Labtek Enterprises manufactures and supplies laboratory Test Sieves for accurate particle size analysis, material grading and quality-control applications. Test Sieves are commonly used in aggregate, soil, cement, construction-material, powder and general laboratory testing.
The correct sieve should be selected according to the required aperture opening, frame diameter, sieve material and applicable test method. For mechanical sieve analysis, laboratories can use compatible Test Sieves with our Sieve Shaker for particle size analysis.
Test Sieves may be selected with reference to standards such as ASTM E11 and ISO 3310, depending on the laboratory procedure and customer requirement. These standards are commonly associated with specified sieve openings and woven-wire test sieves used for particle-size analysis.
Brass Test Sieves are widely used for routine laboratory applications, while stainless-steel Test Sieves may be preferred where durability, corrosion resistance or specific laboratory conditions are important.
For a commonly used laboratory configuration, see our 8 Inch Brass Test Sieve.
Test sieve sizes are often described using a sieve number, aperture opening in millimetres or a micron value. The actual aperture opening should be used as the primary reference when selecting a sieve for a defined laboratory test method.
| Sieve No. | Opening | Micron |
|---|---|---|
| No. 4 | 4.75 mm | 4750 µm |
| No. 8 | 2.36 mm | 2360 µm |
| No. 20 | 850 µm | 850 µm |
| No. 40 | 425 µm | 425 µm |
| No. 100 | 150 µm | 150 µm |
| No. 200 | 75 µm | 75 µm |
Note: Mesh-number terminology can vary between sieve standards, so the required aperture and applicable test procedure should be confirmed before ordering.
For sieve analysis, multiple Test Sieves with progressively smaller openings can be stacked to determine particle-size distribution. If you need help selecting a mesh, micron size, aperture, sieve material or testing standard, contact Labtek Enterprises.
Quick guidance on mesh size, micron openings, standards, materials and sieve selection for laboratory particle size analysis.
A Test Sieve is a laboratory screening instrument with a controlled opening size used to separate and classify particles according to size. Test Sieves are commonly used for particle size analysis, material grading and quality-control testing.
Mesh refers to the number of openings across a defined length of sieve mesh, while micron describes the approximate size of the opening in micrometres. For precise selection, the actual aperture or opening size should be checked against the required test method or standard.
ASTM E11 and ISO 3310 are widely used standards covering requirements for test sieves and sieve cloth. The suitable standard depends on the test procedure, laboratory specification and applicable industry requirement.
Both materials are used for laboratory sieving. Stainless steel is commonly selected where corrosion resistance and durability are important, while brass frames may be suitable for general laboratory applications. Selection should also consider the test method, sample material and operating environment.
Start with the required aperture, mesh or micron size, followed by the applicable testing standard, sieve diameter, frame material and sample type. If the specification is unclear, our team can assist with technical sieve selection.

A sieve shaker helps provide repeatable mechanical agitation when multiple sieves are stacked for particle size analysis. It is useful where consistent sieving motion, test repeatability and efficient sample separation are required.
