High-quality PTFE (Teflon) Evaporating Dishes. Perfect as a non-stick watch glass cover, for sample evaporation, digestion, and preparation in laboratories. Chemically inert and reusable.

Crafted from premium PTFE, a high-performance fluoropolymer also known as Teflon, this PTFE evaporating dish is an indispensable tool for the modern laboratory. Its defining characteristic is a perfectly non-stick and completely inert surface, which guarantees zero contamination of sensitive samples. This exceptional chemically resistant property allows it to withstand the most aggressive acids, bases, and solvents with ease, making it ideal for demanding procedures like sample digestion for digestion and precise sample preparation.

The dish excels in high temperature applications, maintaining its integrity where other materials would fail. Its robust construction ensures it is a Reusable PTFE workhorse, offering outstanding long-term value and reducing waste. While primarily an evaporating dish, it also functions superbly as a protective watch glass cover for beakers. This versatility is crucial for applications for HPLC and other analytical techniques, where purity and reliability are non-negotiable. For evaporation, covering, drying, or high-temperature digestion, this PTFE dish delivers unmatched performance and durability.

Excellent Chemical & Physical Properties:
Extremely strong chemical inertness (the core advantage)
PTFE is known as the “plastic king” and hardly reacts with any known strong acids, bases, oxidants, organic solvents, etc.
Tolerant reagents include aqua regia, hydrofluoric acid (HF), hot concentrated sulfuric acid, nitric acid, hydrochloric acid, chromic acid, various organic solvents (such as acetone, benzene, alcohols), etc.
This feature ensures that the stored samples are not contaminated by the container and also guarantees that the container itself is not corroded.
Extremely low leaching and adsorption of metal ions
The surface of PTFE is smooth and dense, and it hardly adsorbs trace elements and components in the sample.
The content of self dissolved metal ions is extremely low, which is crucial for trace analysis (such as ICP-MS, ICP-OES, AA, etc.), effectively avoiding background contamination and ensuring the accuracy of analysis results.
Excellent thermal stability
It can usually be used for a long time within the temperature range of -200 ° C to+260 ° C.
Short term tolerance to higher temperatures (such as 300 ° C) makes it suitable for hydrothermal reactions, high-temperature digestion, or high-temperature sample storage.
Excellent non stickiness and surface smoothness
The surface friction coefficient is extremely low, does not adhere to any substances, is easy to clean and pour out viscous reagents, and there will be no residue.
High purity and good electrical insulation
