Real-World Testing: Putting VWR Testing Sieves, 12 Brass Frame, Stainless Steel Wire Cloth PB12HX Accessories to the Test
First Use Experience
I first tested the VWR Testing Sieves, 12 Brass Frame, Stainless Steel Wire Cloth PB12HX Accessories in my lab, analyzing soil samples collected from a brownfield site. The sieves were used to separate the soil into different particle size fractions, allowing for detailed analysis of each fraction.
The sieves performed admirably, even with damp and slightly clumpy soil samples. Their large diameter allowed for efficient sieving of larger sample volumes, and the smooth surfaces of the brass frame and steel mesh minimized material retention.
Using these sieves was straightforward; nesting them together in a stack was effortless. The tight fit between each sieve prevented any cross-contamination between different particle size fractions.
My initial use revealed one minor issue: static cling. Fine particles tended to adhere to the stainless steel mesh, requiring gentle brushing to ensure all material passed through.
Extended Use & Reliability
After several weeks of consistent use, the VWR Testing Sieves, 12 Brass Frame, Stainless Steel Wire Cloth PB12HX Accessories have held up remarkably well. The brass frame shows no signs of deformation, and the stainless steel mesh remains taut and undamaged.
I have noticed minimal wear and tear, even with rigorous use and frequent cleaning. The sieves appear as robust as the day I received them.
Cleaning the sieves is simple, requiring only a soft brush and mild detergent. Regular cleaning is essential to prevent clogging and maintain accuracy.
Compared to my previous sieves, the VWR Testing Sieves, 12 Brass Frame, Stainless Steel Wire Cloth PB12HX Accessories have proven to be significantly more durable and reliable. Their consistent performance has given me confidence in the accuracy of my particle size analyses.
