VICI's new combination nanovolume pump/injector is available in multiple configurations. The single pump model has a flow rate of 1 nl to 100 µl per minute at pressures up to 15,000 psi, with sample volume as small as 10 nL. The gradient system has two pumps with maximum capacity of 35 µl each, delivering 5 nl to 100 µl/min at up to 8,000 psi. Soon to be released is a three pump design available as a continuous flow or gradient system rated at 15,000 psi. The single, dual, and triple units weigh 3, 5.5, and 8 pounds, respectively. The controller is an additional 3 pounds.
