We have recently had a design change to our Luer stopcocks. While this sleek design is consistent with the look and functionality of today’s fittings and valves, probably half the users will like them and the other half will hate them. Unfortunately for the latter half, the old style has been discontinued and the molds no longer exist. There is good news, however. The new design uses less material and is less expensive. The handles are easier to grip and adjust, and the ports conform to ISO 594-1 and 594-2 standards. Plus, a couple of new configurations have been added to the line so you have more options. These new stopcocks still accomplish the same thing they always have, but they conform to the new standards and look and feel better than the old design.
