Compared to using improvised sieving methods in the past, the VWR Testing Sieves, All Brass 45BB8H Half Height have significantly improved the accuracy and efficiency of my soil analysis work.

Breaking Down the Features of VWR Testing Sieves, All Brass 45BB8H Half Height

Specifications

• Diameter: 20.3 cm (8″): The industry-standard size makes it compatible with most sieve shakers and testing setups. This allows for consistency across different labs or testing environments.
• Height: Half Height (2.54cm (1″) depth above wire): This design optimizes handling and reduces material spillage, especially useful when working with fine powders. This smaller size makes the sieves easier to stack and store.
• Frame Material: Brass: Brass provides excellent durability and resistance to corrosion, ensuring a long lifespan even with frequent use. The brass frame is also non-reactive, preventing contamination of samples.
• Wire Cloth Material: Brass: Similar to the frame, brass wire cloth offers durability and prevents sample contamination. The brass also resists wear and tear.
• USA Series: #45: This refers to the mesh size in the USA standard. A #45 sieve has 45 openings per linear inch.
• Sieve Opening: 355 µm (0.0140″): Determines the size of particles that will pass through the sieve. This specification is crucial for precise particle size analysis.
• Compliance: ASTM E-11 and ISO specifications: Ensures that the sieve meets recognized industry standards for accuracy and quality. Adherence to these standards is essential for reliable and reproducible testing results.
• Fillet Solder Bead: Prevents particles from being trapped between the mesh and the frame, maintaining sample integrity. The bead simplifies cleaning, reducing the risk of cross-contamination.
• Serial Number and Certificate of Compliance: Provides traceability and assurance of quality control. It enables easy tracking of the sieve’s performance and adherence to specifications.
