The Binary pump is designed for highest performance, GLP compliance and easy maintenance.

It includes the following features:
• Seal wash for continued high lifetime of pump seals for buffer applications.
• Solvent selection valve for method flexibility.
• Jet Weaver for optimum mixing performance with a minimum of delay volume.
• Automatic purge function for ease of use and unattended preparation of the system.
• Auto tuning of the delivery cycle for compensation of elasticity and solvent volume change effects
(compressibility, thermal expansion, mixing contraction).
• Solvent selection for optimum flow and composition accuracy.
• Fast defill function for improved intake and delivery performance.
• Two pistons in series design for increased reliability.
• High resolution piston movement control for smooth and reliable motion.

Hydraulic system: Two dual pistons in series pumps with proprietary servo-controlled variable stroke design,
power transmission by ball screws, smooth motion control of pistons for active damping.
Settable flow range: Setpoints 0.001—5 ml/min, in 0.001 ml/min increments.
Flow precision: ≤0.07 % RSD or 0.005 min SD, whatever is greater (0.2—5.0 ml/min).
Flow accuracy: ±1 % or 10 µl/min, whatever is greater.
Pressure operating range: Operating range up to 120 MPa (1200 bar), up to 2 ml/min, 80 MPa (800 bar) at 5 ml/min.
