We typically have used and reconditioned pumps in stock from leading manufacturers like Cole-Palmer and Watson/Marlow.
The Agilent Technologies 1200 Series (G1310B) 1260 Infinity Isocratic Pump is a HPLC workhorse for demanding QA/QC and routine applications, designed to provide virtually pulse-free and stable solvent flow. This delivery principle allows variable stroke volume optimized to selected flow rate. The broadened pressure range with maximum pressure of 600 bar allows the use of small particle size columns, longer columns, or alternative solvents of higher viscosity. Additionally, the G1310B is the ideal pump for GPC/SEC applications where run-to-run and day-to-day precision of retention times are important.

1260 Infinity - G1311B
The quaternary pump comprises an optional solvent cabinet, a vacuum degasser
and a four- channel gradient pump. The four- channel gradient
pump comprises a high- speed proportioning valve and a pump assembly.
It provides gradient generation by low pressure mixing. A solvent cabinet
provides enough space for four one- liter bottles. An active seal wash
(optional) is available when the quaternary pump is used with
concentrated buffer solution

Specifications:
Can be sold as an individual component or as part of a complete stack
Features:
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.
