This PTFE sieve, also known as a Teflon sieve, is a precision filtration and grading device based on high-purity PTFE material. Its core structure is a PTFE mesh with a specific pore size, making it an excellent chemical resistant PTFE sieve.

The product has excellent acid proof and non stick properties, which can completely resist the erosion of strong corrosive solvents and ensure that the material has no residue. It is particularly suitable for use as a high standard experimental test sieve and is an ideal choice for high-purity screening and filtration in laboratories, pharmaceuticals, and chemical industries.

(The PTFE sieve meshes in the middle can be stacked in a theoretically unlimited number of layers.)

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
