Breaking Down the Features of VWR Testing Sieves, 8 Brass Frame, Stainless Steel Wire Cloth 8BS8F Full Height
Specifications
The VWR Testing Sieves, 8 Brass Frame, Stainless Steel Wire Cloth 8BS8F Full Height boasts several critical specifications that ensure accurate and reliable particle size analysis. The 8-inch (20.32cm) diameter provides a standard size for compatibility with most sieve shakers and testing protocols. The brass frame offers structural rigidity and resistance to corrosion, while the stainless steel wire cloth ensures accurate particle separation.
The #8 USA Series designation refers to the mesh size of the wire cloth, which corresponds to a sieve opening of 2.36 mm (0.0929″). This specific opening size is essential for separating particles within a defined range, meeting the requirements of various testing standards. The full height design, with a 5.08cm (2″) depth to wire, allows for larger sample volumes and reduces the risk of overflow during the sieving process.
These specifications matter because they directly impact the precision and reliability of the testing results. The brass frame provides long-term durability, ensuring the sieve maintains its shape and dimensions under repeated use. The stainless steel wire cloth offers superior resistance to corrosion and abrasion, preventing contamination of the samples and maintaining accurate particle separation. The specific mesh size and full height design enable precise and efficient analysis of a wide range of materials.
