PTFE-coated magnetic stir bars for use with magnetic stirrers and hot plates. Single-size packs of 10 pcs come in lengths from 10 to 40 mm. Two 8-piece assorted sets in a storage box are also offered: cylindrical (Type C) and olive/oval (Type A). The bars fit beakers and flasks from small to large volumes.
Key Features
The PTFE coating resists high and low temperatures, acids, alkalis and organic solvents.
The smooth, low-friction surface resists sample adhesion and does not contaminate reagents.
The central pivot ring stops the bar rolling or wandering, so stirring stays stable.
Sturdy and wear-resistant for repeated heating in thermostatic, oil-bath and water-bath work.
