Features of Accela 1250
Innovative Force Feedback Control (FFC)* technology enables the delivery of accurate and precise flow and gradients under all operating conditions:
- An extremely low pulsation (lower than 0.5 bar amp.) without the need of a pulse dampener guaranties smooth detector baselines
- Continuously calibrates valve timing and pumping efficiency based on the measured compressibility of the actual solvents
- Provides the flexibility of a quaternary pump with oustanding performance
- Maximum flow rate of 2mL/minand a maximum operating pressure of 1250 bar with only 65µL of delay volume, making it optimal for U-HPLC applications
