QLA Paddles

QLA offers electropolished 316 stainless steel paddles and a proprietary flouropolymer paddle (Patent Pending). The flouropolymer paddles provide a seamless construction eliminating corrosion and contamination encountered with conventional three-piece assemblies. Both styles comply with USP (711) and original equipment manufacturers dimensional specifications. All QLA paddles are precisely manufactured to limit rotational wobble to levels far below USP (711) specifications.

Types of Paddles

Electropolished 316 Stainless Steel - The 316 stainless steel (316 SS) shaft is strong and has a high resistance to bending. It is electropolished for removal of surface impurities and corrosion resistance.

PTFE Coated - The USP suggests that paddles may be coated with an inert coating. Most paddles are accordingly coated with PTFE or another inert coating. If peeling or flaking of the coating is observed then the paddles should be replaced.

Solid Fluoropolymer - The single piece molded design features a fluoropolymer blade and single piece stem molded onto an electropolished 316 SS shaft. This innovative design features no paddle-to-shaft joint, thus eliminating potential cross-contamination and removing a probable corrosion path. Wobble is also considerably reduced in the solid fluoropolymer paddle because it is a single piece cast.

Care & Maintenance

Shaft Storage - Bent or scratched shafts fail to comply with USP regulations so it is essential not to store shafts on a desk or loose in a drawer where damage or corrosion can occur. Proper storage in a basket shaft/paddle holder can prevent damage from occurring.

Wobble - A Wobble Meter (WOBMET-MI) is available to monitor paddle wobble.
