PTFE Serrated Stirring Blade 100mm Diameter

PTFE Serrated Stirring Blade(also known as a PTFE stirring paddle/disperser) is a laboratory/industrial stirring tool primarily composed of a polytetrafluoroethylene (PTFE) outer casing containing a stainless steel rod and movable PTFE stirring blades.  It features excellent chemical resistance, high-temperature resistance, anti-adhesion properties, and strong stirring power. It is commonly used for mixing corrosive liquids, high-temperature solutions, or high-viscosity media in flasks.

Working principle:

By connecting to a mechanical stirrer, the PTFE stirring blade rotates at high speed inside the flask, generating a vortex that thoroughly mixes and disperses the solution.

Main Features:

Excellent chemical stability: PTFE material (commonly known as "Teflon") is inert to most chemicals and resistant to corrosion.

Wide temperature range: Can withstand temperatures from low temperatures to approximately 260°C, making it ideal for high-temperature reactions.

Low friction and non-stick properties: Smooth surface, easy to clean, and reduces sample adhesion.

Efficient stirring: Designed with movable blades to provide powerful stirring.

Internal stainless steel reinforcement: Ensures structural strength while preventing direct contact between PTFE and the solution (blades only).

Application Field：

Used in chemistry, biochemistry, and pharmaceutical laboratories for stirring various acids, bases, solvents, and organic compounds.

Suitable for high-temperature reactions and mixing processes involving corrosive media.
