Custom 100ml PTFE Digestion Tube for Heavy Metal Trace Analysis and High Temperature Acid Digestion

Product Overview

This high-performance digestion vessel is engineered specifically for the most demanding analytical laboratory environments, where chemical purity and material integrity are non-negotiable. Crafted from premium-grade Polytetrafluoroethylene (PTFE), the unit provides an inert environment essential for heavy metal trace analysis and microwave digestion processes. By utilizing advanced fluoropolymer technology, the equipment ensures that sample integrity is maintained even when exposed to the most aggressive reagents, such as concentrated nitric, hydrochloric, or hydrofluoric acids. The primary value proposition lies in its ability to eliminate cross-contamination and sample loss through a combination of superior material selection and precision manufacturing.

Designed for versatility, this system is a staple in environmental testing, food safety labs, and metallurgical research. It excels in applications involving acid driving (evaporation) and digestion, where consistent thermal stability and chemical resistance are paramount. The unit’s robust construction allows it to withstand the high-temperature and high-pressure conditions typically found in modern digestion protocols. By providing a stable, non-reactive platform for sample preparation, the equipment empowers researchers to achieve higher detection limits and more reproducible results in arsenic analysis and other sensitive elemental determinations.

Built with a focus on reliability and longevity, this unit represents a critical investment in laboratory infrastructure. Every vessel is manufactured through high-precision CNC processes to ensure uniform wall thickness and a flawlessly smooth internal surface finish. This meticulous attention to detail minimizes the risk of structural failure under thermal stress and ensures that the equipment can be reused across thousands of cycles without degrading. Procurement teams and laboratory managers can rely on this unit to maintain its performance specifications over time, reducing the total cost of ownership while maximizing the accuracy of analytical outputs in heavy-use industrial settings.

Key Features

• Superior Chemical Inertness: The equipment is manufactured from high-purity PTFE, providing absolute resistance to almost all laboratory chemicals, including aqua regia and hydrofluoric acid, ensuring the vessel never reacts with the sample.
• Precision-Machined Internal Surface: The smooth, non-stick inner wall is achieved through specialized CNC finishing, which prevents the adsorption of trace elements and ensures 100% sample recovery during the transfer and acid driving stages.
• Exceptional Thermal Stability: This unit is capable of continuous operation at temperatures up to 260°C, maintaining its structural integrity and sealing capabilities during high-temperature digestion and evaporation procedures.
• Minimal Trace Element Leaching: Engineered specifically for heavy metal analysis, the material grade used in this system has extremely low background levels of target analytes like arsenic, lead, and cadmium, preventing sample contamination.
• High Pressure Tolerance: Designed with a focus on safety and performance, the equipment features a robust wall thickness that allows for safe operation during pressurized microwave or block digestion workflows.
• Optimized Acid Driving Geometry: The internal geometry is specifically contoured to facilitate efficient evaporation and acid driving, reducing processing time and ensuring uniform concentration of the analyte.
• Customizable Dimensional Profiles: This equipment can be tailored to meet specific laboratory requirements, including custom heights, diameters, and closure types, ensuring compatibility with any existing heating block or microwave system.
• Enhanced Durability: Unlike glass or inferior polymers, this unit will not chip, crack, or shatter, providing a safer working environment and long-term reliability in high-throughput industrial laboratories.
• Non-Adhesive Properties: The hydrophobic nature of the material prevents the buildup of residues, making the cleaning process significantly faster and more effective, which in turn reduces the risk of carry-over between samples.
