After several months of consistent use, the VWR Testing Sieves, All Brass 50BB8H Half Height have proven to be incredibly reliable. The sieves have maintained their structural integrity and accuracy over time. This is critical when conducting many tests, one after the other.

Durability has been a strong point; there are minimal signs of wear and tear despite frequent use and exposure to various materials. The brass construction has held up well, showing only minor discoloration.

Maintaining these sieves is quite simple. A gentle brush and occasional cleaning with a mild soap solution are sufficient to keep them in excellent condition. Compared to previous sieves I’ve used, the VWR sieves require less maintenance and consistently deliver superior performance.

Breaking Down the Features of VWR Testing Sieves, All Brass 50BB8H Half Height

Specifications

• Diameter: 20.3 cm (8 inches). This standard diameter ensures compatibility with most sieve shakers.
• Height: Half height, with a 2.54cm (1 inch) depth above the wire cloth. The half-height design facilitates easier handling of smaller sample sizes.
• Frame Material: Brass. Brass provides durability and resistance to corrosion.
• Wire Cloth Material: Brass. The brass wire cloth ensures accurate particle separation and long-lasting performance.
• USA Series: #50. The USA Series number indicates the mesh size and corresponding sieve opening.
• Sieve Opening: 300 µm (0.0118 inches). This determines the size of particles that will pass through the sieve.
• Compliance: Meets applicable ASTM E-11 and ISO specifications. Meeting these standards ensures the sieve’s accuracy and reliability.
• Traceability: Each sieve bears a traceable serial number and comes with a certificate of compliance. This guarantees the sieve’s quality and traceability to national standards.

These specifications are critical for ensuring accurate and consistent particle size analysis. The standardized dimensions and high-quality materials contribute to the overall user experience. Meeting ASTM E-11 and ISO specifications is paramount, making these sieves a reliable tool for any laboratory professional.
