Gilson’s 333/334 Prep-Scale HPLC Pumps are your delivery solution for preparative chromatography. They are capable of fast separations with high-efficiency columns in normal- and reverse-phase modes. Choose the 333 Master Pump for isocratic applications or a 333/334 combination for binary gradient applications.
Cat. No. GF-38103331 (333), GF-38103341 (334)
Features:
- Milligram-to-gram-level sample mass throughput per injection; up to 15 g depending on column size and loading capacity
- Composition gradient with high-pressure mixing: 333-334 Binary System (third pump for ternary). Solvent selection on each pump with addition of four-solvent valve (up to eight solvents)
- Ability to operate additional pumps in parallel to double the flow rate up to 400 mL/min
- Control from 333 Master Pump: flow-rate gradient, four-solvent selection and step gradient (additional valve), composition gradient (one or two additional pumps), sample-injection pump, UV/VIS detector, and electrical input/output contacts with any other associated equipment
- Quiet operation, durable design
- Control 33X Pumps and an entire preparative HPLC system via UniPoint™ LC System Software
- Stackable to conserve bench space
