Agilent 1100 Capillary Pump

Boasting Agilent reliability, this 1100 Series capillary pump uses a unique pump technology that optimizes the system for capillary LC, offering a high level of sensitivity and reproducibility. The pump incorporates an electronic flow control (EFC) that measures and controls the actual flow rate, rather than depending on calculations, and assures flow rate stability throughout the analysis. The pump provides flow rates from 1µl/min up to 100µl/min, with full gradient capability for capillary LC and 2.5ml/min in normal mode for a wide range of flexibility. This capillary pump is ideally suited for capillary LC and LC/MS applications, such as bio-pharmaceutical research, where sample volumes are limited and higher sensitivity is essential. This Agilent 1100 Capillary Pump (G1376A) comes expertly refurbished from GenTech Scientific.

Features:

• Electronic flow control (EFC)
• Flow rates from 1 µl/min up to 100 µl/min, with full gradient capability for capillary LC and 2.5 ml min in standard mode for a wide range of flexibility
• Retention time (RT) stability – independent from column back pressure for maximum performance
• Accurate flow rates – even with solvent mixtures
• Automatic purge valve
• Low delay volume
