Breaking Down the Features of VWR Testing Sieves, 8 Brass Frame, Stainless Steel Wire Cloth 635BS8H Half Height

Specifications

• Frame Material: Brass. The brass frame provides a rigid and durable structure, resisting deformation under pressure.
• Wire Cloth Material: Stainless Steel. Stainless steel offers excellent corrosion resistance and durability, ensuring accurate and consistent results over time.
• Diameter: 8 inches (20.32cm). The 8-inch diameter provides a sufficient surface area for efficient sieving of various sample sizes.
• Height: Half Height (2.54cm/1″ depth to wire). The half-height design reduces the overall height, making it easier to handle and store, especially when using multiple sieves simultaneously.
• USA Series: #635. This designation indicates the specific mesh size of the sieve.
• Sieve Opening: 20 µm (0.0008″). The 20-micron opening is ideal for analyzing fine particles, providing precise separation.
• Compliance: ASTM E-11 and ISO specifications. Compliance with these standards ensures the sieve meets rigorous quality control requirements.
• Certification: Traceable serial number and certificate of compliance to applicable ASTM E-11 and ISO specifications. Traceability to NIST standards provides assurance of accuracy and reliability.

These specifications are crucial for ensuring accurate and reproducible results. The quality of the materials and the precision of the mesh size directly impact the reliability of the particle analysis. The NIST traceability is particularly important for applications where accuracy is paramount.

Performance & Functionality

The VWR Testing Sieves, 8 Brass Frame, Stainless Steel Wire Cloth 635BS8H Half Height excels in its primary function: accurately separating particles based on size. The precision of the mesh ensures consistent results, and the robust construction minimizes the risk of damage or deformation. Usability is also excellent, thanks to the convenient half-height design.

The sieve’s greatest strength is its accuracy and reliability. The only potential weakness is its relatively high price, but this is offset by its long-term durability and performance. Overall, it exceeds my expectations.
