Breaking Down the Features of VWR Testing Sieves, All Stainless Steel 100SS8H Half Height
Specifications
- USA Series: #100. This indicates the sieve is manufactured to comply with USA standards.
- Sieve Opening: 150 µm (0.0059″). This defines the size of the openings in the mesh, allowing only particles smaller than 150 micrometers to pass through.
- All stainless steel construction: Provides excellent corrosion resistance and prevents metallic contamination of samples. This feature ensures longevity and accuracy.
- Half-height design (2.54cm / 1″ depth to wire): Offers easier handling and reduces the overall weight of sieve stacks. This is especially beneficial when working with numerous samples.
- 8″ Diameter: A standard size for testing sieves, fitting most sieve shakers and allowing for consistent comparisons.
- Certificate of Compliance: Ensures that the sieve meets the requirements of ASTM E-11 and ISO specifications. This guarantees accuracy and traceability.
- Individually Boxed: Protects the sieve during shipping and storage.
These specifications are crucial because they directly impact the accuracy and reliability of particle size analysis. The stainless steel construction minimizes contamination, while the precise sieve opening ensures consistent separation.
