PTFE-Coated Stainless Steel Stirrer

This PTFE-coated stainless steel stirrer is built for laboratory mixing tasks. The 5/16 inch shaft diameter and 15-3/4 inch shaft length suit standard overhead stirrer mounts. The 2-11/16 inch blade diameter provides effective agitation. It is designed for use with the 22CZ41 model.

Replaces Worn or Incompatible Shafts

The stirrer replaces damaged shafts or upgrades uncoated steel that risks sample contamination. The jump is worth it when chemical resistance or non-stick performance is required. PTFE coating prevents adhesion and withstands aggressive reagents. It restores reliable stirring without replacing the motor unit.

Handles Viscous Batches With Headroom

The blade diameter comfortably handles medium-volume vessels and moderate viscosities. The coated surface resists buildup during extended runs. It runs out when torque demands exceed the motor coupling or when vessel diameter exceeds the blade sweep. The fixed shaft length limits depth adjustment in tall containers.

Questions about this item

What shaft diameter and length does the 29PD14 stirrer need to fit?

The stirrer has a 5/16 inch shaft diameter and a 15-3/4 inch shaft length, so the chuck or coupling must accept those dimensions.

How is the PTFE coated stirrer installed, and what step is often missed?

Insert the 5/16 inch shaft into the motor chuck, tighten securely, then centre the 2-11/16 inch blade in the vessel; the step often missed is verifying blade clearance before starting.

When will the PTFE coating on this stirrer need replacement?

Replace the stirrer when the PTFE coating shows scratches, flaking or chemical attack that exposes the stainless steel underneath.
