Real-World Testing: Putting VWR Testing Sieves, All Brass 14BB8H Half Height to the Test

First Use Experience

Our first use of the VWR Testing Sieves, All Brass 14BB8H Half Height was in our on-site lab. We were analyzing a batch of soil samples from a former industrial site. We needed to determine the particle size distribution to assess potential contaminant binding. The sieves were used in a stack, with the 14BB8H as one of the critical layers.

The sieves performed admirably, even with the somewhat damp and clumpy soil we were dealing with. The half-height design made it easy to shake and manipulate the sieves, even when wearing gloves. The process was considerably more efficient than our previous method, which involved more manual sifting and less consistent results.

There weren’t any major issues. However, we did notice a small amount of fine material getting trapped in the fillet solder bead between the frame and wire cloth initially. This was easily resolved with a quick cleaning.

Extended Use & Reliability

After several weeks of continuous use, the VWR Testing Sieves, All Brass 14BB8H Half Height have held up exceptionally well. We’ve processed hundreds of samples, and the mesh integrity remains intact.

There are some minor scratches on the brass frame from handling, but nothing that affects the sieve’s performance. The brass still looks great! The mesh shows no signs of stretching or distortion.

Maintenance involves simply brushing the mesh after each use and occasionally washing the sieves with mild soap and water. This has proven sufficient to keep them clean and functioning optimally. It’s also important to fully dry the sieves after washing to prevent corrosion.

Compared to our previous experience with cheaper sieves, the VWR Testing Sieves, All Brass 14BB8H Half Height have been a revelation. They provide more consistent and accurate results, and their durability is significantly better. This has led to increased confidence in our data and more efficient lab operations.
