Assorted Kontes and Ace Glass 2-Neck Round Bottom Flask 14/20 Joints 100 ml Lot of 5 Flasks

Both the Kontes 294990-0100 and the Ace Glass 9464-10 are 100 ml 2-neck round bottom flasks featuring 14/20 ground glass joints. While they serve the same primary function, they are produced by two of the most reputable names in laboratory glassware, often found as assorted stock in synthetic chemistry labs. The Kontes 294990-0100 is part of the Kimble-Chase line, known for high-quality, heavy-duty laboratory glass. It is a staple for microscale organic synthesis. The Ace Glass 9464-10 is built to the same rigorous standards as the Kontes model. Ace Glass is frequently favored for its uniform wall thickness, which provides excellent protection against thermal shock. The angled neck is ideal for inserting a thermometer or an addition funnel while the center neck is used for a condenser or stirring shaft. Both brands use high-grade borosilicate glass that can withstand the high temperatures required for oil baths or heating mantles.

Used, in great condition.
