Real-World Testing: Putting VWR Testing Sieves, 12 Brass Frame, Stainless Steel Wire Cloth 170BS12F Full Height to the Test
First Use Experience
My first test involved analyzing a particularly challenging batch of clay-rich soil from a construction site. The sample was notorious for clumping and requiring extensive manual separation, which I used to perform with my old sieves. Using the VWR Testing Sieves, 12 Brass Frame, Stainless Steel Wire Cloth 170BS12F Full Height, I was immediately impressed by how easily the material passed through the 90 µm mesh, even when slightly damp.
The sieve performed flawlessly in both dry and slightly damp conditions, maintaining consistent separation. Its large diameter allowed me to process the entire sample in one go, significantly reducing processing time. There were no unexpected issues, just a noticeable improvement in efficiency and ease of use compared to my old setup.
Extended Use & Reliability
After several weeks of continuous use, the VWR Testing Sieves, 12 Brass Frame, Stainless Steel Wire Cloth 170BS12F Full Height continues to perform at its peak. There are no signs of wear and tear on the brass frame or the stainless steel mesh. I’ve processed hundreds of soil samples, from coarse gravel to fine silt, without any degradation in performance.
Maintenance is simple: a gentle brush and occasional cleaning with mild detergent keeps the mesh free of debris. I’ve found the brass frame to be surprisingly resistant to corrosion. Comparing this to my previous sieves, where the mesh would stretch and distort after only a few uses, the VWR sieve has exceeded all expectations.
