Custom PTFE Electrochemical Sample Clamp for Graphite Sheets and Reticulated Vitreous Carbon

Product Overview

This premium custom sample clamp is engineered to secure thick, rigid, or highly porous sheet materials within electrochemical test cells. Specifically optimized for materials like graphite plates, Reticulated Vitreous Carbon, and metal meshes, this system provides an exceptionally stable mechanical grip and highly reliable electrical connectivity.

Utilizing high-density, virgin polytetrafluoroethylene as the primary structural material, the fixture remains entirely inert across the entire electrochemical window. This ensures that no unwanted background currents or chemical contaminations interfere with sensitive analytical data during battery, electrocatalysis, or corrosion research.

Precision-machined via advanced CNC technology, the equipment delivers unmatched stability and repeatability under aggressive conditions. It resists strong acids, alkalis, and high temperatures, providing ultimate experimental confidence where standard commercial holders fail.

Key Features

• Chemically Inert PTFE Body: Machined from high-purity virgin polytetrafluoroethylene to prevent chemical attack, swelling, or contamination in aggressive electrolytes and solvents.
• Thick Sample Capability: Designed specifically to clamp thick materials like graphite sheets, reticulated vitreous carbon, and metal meshes up to 6.0 mm thick without crushing them.
• Low-Resistance Contacts: Employs an integrated high-purity platinum or gold contact pad to ensure direct electrical connection and minimize IR drop during electrochemical testing.
• Precision CNC Tolerances: Built with high precision to ensure perfect alignment, smooth screw threads, and secure positioning of the electrode sample.
• Capillary Electrolyte Seal: Utilizes a compression collar design that prevents electrolyte from wicking up the support shaft and corroding the outer electrical connection ports.
• Cryogenic to High-Temp Stability: Maintains structural and mechanical integrity in extreme environments ranging from liquid nitrogen temperatures up to 250°C.
• Adaptable Banana Jack Connection: Equipped with a standard 2 mm jack that enables fast, reliable plug-and-play connections to potentiostats and galvanostats.
• Custom Rod Configurations: Supports custom modifications to the rod length, diameter, and jaw shape to fit any custom or commercial cell setup perfectly.

Applications

This specialized sample holder is designed to handle challenging materials that conventional electrochemical clamps cannot support. Below are the key industrial and research applications:

Technical Specifications

Ultra-Pure PTFE for Interference-Free Testing

The PL-DJ45 is manufactured from premium virgin PTFE to avoid trace metal contamination. This ensures that analytical techniques like cyclic voltammetry reflect only the true reactions of the target sample. The material's low surface energy also enables fast, thorough cleaning between test runs.

Low-Resistance Contacts and Stable Electrical Pathways

With a high-purity platinum contact embedded in the clamping jaw, the PL-DJ45 minimizes contact resistance to under 0.1 ohms. This design prevents voltage drops and stabilizes potential control during high-current density operations.

Delicate Clamping for Porous and Brittle Materials

For delicate materials like Reticulated Vitreous Carbon (RVC), the PL-DJ45 features a manual PTFE thread mechanism. This allows precise control over clamping force, preventing structural damage while maintaining excellent electrical contact.

Complete CNC Adaptability for Custom Cells

Through KINTEK's end-to-end CNC custom machining capabilities, the PL-DJ45 can be tailored to fit your exact cell. Adjust the rod length, rod diameter, or jaw aperture to match standard or proprietary laboratory glass cell lids seamlessly.
