This delivery solution is often useful for preparative chromatography, being capable of separating high efficiency columns in a way that is fast, in both reverse-phase and normal modes. By choosing the 333 master pump for isocratic applications or a 333/334 combination for binary gradient applications, the item allows milligram-to-gram level sample mass throughout per injection of up to 15 grams. This, however, depends on the loading capacity and size. Next, the composition gradient comes with high-pressure mixing, while the solvent selection is possible on each pump with the addition of four-solvent valve.
You can also use this product to operate additional pumps in parallel, doubling the flow rate to up to 400 mL / min. Next, the flow-rate gradient, four-solvent selection, composition gradient and step gradient are all worth mentioning. The operation is quiet and durable, while the electrical input / output contacts are useful with any other associated equipment.
