Product Description
Run overhead stirrers smoothly through a ground joint with a bearing honed for a close fit on the shaft. The precise bore and built-in lubricant reservoir reduce wobble and friction, so stirring stays steady through long reactions while vapor loss around the shaft is kept low.
This listing is for Kimble catalog number 781001-2440: Precision Stirrer Bearing. The bearing is honed for a 10 mm OD shaft and has an integral 24/40 Standard Taper joint for use with a wide range of flasks. Overall length is about 120 mm. It is made from 33 expansion, low extractable borosilicate glass meeting USP Type I and ASTM E438, Type I, Class A. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
