| The UltiMate® 3000 is equipped with the Dual-Gradient Micropump that allows for two independent ternary low-pressure gradients: One microgradient (from 50 µL/min–2.5 mL/min) and one nanogradient (down to 50 nL/min) delivery. Up to six solvents can be used for gradient applications. Ruggedness and reliability are ensured with an active rear-seal wash system and continuous monitoring of piston seal tightness.
The UltiMate 3000 Nano, Cap, and Micro system uses an integrated active flow splitting system: UltiFlowTM technology (patented). This innovative technology preserves a constant flow, independent of solvent composition, and column backpressures. This innovation significantly improves the reproducibility of gradients and flow accuracy as compared to passive flow splitting approaches. Pre-split gradient formation offers various advantages over splitless nanoflow gradients. Mixing is more homogeneous, and gradient delay is minimized. Even using lowest flow rates, fast changes to the gradient profiles are possible. - Wide flow rate range: 50 nL/min up to 2.5 mL/min
- Dual-gradient pump with 2x independent ternary gradient delivery [more]
- Active rear seal wash system
- Superior gradient accuracy
- Low stroke volume of 20 µL
- Biocompatible option
