The LARK LMS-A0825 PTFE Magnetic Stirring Bar with Centre Ring is a chemically resistant laboratory stirring bar designed for use with magnetic stirrers and hotplate stirrers. Its 8 × 25 mm PTFE construction and central pivot ring provide efficient spinning, including in vessels with curved or uneven bases.

Product Overview

The LARK LMS-A0825 is a PTFE/Teflon magnetic stirring bar designed for reliable liquid mixing in laboratory applications.

The central pivot ring helps the bar spin efficiently in a wide range of containers and is particularly useful where the vessel has a curved or uneven base. The magnetic core consists of a strong alloy magnet enclosed within white inert PTFE.

PTFE provides high resistance to chemical attack and is suitable for a broad range of laboratory stirring applications.

The LMS-A0825 has an 8 × 25 mm size and is supplied in a standard pack of 10 pieces.
