Product Description
A true-running shaft is what keeps an overhead stirrer quiet, sealed and free of wobble. This precision-ground glass shaft is made for that job, giving your stirrer bearing a smooth, accurate surface to turn against. It is a straightforward replacement when an existing shaft is chipped, bent or no longer seals well in its bearing.
This listing is for Kimble catalog number 304151-0000: 10mm Precision Ground Shaft, 440 mm, 19/22. Each shaft is 10 mm in diameter with a precision-ground surface and is made from low-extractable 33 expansion borosilicate glass meeting USP Type I and ASTM E438, Type I, Class A requirements. Lengths from 440 to 700 mm are offered to suit bearings and flasks with joints from 19/22 up to 55/50. Pair the shaft with a compatible bearing and blade for a complete stirring setup. Order it from LIGHT LABS and keep your lab stocked with genuine DWK Life Sciences products.
