The HP / Agilent 1100 HPLC series is the current model and arguably the best design in the industry because of the optimized design of the quaternary pump ensuring virtually pulse-free and stable solvent flow, with dual floating pistons in series, precisely servo-controlled. This design with variable stroke volume allows pulse-free solvent delivery and efficient mixing. An inlet-valve electronically activated and synchronized to piston stroke - eliminates vapor formation with volatile solvents and is maintenance free. With high-speed proportioning valve and pre-configured vacuum degasser, for convenient low-pressure mixing of up to four solvents and highest flexibility in solvent choices.

 Features:

• Ease-of-use - handheld control module lets you enter operating parameters fast, store methods easily and display pressure profile, diagnostics and task-oriented information.
• Durable - stainless steel, titanium, gold, ruby, sapphire, ceramics, PEEK and PTFE ensure long lifetime. Seal wash option for high salt mobile phases keeps maintenance to a minimum for lower operation costs.
• Wide flow range - up to 10 ml/min for broad HPLC work, including semi-preparative separations.
• Better for GLP - built-in leak and pressure test with graphical presentation of pressure profiles, and early maintenance feedback.

Specifications:

• Hydraulic system: Dual piston in series pump with proprietary servo-controlled variable stroke drive, floating pistons and active inlet valve
• Settable flow range: .001– 10 ml/min, in 0.001 ml/min increments
• Flow range: 2 – 10.0 ml/min
• Recommended pH range: – 12.5, solvents with pH > 2.3 should not contain acids which attack stainless steel.
• Operating voltage: 230V

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
