SPLITLESS Nano/Micro-UHPLC System

Zirconium Nano- and Micro-UHPLC System

Zirconium pump

Prolab's Zirconium Ultra Nano- and Micro-UHPLC System is a binary gradient pump with a vast range of split-less flow rates from 4 nl/min to 500 μl/min at 1000 bar (15,000 psi). Methods can be scaled from conventional 2.1 mm ID columns down to 75 μm ID while using the same pump all the way, thereby achieving more than 700x sensitivity gain. The high-resolution linear piston drives and optional flow sensors allow for highly precise gradient control at the lowest flow rates and highest pressures. Thanks to a unique pump head and active valve design it is now possible to completely automate all preparative and pre-compression of solvents for short equilibration times, and flow-through purging for automated solvent exchange and air removal. Comprehensive software support packages complete a capillary/nano  UHPLC pump which is unmatched on the market today.
