LABALPHA 800 Mesh Lab Sieve 8in Diameter - Precise 0.02mm Filtration

In this review the LABALPHA 800 Mesh Lab Sieve is evaluated for lab users and small-scale milling operations that need fine, repeatable filtration. The biggest reason to consider this sieve is its uniform 0.02mm aperture, which delivers consistent particle separation across batches. Built with a double-layer frame and 304 stainless steel wire cloth, this sieve suits users who require corrosion resistance and easy cleaning while processing powders, soils, metal powders or grains.

Key Features

• 800 mesh, 0.02mm aperture: Offers very fine screening suitable for powders and very small particulates, improving consistency in sample preparation.
• 8in diameter size: The 20cm diameter provides a practical working area for laboratory sieving and small production runs without being cumbersome.
• 304 stainless steel construction: The stainless mesh and double-layer frame resist corrosion and tolerate a wide temperature range for lab use.
• Well-manufactured mesh: Standardized screen mesh with uniform apertures ensures predictable separation and repeatable results.
• Easy to maintain: Smooth edges and stainless surface make the sieve simple to rinse and clean between uses, reducing cross-contamination risk.

Who It's For

This sieve is aimed at laboratory technicians, hobby chemists, small milling operations and geotechnical teams that need a compact, reliable tool for very fine particle separation. It works well for straining powders, aluminum or zinc dusts, sand and soil samples, and can be used in setups that require filtering of organic liquids when a fine mesh is appropriate.

Those who need very high throughput industrial screening or very large sample volumes should look elsewhere for larger diameter or stackable industrial sieves. Also, if your work demands multiple mesh sizes simultaneously, consider purchasing a set rather than a single 800 mesh unit.

Pros & Cons

Pros

• Corrosion-resistant 304 stainless steel gives long service life in lab environments.
• Uniform standard 800 mesh pattern delivers consistent milling and sieving performance reported by users.
• Compact 8in diameter balances usable area and portability for bench-top use.
• Double-layer frame improves durability without adding much weight.

Cons

• Single mesh size means additional sieves are required for particle size ranges outside 0.02mm.
• Not designed for high-volume industrial throughput where larger machines are preferable.

Our Verdict

The LABALPHA 800 Mesh Lab Sieve is a solid choice for lab users and small mills who need precise, repeatable fine filtration in a compact package. Its 304 stainless steel construction, uniform 0.02mm aperture and manageable 8in size make it good value for anyone prioritizing durability and consistent sieving over high-volume throughput.

Frequently Asked Questions

Is this sieve suitable for wet filtration?
Yes, the 304 stainless steel and smooth edges tolerate occasional wet use, though rinsing and drying after use is recommended to prevent residue build up.

Can this replace larger industrial sieves?
Not for high-volume industrial work; it is best suited to lab batches, sample prep and small-scale milling where an 8in sieve is sufficient.

How precise is the mesh opening?
The sieve uses a standard 800 mesh with an approximate 0.02mm aperture, providing uniform and predictable particle separation.
