PTFE Rod-type Stirrer

About PTFE Rod-type Stirrer

Product Overview

PTFE Stirring Paddles are essential for achieving homogenous mixing in high-purity chemical reactions and trace analysis preparation. Unlike glass or stainless steel impellers, these paddles provide a non-stick, hydrophobic surface that resists fouling and prevents contamination from silica or metallic ions. Whether used for simple liquid blending or high-viscosity dispersion, our paddles ensure that your reaction remains pure and your equipment remains protected from the most aggressive chemical environments.

Comprehensive Impeller Types

We offer a wide array of specialized geometries to match your specific fluid dynamics requirements, all of which can be customized:

• Crescent (Half-Moon): Designed to fit through narrow flask necks and expand during rotation for efficient mixing.

• Cross-Blade: Ideal for general-purpose turbulence and radial flow in standard beakers.

• Paddle (Blade) Type: Provides high-flow circulation for low-viscosity liquid-liquid blending.

• Anchor Type: Perfect for high-viscosity materials, ensuring consistent movement along the vessel walls.

• Frame Type: Used for heavy-duty mixing and preventing sedimentation in large-volume reactors.

• Toothed Disc Turbine: Engineered for high-shear applications and the dispersion of fine powders into liquids.

• Straight Rod (Stirring Bar): A simple, effective solution for micro-scale stirring and delicate sample handling.

Product Synergy & Workflow

• PTFE Flasks & Reactors: The primary vessels where these paddles provide the mechanical energy for synthesis and dissolution.

• PTFE Constant-Pressure Dropping Funnels: Complements the paddle by ensuring immediate mixing as reagents are added drop-wise.

• PFA/PTFE Condensers: Used in reflux setups where constant stirring is required to maintain temperature uniformity.

Application Fields & Industries

• Trace Element Analysis: Homogenizing samples in ultra-pure acid environments for ICP-MS prep.

• Fine Chemical Synthesis: Handling of catalysts and reactive precursors in pharmaceutical and polymer research.

• Semiconductor Industry: Mixing of high-purity etching solutions and chemical mechanical polishing (CMP) slurries.

• Material Science: Dispersion of nanomaterials and high-purity ceramics in aggressive solvent matrices.

Ultimate Chemical Resistance and Safety

Manufactured from high-grade PTFE, our rod-type stirrers are completely non-reactive and corrosion-resistant, enabling safe handling of aggressive chemicals. Their inertness to acids, bases, and solvents ensures your formulations remain uncontaminated, making them ideal for laboratory, pharmaceutical, and food industry environments.


Customizable for Diverse Applications

Available in various standard and custom sizes, PTFE rod stirrers can be tailored for specific laboratory equipment or food/pharmaceutical mixing processes. Length, width, and thickness options meet a wide array of stirring requirements, providing flexible solutions for exporters, manufacturers, and suppliers alike.


Superior Non-stick and Electrical Properties

With an ultra-smooth, non-stick surface, our PTFE stirrers prevent material buildup during mixing. Their outstanding dielectric properties provide excellent electrical insulation, adding another layer of safety in laboratory and industrial environments.
