Based on the same robust design as the 215 Liquid Handler/Injector and autosampler, the Quad-Z 215 features four independent probes with variable horizontal spacing from 9 to 18 mm for access to a wide range of sample vessels. Large bed capacity liquid handler holds up to 17 microplates Accommodates many of Gilson's racks for maximum flexibility for sample transfer between tubes, vials and plates The 402 Syringe Pumps have four independently controlled syringes for use with the four independently controlled probes on the Quad-Z 215. This maximizes flexibility across all four channels The 402 Syringe Pumps accept syringe sizes ranging from 100 µL to 25 mL Optional 849 Multiple Injection Module enables automated on-line injection onto parallel HPLC systems Optional Code 300 Series SPE Racks are ideal for automated solid phase extraction applications
