- Constant and pulseless flow at the outlet
- Constant suction of solvents and very low residual pulsations (for "TRIX" pumps)
- 4 models of pump available
- Built-in manual purge valve
- Cleaning discs
- UV/Vis detector with Armen housing available (additional module)
- Multi-valves fraction collector available (additional module)
- Biocompatible version available
- Low maintenance needs


Pump

Two similar pumps (characteristics of each pump)

(Flow rate range - Max. Pressure)
5 to 250 mL/min - 250 bar (3 625 psi)
10 to 500 mL/min - 125 bar (1 813 psi)
10 to 1000 mL/min - 125 bar (1 813 psi)
10 to 2000 mL/min - 100 bar (1 450 psi)

2% accuracy
Repeatability better than 0.5%
