VWR Test Sieve St Steel #200 200SS12F Review

The VWR Test Sieve St Steel #200 200SS12F: Review from Real Use

The VWR Test Sieve St Steel #200 200SS12F from VWR isn’t exactly the kind of gear you’d take on a backcountry trek or rely on in a survival situation. However, in the world of material analysis, this 12-inch diameter sieve with its #200 mesh size is a crucial piece of equipment. It’s a tool designed for precision particle separation, and while it might not stop a charging bear, it can certainly ensure the accuracy of critical industrial or scientific processes.

My introduction to test sieves came during my time consulting for a soil remediation project. We needed to accurately determine the particle size distribution of contaminated soil samples to optimize the treatment process. After inconsistent results with cheaper sieves, it became clear we needed a reliable solution, leading me to the VWR Test Sieve St Steel #200 200SS12F.

The sieve arrived well-packaged. My initial impression was the robust build quality. The stainless steel frame felt solid, and the mesh was taut and uniform. Compared to some of the cheaper brass-framed sieves I’d used previously, this one felt like a significant upgrade. I also looked at sieves from Advantech and Gilson, but the VWR offered a better combination of price and certified precision. I was cautiously optimistic, hoping this would solve our consistency issues.


Real-World Testing: Putting VWR Test Sieve St Steel #200 200SS12F to the Test

First Use Experience

My first test with the VWR Test Sieve St Steel #200 200SS12F involved analyzing a batch of sediment collected from a local riverbed. The goal was to determine the fine particulate matter content to assess potential erosion impacts from nearby construction. The VWR sieve was used as part of a stack, positioned below larger mesh sieves to isolate the #200 (75 micron) particles.

The sieve performed flawlessly, allowing for efficient separation of the fine sediment. Its rigid construction prevented any warping or flexing during the sieving process, ensuring consistent and accurate results. There was a noticeable difference compared to the older sieves, which often required multiple passes to achieve comparable separation. The ease of use was immediately apparent, and I felt confident in the data we were collecting.

Extended Use & Reliability

After several weeks of continuous use, the VWR Test Sieve St Steel #200 200SS12F has proven to be a reliable and durable tool. We’ve used it to analyze hundreds of soil, sediment, and aggregate samples. There has been no noticeable degradation in the mesh or frame. The stainless steel construction has also held up well to repeated washing and cleaning.

Maintaining the sieve is simple; a gentle brush and mild detergent are all that’s needed to remove any accumulated particles. Compared to previous experiences with less durable sieves that required frequent repairs or replacements, the VWR sieve has been a significant improvement. It’s saved us both time and money in the long run.
