Breaking Down the Features of VWR Testing Sieves, All Brass 100BB8H Half Height
Specifications
- Diameter: 20.3 cm (8 inches). This standard diameter ensures compatibility with most sieve shakers and testing equipment.
- Height: Half Height (2.54 cm / 1 inch depth above wire). The half-height design facilitates easier handling and reduces the overall height of sieve stacks.
- Frame Material: Brass. Brass offers excellent corrosion resistance and durability, ensuring a long lifespan.
- Wire Cloth Material: Brass. Matching the frame material, the brass wire cloth maintains consistency and minimizes the risk of galvanic corrosion.
- USA Series: #100. This designation indicates the sieve’s mesh size according to the USA standard.
- Sieve Opening: 150 µm (0.0059 inches). The 150-micrometer opening allows for precise separation of particles within that size range.
- Compliance: ASTM E-11 and ISO specifications. Adherence to these standards ensures the sieve’s accuracy and reliability.
- Construction: Fillet solder bead between the frame and wire cloth. This prevents particles from getting trapped and ensures accurate sieving.
These specifications are critical for reliable particle size analysis. The precise sieve opening guarantees accurate separation. The durable construction ensures that the sieve will maintain its integrity over time.
