Product Description
Small-scale reactions still need steady, well-sealed overhead mixing. This semi-micro stirrer assembly brings precision stirring to 14/20 flasks of 25 mL and up, so you can agitate small batches without oversized hardware. It is a practical choice for method development, small-batch synthesis and teaching labs that rely on overhead motors rather than magnetic stirring.
This listing is for Kimble catalog number 303860-0000: 6mm Precision Stirrer Assembly. The assembly pairs a 6 mm button shaft with a double-curvature PTFE blade. Glass parts are made from low-extractable 33 expansion borosilicate glass meeting USP Type I and ASTM E438, Type I, Class A requirements. The shaft and blade are dimensioned to fit Standard Taper 14/20 necks for use with an overhead stirrer motor. Replacement bearings, shafts and blades are available separately. Order it from LIGHT LABS and keep your lab stocked with genuine DWK Life Sciences products.
