Real-World Testing: Putting VWR Testing Sieves, 8 Brass Frame, Stainless Steel Wire Cloth 18BS8F Full Height to the Test
First Use Experience
My first use of the VWR Testing Sieves, 8 Brass Frame, Stainless Steel Wire Cloth 18BS8F Full Height was in the lab, analyzing a batch of fine aggregate for a high-strength concrete mix. The sieve fit snugly into my existing sieve shaker, and the process of separating the aggregate into different size fractions was straightforward. The stainless steel mesh allowed for efficient particle passage without clogging, even with slightly damp material.
I observed no deformation of the mesh or frame during the initial test, even with the shaker running at full speed. The ease of use was notable; no learning curve was required. This was a significant improvement over some of the older sieves I’ve used that required constant adjustments and cleaning to prevent blinding.
Extended Use & Reliability
After several months of regular use, the VWR Testing Sieves, 8 Brass Frame, Stainless Steel Wire Cloth 18BS8F Full Height has proven to be a reliable and durable tool. There is no noticeable wear and tear on either the brass frame or the stainless steel mesh, despite being subjected to thousands of agitation cycles in the shaker. Regular cleaning with a soft brush and mild detergent has kept it in excellent condition.
The sieve’s ability to maintain its dimensional accuracy and structural integrity over time has been impressive. I’ve previously encountered sieves where the mesh would stretch or warp after prolonged use, leading to inaccurate results. This VWR sieve has outperformed those experiences considerably.
Breaking Down the Features of VWR Testing Sieves, 8 Brass Frame, Stainless Steel Wire Cloth 18BS8F Full Height
Specifications
The VWR Testing Sieves, 8 Brass Frame, Stainless Steel Wire Cloth 18BS8F Full Height boasts several key specifications that contribute to its performance:
- Frame Material: 8″ Brass Frame. Brass offers excellent durability and resistance to corrosion compared to some other metals.
- Wire Cloth Material: Stainless Steel Wire Cloth. Stainless steel provides superior resistance to abrasion and chemical attack, ensuring accurate particle separation over time.
- Sieve Opening: 1.00 mm (0.0394″). This defines the specific particle size that will pass through the sieve.
- USA Series: #18. Denotes the mesh size according to the USA standard.
- Height: Full Height (2″ depth to wire). This greater depth offers increased capacity and reduces the risk of material overflowing.
These specifications are critical because they directly impact the sieve’s accuracy and longevity. The brass frame ensures structural integrity, while the stainless steel mesh maintains consistent pore size for reliable particle separation. The full height allows for larger sample volumes, making it suitable for a wider range of applications.
