Stirring Shaft, 19mm, Complete

Eliminates Flask Breakage:

• PTFE is the only contact in the lower radius of the flask, therefore breakage due to dropping the stirrer shaft has been eliminated.
  Eliminates the Frustration of Assembly:
• Unique design permits the proper amount of tension to be applied to the blade, thereby preventing the blade from flipping over to the incorrect side during insertion into the flask.
• Special PTFE blades are not required. Design permits use with any PTFE stirrer blade with the keyhole shaped cutout for 10mm or 19mm shafts.
• Available in both Ground and Polished styles.

A 19mm OD precision ground stirrer shaft with our patented** Chem-Stir™ blade attachment system. Shaft (C) has been manufactured with a ring at the lower end to permit attachment of the blade (B) with a PTFE nut (D) and bolt (A). Shaft is supplied complete with PTFE nut and bolt set. The top end of the stirrer shaft is reduced to 1/2" (12.7mm) to fit into a CG-2046-03 universal adapter while the unground length varies to accommodate different flask capacities. PLEASE NOTE: STIRRER BLADES MUST BE PURCHASED SEPARATELY.

THESE SHAFTS ARE NOT TO BE USED WITH ANY TYPE OF PTFE BEARING. FOR POLISHED SHAFTS USED WITH PTFE BEARINGS SEE CG-2087.

PLEASE NOTE: 19MM SHAFTS HAVE A REDUCED DIAMETER TOP SECTION THAT IS 1/2"OD, PLEASE KEEP THIS IN MIND WHEN SELECTING THE PROPER SIZE COUPLING.
