Rp123.00
Our PTFE neck flask is a highly specialized laboratory reaction vessel made from Polytetrafluoroethylene, chosen for its exceptional chemical inertness and ability to operate across a wide temperature range. They are a safe, non-contaminating alternative to traditional glass flasks when working with highly corrosive or sensitive substances.
Key Features:
Material: Made from pure, virgin PTFE, offering the highest level of chemical resistance against virtually all acids, bases, and organic solvents.
Temperature Range: Designed to withstand extreme temperatures, typically from -200°C to +250°C, without degradation or distortion.
Neck Configuration: Available with single, two, three, or four necks, featuring standard tapered joints (e.g., 24/40, 19/22) for compatibility with other lab equipment like condensers or stirrers.
Design: Often features a threaded connection between the flask body and the neck/cover for easy disassembly and thorough cleaning.
Purity: The non-stick, super-smooth internal finish minimizes sample adhesion and the risk of metal ion leaching, which is critical for trace analysis.
Primary Applications:
Hydrofluoric Acid (HF) Use: The primary container for any reactions or storage involving hydrofluoric acid, as HF attacks and dissolves glass.
Trace Metal Analysis (ICP-MS): Sample preparation where preventing metal ion leaching from glassware is crucial for accurate results.
High-Purity Organic Synthesis: Used in complex reactions to prevent contamination and maintain inert atmospheres using sealed neck connections.
Microwave Digestion: Specialized PTFE vessels can be used within microwave systems for rapid, high-temperature sample digestion due to PTFE's transparency to microwaves.
