Our graduated cylinders of translucent white polypropylene are just like their glass cousins, except that these are less expensive, less likely to break, not as heat resistant and, of course, not at all flame resistant. They have pouring spouts, and large bases for stability. The graduation increments/total volume are shown below in milliliters.

We have obtained a large number of real natural corks, mostly surplus with a few fill–ins bought commercially. They range across the popular sizes used in science labs to seal vessels (drill your own holes for glass tubing, etc) and to use as floats. Or just use them to seal bottles that don’t have closures or cry out for a decorative seal.
