring samples to a flow through chamber, a water resistant case, and very high sensitivity. New features include additional memory storage, convenient SD card memory modules, USB port, color graphics display, and a longer lasting NiMH battery. Like its predecessor, the GFL1-a is a lightweight, easy to use, field instrument.
