Agilent 1100 Capillary Pump (G1376A)
This Agilent 1100 Series G1376A ( G1376 A / G 1376 A / G 1376A ) Capillary Pump ( Cap Pump) is in excellent condition.
This system, based on the reliable Agilent 1100 Series HPLC system, uses a unique pump technology that optimizes the system for capillary LC, offering a high level of sensitivity and reproducibility.
The Agilent 1100 Series capillary pump incorporates an electronic flow control (EFC) that measures and controls the actual flow rate, rather than depending on calculations. This 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.
A unique pump design offers better control and flexibility of low flow rates. This pump is ideally suited for capillary LC and LC/MS applications, like bio-pharmaceutical research, where sample volumes are limited and higher sensitivity is essential.
Features:
- Electronic flow control (EFC) – measures and controls the actual flow rate, rather than depending on calculations.
- 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– through the use of microvolume components
