Brand and Model: DUAL-PAM-100 Fluorimeter (Walz)

Description:
Modular system for the simultaneous measurement of chlorophyll fluorescence and the redox state of Photosystems I and II (PSI and PSII). It is used for studies of photochemical efficiency and rapid kinetics in plants, algae, and suspension samples. It offers highly sensitive measurements with microsecond temporal resolution.

Technical Specifications and Components:
• DUAL-C control unit with USB interface and internal memory (4 MB, 256,000 data points)
• Light sources: Blue (460 nm) and red (635 nm) actinic LEDs, far-red (720 nm)
• Continuous illumination intensity: Up to 3000 μmol m⁻² s⁻¹ PAR
• Saturation pulses: Up to 200,000 μmol m⁻² s⁻¹ (adjustable from 5 to 50 μs)
• Dual detection channel (PIN photodiode or photomultiplier) for fluorescence > 700 nm and P700 (830/870 nm)
• Maximum temporal resolution: 30 μs
• Compatible with gas exchange units, measurements on leaves or suspension cultures
