Real-World Testing: Putting VWR Testing Sieves, All Stainless Steel 140SS8H Half Height to the Test
First Use Experience
I first tested the VWR Testing Sieves, All Stainless Steel 140SS8H Half Height during a soil analysis project in the high desert of Nevada. The testing involved separating soil samples into different particle size fractions to determine their composition and suitability for various engineering applications. The harsh desert environment presented several challenges, including extreme temperature fluctuations, high winds, and abrasive dust.
The sieves performed admirably in these demanding conditions. The stainless steel construction proved resistant to corrosion and abrasion, and the half-height design made them easy to handle even when wearing gloves. The sieves easily handled the fine sand and coarser gravel encountered in the desert soil.
The sieves proved surprisingly easy to use, even for someone accustomed to more rudimentary methods of particle separation. After experimenting with different sieving techniques, I quickly found a method that provided consistent and accurate results. I noticed that the half-height design was a bonus when using it on an uneven surface such as over rocks and small hills.
One minor issue was that the fine mesh of the #140 sieve (106 µm opening) tended to clog with fine dust particles, requiring occasional cleaning with a brush. However, this was a minor inconvenience and easily remedied. Overall, the initial testing experience was overwhelmingly positive.
Extended Use & Reliability
After several months of regular use in diverse environments, including coastal beaches, mountain forests, and construction sites, the VWR Testing Sieves, All Stainless Steel 140SS8H Half Height have consistently performed to a high standard. The sieves have held up remarkably well, with no signs of significant wear and tear. The all-stainless steel construction continues to resist corrosion, even after exposure to saltwater and acidic soil.
Despite rigorous handling, the sieve mesh remains intact, and the frame shows no signs of deformation. The sturdy construction of the VWR Testing Sieves, All Stainless Steel 140SS8H Half Height is truly a testament to its ability to handle tough environments.
Maintaining the sieves is straightforward. After each use, I simply brush them clean with a soft brush and, if necessary, wash them with mild soap and water. I always ensure the sieves are completely dry before storing them to prevent any corrosion.
Compared to my previous experiences with less robust sieves, the VWR Testing Sieves, All Stainless Steel 140SS8H Half Height have proven to be a significant improvement in terms of durability, accuracy, and ease of use. They have significantly outperformed my expectations and have become an indispensable tool in my material analysis toolkit.
Breaking Down the Features of VWR Testing Sieves, All Stainless Steel 140SS8H Half Height
Specifications
- The VWR Testing Sieves, All Stainless Steel 140SS8H Half Height features an 8-inch (20.3 cm) diameter, which is a standard size for laboratory testing sieves. This diameter provides a sufficient surface area for efficient particle separation.
- The sieve has a half-height design, with a 2.54 cm (1 inch) depth to the wire. This reduced height makes the sieve more portable and easier to handle, especially in field applications.
- The sieve is constructed entirely of stainless steel, including the frame and wire cloth. This material provides excellent corrosion resistance, durability, and reduces the likelihood of metallic sample contamination.
- The sieve has a USA Series number of #140, indicating the mesh size. This correlates to a sieve opening of 106 µm (0.0042 inches).
- The sieves are inspected using an optical measurement system traceable to the National Institute of Standards and Technology (NIST). Each sieve has a traceable serial number and comes with a certificate of compliance to applicable ASTM E-11 and ISO specifications.
These specifications are crucial because they ensure the accuracy and reliability of the particle size analysis.
