Mixed Set Of Three Laboratory Glassware Pieces

Three different laboratory glassware pieces: a pear-shaped flask with a shaped glass stopper and retaining hooks; a cylindrical glass assembly with a stopcock and multiple ground joints; and a bottle with two long necks and side connections, without stoppers. Clear glass, matte ground joints, signs of use and localised deposits; an old inventory label remains on the cylindrical piece. Varied detail props for laboratory and chemical industry sets. Leak-tightness has not been tested.
