Real-World Testing: Putting VWR Testing Sieves, All Stainless Steel 170SS8H Half Height to the Test
First Use Experience
Our first application of the VWR Testing Sieves, All Stainless Steel 170SS8H Half Height was in analyzing a series of soil samples collected from a construction site. We used the sieves in conjunction with a mechanical sieve shaker to ensure consistent and reproducible separation of particle sizes. The 90 µm (0.0035″) sieve opening was exactly what we needed for this specific soil analysis.
The VWR sieve performed admirably, providing a clean and accurate separation of particles. The half-height design made it easy to nest multiple sieves together, and the smooth stainless steel surface facilitated the easy passage of material. We appreciated how smoothly the sieve stack was assembled for quick analysis of a variety of aggregate sizes.
The ease of use was immediately apparent. Unlike some of our older sieves with warped frames, the VWR Testing Sieves, All Stainless Steel 170SS8H Half Height stacked perfectly and sealed tightly, preventing any cross-contamination between size fractions. There were no issues or surprises, and the initial results were highly encouraging.
Extended Use & Reliability
After several months of regular use, the VWR Testing Sieves, All Stainless Steel 170SS8H Half Height has proven to be a reliable workhorse in our lab. The stainless steel construction has held up remarkably well, showing no signs of corrosion or degradation, even after repeated exposure to wet soil samples. The fillet solder bead is a very welcome touch as it makes cleaning of the sieve incredibly easy.
The durability of the VWR sieve has been impressive. We’ve subjected it to countless cycles of shaking, washing, and drying, and it still maintains its shape and integrity. The mesh remains taut and free of dents or tears, and the frame shows no signs of warping or bending. The fact that this sieve is individually boxed ensures protection during shipment.
Maintenance is a breeze. A quick rinse with water and a gentle scrub with a soft brush is all it takes to keep the VWR Testing Sieves, All Stainless Steel 170SS8H Half Height clean and ready for the next analysis. Compared to our older brass-framed sieves, which required constant vigilance to prevent corrosion, the VWR sieve is virtually maintenance-free.
Compared to our previous experiences with less durable sieves, the VWR sieve has significantly outperformed our expectations. Its robustness, accuracy, and ease of maintenance have made it an indispensable tool in our lab.
