Real-World Testing: Putting VWR Testing Sieves, All Stainless Steel 170SS8H Half Height to the Test

First Use Experience

Our first use of the VWR Testing Sieves, All Stainless Steel 170SS8H Half Height was in analyzing soil samples collected from a contaminated site. We used a stack of sieves with varying mesh sizes, including the 170SS8H, to separate the soil particles for further analysis. The sieves were used in conjunction with a mechanical sieve shaker.

The sieves performed admirably in the challenging environment; even with damp soil, the stainless-steel mesh remained clear and free from clogging. The half-height design made it easier to load and unload samples, reducing the risk of spills. The consistent mesh size ensured a uniform separation of particles.

The sieves were incredibly easy to use. Minimal training was needed for our technicians. The tight fit of the sieves in the stack prevented any material bypass, which improved the accuracy of our results.

After the first use, I was struck by how much cleaner and more efficient the sieving process was compared to our old brass sieves. The stainless steel was easy to clean, and there were no signs of corrosion or damage. This was a significant improvement.

Extended Use & Reliability

After several months of regular use, the VWR Testing Sieves, All Stainless Steel 170SS8H Half Height have proven to be exceptionally durable and reliable. We’ve used them to analyze hundreds of soil, sediment, and powder samples. We’ve consistently obtained consistent and accurate results.

There are virtually no signs of wear and tear. The stainless-steel frames and mesh show no corrosion, distortion, or damage, even with frequent use and cleaning. These sieves still look and perform as if they were brand new.

Maintenance is straightforward; we simply brush off any loose material and then wash the sieves with mild detergent and water. They dry quickly, and the smooth surfaces prevent any residue from accumulating. A nylon brush is used to remove any stuck particles.

Compared to our previous experiences with brass sieves, the VWR Testing Sieves, All Stainless Steel 170SS8H Half Height are a clear winner. They have eliminated the problem of brass contamination. Furthermore, their durability and ease of use have significantly improved the efficiency and reliability of our particle size analysis.

Breaking Down the Features of VWR Testing Sieves, All Stainless Steel 170SS8H Half Height

Specifications

• USA Series: #170. This designation indicates the sieve’s mesh size according to the USA standard.
• Sieve Opening: 90 µm (0.0035″). This specifies the precise size of the openings in the sieve mesh, dictating the size of particles that will pass through.
• Construction: All Stainless Steel. This highlights the use of stainless steel for both the frame and the mesh, providing superior corrosion resistance and durability.
• Height: Half Height (2.54cm / 1″ depth to wire). This refers to the shorter height of the sieve, making it easier to handle and reducing material volume.
• Diameter: 20.3cm (8″). This is the standard diameter for testing sieves, ensuring compatibility with most sieve shakers and stacking systems.
• Compliance: Meets ASTM E-11 and ISO specifications. This ensures that the sieve meets rigorous quality and accuracy standards.
• Traceability: Each sieve bears a traceable serial number and comes with a certificate of compliance to applicable ASTM E-11 and ISO specifications.
