The VWR Deep Frame Washing Sieves 120BS8W8W/SU 8″ Depth Sieves With #20 Support Cloth are laboratory tools designed for washing fine powder samples. Manufactured by VWR, these sieves combine a heavy-duty brass frame with durable stainless-steel wire cloth. They are essential equipment for various civil engineering, fine ceramic, paint/pigment, and other applications where precise particle separation is critical.
My work in environmental science often requires analyzing soil samples for contaminants. This necessitates thoroughly washing the soil to isolate specific particle sizes and remove organic matter. I’d been struggling with inconsistent results using makeshift sieves.
My first impression upon receiving the VWR Deep Frame Washing Sieves 120BS8W8W/SU 8″ Depth Sieves With #20 Support Cloth was positive. The build felt solid and professional, the brass frame substantial, and the mesh appeared taut and uniform. The 8″ depth gave me confidence I could process a decent amount of material at once.
Before choosing this set, I considered using a set of generic stainless-steel kitchen sieves. They lacked the precision and durability required for lab work. I also briefly explored a high-end sonic sifter. But the VWR sieves struck the perfect balance of quality and affordability.
Initially, I was excited about the potential for increased efficiency and reliability in my lab work. I hoped these sieves would eliminate the variability I’d been experiencing, though I also knew lab equipment can sometimes be finicky.
Real-World Testing: Putting VWR Deep Frame Washing Sieves 120BS8W8W/SU 8″ Depth Sieves With #20 Support Cloth to the Test
First Use Experience
My first test was washing a batch of soil samples collected from a former industrial site. I needed to separate the soil into various particle sizes to analyze heavy metal contamination. The sieves were used under running tap water in the lab sink.
The sieves performed exceptionally well, even when exposed to silty sediment. The deep frame handled a relatively large soil volume without overflowing. The mesh remained intact and did not clog excessively during the washing process.
The sieves felt intuitive. I had no difficulty adapting to the washing procedure; It mirrored the traditional washing and sieving techniques. I found the depth of the sieve quite helpful in preventing splash over.
I was pleasantly surprised by how easily the fine particles passed through the #120 mesh, while larger debris was effectively retained. No immediate issues arose, bolstering my initial impression.
Extended Use & Reliability
After several weeks of frequent use, the VWR Deep Frame Washing Sieves 120BS8W8W/SU 8″ Depth Sieves With #20 Support Cloth have proven to be a reliable tool. I’ve used them for several different soil samples, and types of sediments. There has been no detectable degradation.
The sieves have demonstrated good durability, with no signs of frame warping or mesh detachment. The stainless-steel wire cloth is resilient and shows no rust or corrosion.
Maintaining the sieves is simple: a thorough rinse with water after each use keeps them clean. A soft brush removes any stubborn particles. I avoid using harsh chemicals to protect the integrity of the mesh.
These sieves far outperform my previous jury-rigged setup, providing consistent and reproducible results. My confidence in the accuracy of my lab analyses has improved considerably.
