PTFE Paddle-type Stirrer

About PTFE Paddle-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.

Premium Material and Construction

Manufactured from PTFE combined with 304 stainless steel, this paddle-type stirrer demonstrates superior mechanical strength, a density of 2.2 g/cm3, and a melting point of 327C. Its non-reactive surface resists harsh chemicals, ensuring reliability even in aggressive laboratory conditions.


Versatile Applications

Ideal for chemical laboratories, pharmaceutical industries, and research centers, the stirrer is suited for mixing, agitation, and handling of sensitive or corrosive materials. Thanks to its non-stick, smooth surface, it guarantees consistent results and simplifies cleaning between batches.


Hygiene and Sterilization Advantages

Easily sterilizable by autoclaving or chemical means, the PTFE paddle-type stirrer minimizes contamination risks. Its high reusability, enabled by excellent chemical and corrosion resistance, makes it a cost-effective and environmentally responsible choice.
