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.
