Real-World Testing: Putting VWR Deep Frame Washing Sieves 100BS8W4W/SU 4″ Depth Sieves With #20 Support Cloth to the Test
First Use Experience
My first test involved separating extremely fine clay particles from a soil sample collected after a particularly dusty training exercise. I set up the VWR Deep Frame Washing Sieves 100BS8W4W/SU 4″ Depth Sieves With #20 Support Cloth in a laboratory sink and gently ran water over the sample. The deep frame allowed for a good amount of material to be processed at once without overflowing.
The #20 support cloth was essential, providing backing to prevent the finer mesh from warping under the weight of the wet sample. The sieve performed admirably, quickly separating the clay while retaining the larger particles efficiently. Cleanup was surprisingly easy.
There were no initial issues, and I immediately noticed the increased efficiency compared to my older sieves.
Extended Use & Reliability
After several weeks of using the VWR Deep Frame Washing Sieves 100BS8W4W/SU 4″ Depth Sieves With #20 Support Cloth on various soil and sediment samples, I can attest to its durability. There are no signs of wear or deformation on the wire cloth or the brass frame. The deep frame design also proved particularly helpful when processing larger sample volumes.
Maintenance is straightforward. A simple rinse with water and a gentle brush are all that’s needed to keep the sieve clean and functioning optimally. It outperforms my previous sieves in terms of both efficiency and longevity, showing no signs of weakening.
