Easy scaleup from analytical to preparative
Dual-piston pumps for easy linear transposition from analytical to preparative HPLC methods on 4 to 20 mm I.D. columns packed with high-efficiency stationary phases. The 331 master pump can control the 332 in gradient systems, solvent selection, sample-injection pump, UV/VIS detector, and electrical input/outputs with any other associated equipment.
The repeatability for gradient is < 0,7% over the entire flowrate range 0,5 to 50 ml/min and 600 bar pressure. The Adjustable Volume Dynamic Mixer (AVDM™) 260-2260 µl makes it easy to switch from analytical to preparative applications while maintaining a fast gradient response and homogeneous mixing.
