Stainless Steel Laboratory Test Sieves

In particle size analysis, technicians often encounter problems such as fine powder clogging the mesh or data distortion caused by mesh displacement during vibration. Ordinary industrial sieves have large tolerances, easily missing particles exceeding the standard. Stainless Steel Laboratory Test Sieves, however, offer non-deformable standardized meshes, manufactured strictly according to standards, with sieve openings covering 20 to 125 micrometers, solving the problem of separation consistency and accurately measuring the true distribution of particles of various sizes.

The SUS304 and SUS316 stainless steel materials are rust-resistant and acid and alkali-resistant, avoiding the drawbacks of traditional brass sieves such as oxidation, deterioration, and residual metal impurities. Their inert structure prevents chemical contamination of samples during testing.

What are the benefits of using Stainless Steel Laboratory Test Sieves?

Using laboratory-grade stainless steel standard sieves provides long-term durability and reliable repeatable testing. Seamless laser welding eliminates gaps at the connection between the sieve mesh and frame, preventing particle retention, simplifying the cleaning process, and avoiding cross-contamination between different batches of samples. The mesh is mechanically stretched before fixing, ensuring uniform tension and preventing sagging even under continuous heavy loads from the vibrating screen. It maintains stable aperture dimensions even after years of use. The tightly nested design ensures a seamless fit between the top and bottom edges of the screen frame, allowing multiple screens to be stacked securely without wobbling, preventing dust leakage into the air.

Stainless Steel Laboratory Standard Sieve Specifications

Stainless steel laboratory test sieves strictly comply with ISO 3310-1 (International Standard) and ASTM E11 (American Standard).

How much do stainless steel laboratory test sieves cost?

The price of a single stainless steel laboratory standard sieve typically ranges from $35 to $280. ​​As it is a metrological tool, the price depends on the specific configuration and is not fixed. Two variables influence cost: first, the mesh size. Coarse screens (2mm to 10mm) are simple to manufacture and cost between $35 and $60, while ultrafine screens (below 45 microns) require special micro-wire weaving and cost over $150. Second, the screen frame diameter. Standard 200mm frames are cheaper to produce in bulk, while larger 300mm or 400mm frames require more raw materials and custom packaging, thus increasing the price.

Stainless Steel Laboratory Test Sieves Application Scenarios

Particle testing requires analyzing the physical properties of materials from different industries. Applications include: in powder metallurgy and 3D printing, technicians use 45-micron and 63-micron sieves to separate spherical titanium powder from stainless steel particles, preventing excessively large particles from clogging nozzles; in civil engineering, geotechnical laboratories stack coarse sieves to classify quartz sand, crushed granite, and concrete aggregates to calculate the load-bearing capacity of the mixture; in the flour milling industry, millers use them to sieve wheat bran and rye flour to monitor starch damage and ash content, as regulations prevent the use of brass sieves; in battery manufacturing, production lines use them to inspect synthetic graphite and lithium iron phosphate powder, controlling narrow particle distribution to improve battery energy density.

Frequently Asked Questions

Q: What is a stainless steel sieve used for?

A: It serves as a physical reference standard, separating bulk particle samples into different size fractions. By stacking multiple standard sieves on a sieving machine, laboratory operators can measure the percentage of material weight that passes through or remains on each sieve layer.

Q: What is the chemical test for SS 304?

A: Apply a molybdenum element detection solution to the metal surface. If it turns dark red within 30 seconds, it indicates a high manganese content, indicating a lower grade of 201 steel. Genuine SUS304 contains chromium and nickel and resists color change under standard acid point testing.

Q: What is an ASTM 80 sieve?

A: An ASTM E11 standard 80 sieve has a nominal sieve aperture size of 180 micrometers (0.180 mm). The wire diameter is approximately 131 micrometers, leaving approximately 33.6% of the open area for material passage.

Q: How to clean and maintain stainless steel laboratory standard sieves?

A: Do not use a wire brush to prevent pore deformation. Immerse in an ultrasonic bath with a mild detergent for 5-10 minutes, rinse with distilled water, and then dry in an oven below 60°C to prevent thermal expansion from damaging the mesh tension.

Stainless steel laboratory standard sieves are tools for separating particle size distributions in powder production and civil aggregate testing. Their SUS304 or SUS316 construction prevents sample contamination while resisting wear from high-frequency vibrations.
