High Purity PFA Sample Vials Acid Resistant Trace Analysis Digestion Cups with Lids

Product Overview

This high-performance sample preparation system is engineered for laboratories requiring the highest levels of chemical purity and resistance. Fabricated from premium perfluoroalkoxy (PFA), the equipment serves as a critical component in ultra-trace element analysis, providing a nearly inert environment for the digestion and storage of volatile or corrosive samples. Its unique molecular structure ensures that even when exposed to the most aggressive reagents, the integrity of the sample remains uncompromised by leachable contaminants or surface adsorption.

The system is primarily utilized in sectors where baseline stability is non-negotiable, including semiconductor processing, geochemical research, and pharmaceutical trace analysis. By utilizing a fully fluorinated carbon backbone, these units eliminate reactive sites, making them the preferred choice for ICP-MS and LC-MS/MS workflows. Whether used for boiling acid digestions or long-term high-purity solvent storage, the unit provides a reliable barrier against metal ion migration and organic solvent penetration.

Confidence in this equipment stems from its precision manufacturing and material excellence. Designed to withstand extreme thermal fluctuations and prolonged exposure to concentrated nitric, hydrochloric, and hydrofluoric acids, this unit maintains its structural and chemical integrity where traditional labware fails. The robust construction and airtight sealing mechanisms provide peace of mind for researchers handling expensive or irreplaceable samples under demanding industrial conditions.

Key Features

• Extreme Chemical Inertness: The equipment is crafted from high-molecular-weight PFA, which is virtually unreactive to almost all industrial chemicals, including concentrated hydrofluoric acid and aqua regia, ensuring no vessel-to-sample cross-contamination.
• Ultra-Low Metal Ion Background: With a surface that exhibits extremely low metal ion leaching, this system is optimized for ultra-trace analysis where maintaining a low detection limit is critical for data reproducibility.
• Superior Thermal Stability: This unit maintains its mechanical strength and chemical resistance across a broad temperature spectrum, typically ranging from cryogenic levels up to 260°C, allowing for high-temperature digestions without vessel deformation.
• Non-Wetting Surface Properties: The low surface energy of the fluoropolymer material prevents sample droplets from adhering to the internal walls, ensuring maximum sample recovery and facilitating effortless cleaning protocols.
• Advanced Sealing Technology: Each unit features a precision-threaded lid designed to create a liquid-tight and vapor-tight seal, preventing the loss of volatile analytes and protecting the sample from atmospheric contamination.
• Optical Clarity for Process Monitoring: The translucent nature of the material allows laboratory personnel to observe sample reactions, color changes, or the formation of precipitates without opening the vessel and risking contamination.
• High-Purity Manufacturing: Produced in a controlled environment with strict adherence to purity standards, the equipment arrives with a clean baseline, reducing the time required for pre-cleaning in the lab.
• Mechanical Durability: Unlike quartz or glass alternatives, this system is impact-resistant and shatterproof, providing a safer working environment in high-pressure or high-volume industrial settings.
• CNC Precision Customization: Each unit can be tailored through advanced CNC machining to meet specific volumetric or dimensional requirements, ensuring a perfect fit for specialized automated sample changers or heating blocks.
