- Features a robust two-channel, dual-plunger in-series design for comprehensive solvent delivery functions.
- Capable of generating gradients through low-pressure mixing from four individual solvent channels.
- Achieves virtually pulse-free and stable solvent flow with variable stroke volume.
- Pump assembly can generate pressures up to 600 bar, efficiently metering solvent and delivering it to the high-pressure side.
- Integrated 4-channel vacuum degasser built into the quaternary pump to ensure efficient degassing of solvents.
The Agilent 1260 Infinity HPLC G1311B Quaternary Pump is based on a two-channel, dual-plunger in-series design which comprises all essential functions that a solvent delivery system has to fulfill, generating gradients by low pressure mixing from four individual solvent channels. The G1311B ensures virtually pulse-free and stable solvent flow via the variable stroke volume. Metering of solvent and delivery to the high-pressure side are performed by one pump assembly, which can generate pressure up to 600 bar. Degassing of solvents is accomplished with an integrated 4-channel vacuum degasser built into the quaternary pump. Solvent compositions are generated on the low-pressure side by a high speed proportioning valve.
All of our equipment is fully tested to perform at factory
