Two-Neck Laboratory Glass Apparatus With Shaped Attachments – Set Of Three

Three similarly constructed laboratory glass assemblies, each with a rounded two-neck bottle, ground-joint pear-shaped attachments, dip tubes and a bent connecting section. Likely intended for gas handling or gas analysis. Clear glass surfaces, matte ground joints and signs of use. A distinctive group for laboratory and chemical industry sets. Leak-tightness has not been tested.
