Custom PTFE Petri Dish 120mm Diameter Corrosion Resistant Low Background High Purity Labware

Product Overview

This high-purity laboratory vessel is engineered for the most demanding analytical environments, where chemical inertness and material integrity are non-negotiable. Crafted from premium polytetrafluoroethylene (PTFE), this system provides an uncompromising solution for researchers and industrial technicians who require a 120mm diameter footprint without the risk of sample contamination. Unlike traditional borosilicate glass or commodity plastics, this unit is designed to withstand aggressive reagents, including hydrofluoric acid and strong alkalis, while maintaining a stable, non-reactive surface. Its core value proposition lies in its ability to facilitate ultra-trace analysis by eliminating the leaching of ions and organic compounds that typically interfere with sensitive measurements.

The equipment is primarily utilized in sectors such as environmental monitoring, semiconductor fabrication, pharmaceutical research, and geological isotopic analysis. By providing a low-background environment, it enables the precise quantification of elements at the parts-per-billion (ppb) or parts-per-trillion (ppt) level. Whether used for sample evaporation, crystallization, or specialized microbial culturing in harsh chemical media, the unit performs with exceptional consistency. Its robust construction makes it a staple in laboratories focusing on high-purity chemical processing and specialized sample preparation workflows.

Confidence in this system stems from the inherent properties of the high-grade fluoropolymer used in its construction. With a melting point of 327°C and significant thermal stability, the equipment remains reliable under fluctuating temperature conditions. The precision-machined finish ensures a crevice-free internal geometry, which is critical for both the prevention of sample entrapment and the ease of rigorous cleaning protocols. For industrial buyers, this represents a long-term investment in operational reliability, as the unit is virtually immune to the cracking, etching, or degradation associated with lower-grade materials in corrosive environments.

Key Features

• Exceptional Chemical Inertness: This system is virtually non-reactive to almost all industrial chemicals, including concentrated acids, bases, and organic solvents, ensuring no degradation during long-term exposure.
• Ultra-Low Background Levels: Specifically engineered for trace analysis, the material minimizes the presence of extractables, providing a clean baseline for ICP-MS and other high-sensitivity analytical techniques.
• High-Temperature Stability: With a functional range extending up to 260°C and a melting point of 327°C, the unit maintains its structural integrity and chemical resistance even during high-heat digestion processes.
• Hydrophobic Surface Finish: The naturally low surface energy of the material prevents aqueous solutions from wetting the surface, facilitating complete sample recovery and simplifying post-process decontamination.
• Zero Leaching and Dissolution: The molecular structure of the equipment ensures that no plasticizers, catalysts, or impurities migrate into the sample, preserving the purity of delicate reagents.
• Customizable Geometry: Beyond the standard 120mm diameter, this unit can be tailored through precision CNC machining to meet specific depth, wall thickness, or specialized lid requirements for unique laboratory setups.
• High Impact Resistance: Unlike brittle glass alternatives, this fluoropolymer system is remarkably durable and resistant to mechanical shock, reducing the risk of hazardous chemical spills in the workspace.
• Non-Stick Internal Surface: The smooth, crevice-free internal finish prevents the adhesion of precipitates or biological cultures, ensuring consistent results across multiple cycles.
