PTFE Stirrer Bearing Adapter MECCANIXITY 21.5mm-25mm 8mm Shaft 2pcs

Description

Product Overview

The MECCANIXITY PTFE Lab Stirrer Bearing Adapter is engineered to provide a reliable interface between electric stirring rods and laboratory glassware. Constructed from high‑purity PTFE, the adapter offers exceptional chemical resistance and a broad temperature tolerance ranging from –180 °C to 250 °C, making it suitable for a wide variety of experimental conditions. Its dimensions—top diameter 25 mm, bottom diameter 21.5 mm, total height 47 mm, and an 8 mm central bore—ensure a snug fit on standard 8 mm diameter stirring shafts while expanding the mounting aperture to accommodate larger stirrers. The package includes two identical adapters, each equipped with a sealing O‑ring that delivers a tight, leak‑free seal when installed.

Usage

Designed for use in chemistry, biology, and materials research laboratories, this bearing adapter excels in applications where precise mixing and temperature control are critical. It can be employed in beakers, flasks, and reaction vessels to securely hold double‑paddle PTFE stirring rods during prolonged heating, cooling, or reflux operations. The adapter’s PTFE surface minimizes friction, allowing the stirrer to rotate smoothly even at high speeds, which reduces wear on both the rod and the glassware. Researchers working with corrosive solvents, aggressive acids, or volatile organic compounds will appreciate the adapter’s inertness, which prevents contamination of the sample and prolongs the lifespan of the equipment.

FAQ

What materials can I safely use with this PTFE adapter?

The adapter is compatible with most laboratory chemicals, including strong acids, bases, solvents, and organic reagents, because PTFE is chemically inert.

Can the adapter withstand high‑speed stirring?

Yes. PTFE’s low friction surface allows smooth rotation at high speeds without generating excessive heat or wear on the stirrer shaft.

Is the O‑ring replaceable?

Absolutely. The O‑ring is a standard size that can be swapped out if it becomes worn or damaged, ensuring continued sealing performance.

What is the recommended cleaning procedure?

Rinse the adapter with deionized water after use, then soak in a mild PTFE‑compatible solvent if needed. Dry thoroughly before storage.
