Agilent Cary 3500 Multicell UV-Vis

Price Range: $20,000 – $26,000 USD

Best For: Complex kinetics and temperature-sensitive experiments.

Category: Best For Speed / Kinetics

The Agilent Cary 3500 continues to represent a paradigm shift in optical design by utilizing a xenon flash lamp and a unique simultaneous scanning architecture. Instead of moving a single beam sequentially across samples, the Cary 3500 measures all eight cell positions (7 samples + 1 reference) at the exact same moment. This design eliminates time-lag errors in kinetic studies and dramatically increases laboratory throughput. The system has no moving parts in the optical train, which enhances stability and minimizes maintenance requirements over the instrument's lifespan.

Key Specs

• Throughput: 8 channels simultaneous measurement

• Data Collection Rate: Up to 250 points/second

• Lamp Life: 10-year warranty (Xenon flash)

• Photometric Range: Up to 4 Abs

• Temp Control: Air-cooled Peltier (0–110°C)

Performance & Applications This instrument is particularly suited for enzymology, biochemistry, and material science labs where reaction rates must be monitored under strictly controlled thermal conditions. The integrated air-cooled Peltier system allows for rapid and precise temperature ramping without the need for external water circulators, reducing bench clutter. Researchers conducting denaturation/renaturation studies or competing reaction analysis benefit from the ability to run multiple variables simultaneously under identical conditions, ensuring high experimental reproducibility.
