Overview
A chemist who stirs magnetically gets three Pyrex Griffin beakers in graduated sizes and a PTFE stir bar. Each beaker has a beaded rim, a spout and a double scale.
The beaded rim and uniform wall thickness are made to withstand daily handling. Only one stir bar comes with the three, and no dimensions are listed.
Who it's for
Teaching and general chemistry labs using stir plates. Precise measurement needs volumetric ware.

Performance notes
The PTFE coated stir bar spins in the liquid under a stir plate, and its pivot ring cuts friction at the glass. Borosilicate walls handle heating and cooling, and the spout directs the pour.
