PTFE Frame Stirrer

About PTFE Frame 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.

Durable Construction for Demanding Environments

This PTFE Frame Stirrer is manufactured using high-grade PTFE encapsulating a 304 stainless steel core, resulting in exceptional durability and chemical resistance. Its design effectively withstands the rigors of strong acids, bases, and solvents, making it indispensable in labs working with aggressive substances.


Optimal Stirring Performance

With a maximum speed of up to 1200 RPM and sizes ranging from 200 mm to 600 mm in length, the frame stirrer delivers uniform mixing for a wide array of applications. Its smooth, non-stick finish ensures effortless cleaning and prevents contamination between batches for reliable and repeatable results.


Safety and Compliance Assured

This stirrer meets FDA approval standards, providing confidence for users in critical chemical and pharmaceutical processes. The material's resistance to wear and thermal degradation ensures long service life, while sterilization via chemical or steam methods maintains operational sterility for sensitive applications.
