Custom PTFE Petri Dish 200mm High Purity Corrosion Resistant Low Background Laboratory Ware

Product Overview

This high-purity laboratory vessel is engineered for the most demanding analytical environments, where sample integrity and chemical inertness are non-negotiable. Crafted from premium virgin Polytetrafluoroethylene (PTFE), this unit provides an unparalleled solution for researchers and industrial technicians who require a 200mm diameter format with absolute resistance to corrosive reagents. The primary value proposition of this system lies in its "low background" profile, ensuring that even at trace levels of analysis, there is no risk of dissolution or precipitation of impurities into the sample.

Designed for use across the semiconductor, pharmaceutical, and geochemical sectors, the equipment excels in processes involving concentrated acids, organic solvents, and high-temperature reactions. Unlike standard glass or plastic labware, this system maintains its structural and chemical integrity under extreme conditions, including exposure to hydrofluoric acid and aqua regia. Its smooth, non-stick surface is particularly valued for the preparation and recovery of delicate materials, ensuring that residues do not adhere to the vessel walls.

Industrial procurement teams can rely on the robustness and longevity of this unit. Every component is manufactured to strict tolerances using advanced CNC machining processes, providing a level of precision that molded alternatives cannot match. This commitment to engineering excellence ensures that the equipment performs consistently over hundreds of cycles, offering a high return on investment through durability and the elimination of sample contamination risks. Whether used for simple evaporative drying or complex membrane casting, this unit represents the pinnacle of fluoropolymer laboratory technology.

Key Features

• Exceptional Chemical Inertness: This system is virtually impervious to all known chemicals, including strong acids, alkalis, and oxidizing agents, making it the ideal choice for trace metal analysis and aggressive digestion processes.
• Ultra-Low Surface Energy: The non-stick properties of the material ensure that samples can be recovered in their entirety without loss to the vessel surface, a critical factor in high-cost pharmaceutical and forensic applications.
• Superior Thermal Stability: Operating efficiently across a broad temperature range from -200°C to +260°C, the equipment maintains its mechanical properties without becoming brittle in cryogenic environments or deforming under high heat.
• Zero Leaching Architecture: Engineered to prevent the dissolution and precipitation of metal ions or organic contaminants, this unit ensures a "clean" background for ICP-MS and other sensitive analytical techniques.
• High-Precision CNC Fabrication: Unlike mass-produced labware, this unit is machined from solid blocks of high-density PTFE, resulting in superior dimensional stability, thicker walls, and a more robust construction.
• Hydrophobic Surface Performance: The water-repellent nature of the equipment prevents aqueous solutions from wetting the surface, facilitating easier cleaning and cross-contamination prevention between experimental runs.
• Dielectric Reliability: With a constant dielectric value of 2.1, the material provides excellent electrical insulation, making it suitable for specialized electrochemical research and sensitive electronic component testing.
• Custom Engineering Flexibility: While the standard diameter is 200mm, the system is fully customizable in terms of wall thickness, depth, and lid configurations to meet specific laboratory protocols.
