Real-World Testing: Putting VWR Testing Sieves, All Stainless Steel 80SS8H Half Height to the Test
First Use Experience
Our initial testing involved analyzing soil samples from a local brownfield site known to have varying particle sizes. We needed to determine the particle size distribution to assess the potential for contaminant transport. The VWR Testing Sieves, All Stainless Steel 80SS8H Half Height was integrated into a standard sieve stack, and the sample was mechanically shaken for a set duration.
The sieve performed admirably, even with slightly damp soil. The stainless-steel mesh didn’t clog easily, and the half-height design made it easier to observe the sample during the sieving process. I found that the half-height design allowed better airflow and improved separation compared to full-height sieves I’ve used in the past.
The only minor issue was ensuring the sieve was perfectly level within the stack to prevent any uneven distribution of particles. This is a common concern with any sieve but was easily addressed with careful setup.
Extended Use & Reliability
After several months of regular use, the VWR Testing Sieves, All Stainless Steel 80SS8H Half Height has proven to be a reliable workhorse. It’s been used in a range of environmental projects, including sediment analysis and industrial waste characterization.
The sieve has shown no signs of significant wear and tear. The stainless-steel frame and mesh remain structurally sound, and there is no evidence of corrosion or distortion. The fillet solder bead between the frame and wire cloth, a thoughtful design element, has effectively prevented particles from getting trapped.
Maintenance is straightforward. After each use, the sieve is gently brushed with a soft-bristled brush and rinsed with deionized water. Occasionally, we use an ultrasonic cleaner to remove any stubborn particles. This is far easier than cleaning the old brass sieves.
Compared to our previous experiences with brass sieves, the VWR Testing Sieves, All Stainless Steel 80SS8H Half Height offers significantly improved reliability and reduced contamination risk. The consistent and accurate results have increased our confidence in our data and streamlined our reporting process.
