Description
LabSTAF Laboratory PhytoPP
LabSTAF Laboratory PhytoPP
The Chelsea Technologies Single Turnover Active Fluorometry (STAF) is for measuring phytoplankton primary productivity (PhytoPP)
LabSTAF Is the next generation of STAF-based primary productivity instrumentation to measure algal activity. The system incorporates unparalleled sensitivity with a wide dynamic range, allowing for measurements in all environments: from reservoirs and lakes to open ocean.
LabSTAF AT A GLANCE
- Benchtop instrument to measure primary productivity using fluorescence, giving data for over 50 useful parameters within 15 minutes
- LabSTAF includes a peristaltic pump, solenoid unit and flow-through stirrer unit to provide for mixing, sample exchange and a periodic cleaning cycle.
- Also included is a Surface Go 2 laptop, pre-installed with the regularly updated RunSTAF software.
- Data from LabSTAF is interpreted and analysed internally in the included Surface Go

Solutions
WHAT’S THE PROBLEM?
Traditional methods of measuring primary productivity (algae) make acquiring good data for ocean science challenging:
- Satellite remote sensing methodology is the broadest large-scale method, but produces large errors, requires validation and is unable to probe below the surface
- Traditional methods such as C14 fixation are slow, expensive laboratory-based processes requiring handling and training protocols for radioisotopes, with extremely long incubation times of 8-24hrs.
WHATS THE SOLUTION?
LabSTAF, using Single Turnover Active Fluorometry (STAF) technology, provides a revolutionary new method to enable large-scale PhytoPP assessment. LabSTAF is the first of a range of STAF-based products from Chelsea technologies enabling large-scale analysis:
- Monitoring phytoplankton primary productivity using latest technology
- Unparalleled sensitivity allowing for measurements in extreme oligotrophic water
- Fully automated acquisition for continuous measurements
- Wide dynamic range providing reliable measurements in open oceans and lakes
- Advanced corrections as standard seven waveband excitation, baseline subtraction
- Compact and robust portable unit ideal for research vessels and outdoor locations
