Laboratory rack and shelf for funnel-shaped glassware

摘要

A wire frame shelf with longitudinally displaced conically- shaped, coaxial, funnel holders with an elongated vertical front clearance space on each funnel holder. The funnel holder is larger in the upper portion to receive and embrace a tapered glassware device in the axially displaced circumferential opening. A bight at the holder bottom formed by the crossing of the two U-shaped supports may act to support protuberances on some glassware devices and to protect protuberances on other glassware devices. Thus, the opening and bight provide a glassware device with a protuberance with horizontal support, vertical stability, protection from accidental jars, and a convenient resting place for the protuberance on the glassware device.
