A series of multi-socket lids for use with the Quickfit range of wide neck reaction flasks and culture vessels. They allow introduction of a great variety of standard Quickfit equipment for stirring, temperature measurement, aeration and general distillation procedures. The parallel side neck can be fitted with a multiple adapter so that larger dropping funnels can be used. Lids with a single socket neck are of use where simple extraction, refluxing or mixing only are required.
