| | | | Dual-Gradient Micro Pump |
| The Dual-Gradient Micro Pumps are the heart of the UltiMate® 3000 x2 Dual Micro HPLC Systems and make advanced chromatographic techniques a realistic and practical option for small-bore column (1–3–mm i.d.) applications. The dual-gradient pumps are particularly suitable for research and routine laboratories that would like to increase sample throughput, achieve higher chromatographic resolutions, or automate tedious sample preparation steps like analyte enrichment or matrix elimination. The dual-gradient micro pump is available in a standard version or a biocompatible version for life science laboratories. - An dual-gradient pump incorporates two ternary gradient pumps in the footprint of a single LC system
- Accommodate two different applications on an x2 dual system with different solvents and columns, and switch between them without re-plumbing the system [more]
- Supports a wide operating flow rate range from 10 μL/min to 2.5 mL/min, pressures up to 50 MPa (7250 psi), and a flow rate accuracy of +0.25% at 200 μL/min
- SmartFlowTM technology that insures consistent flow rate precision and retention time reproducibility, with a system delay volume of 230 μL
- Achieve up to 100% higher sample throughput for validated methods using Tandem LC or Parallel LC operational configurations [more]
- Simplified setup and operation through Chromeleon® wizards and system control
