Real-World Testing: Putting VWR Testing Sieves, 12 Brass Frame, Stainless Steel Wire Cloth 100BS12F Full Height to the Test
First Use Experience
I first tested the VWR Testing Sieves, 12 Brass Frame, Stainless Steel Wire Cloth 100BS12F Full Height in my lab, processing a batch of soil samples collected from a local construction site. The samples needed a thorough examination to determine particle size distribution.
The sieves performed admirably, even with damp and slightly clumpy soil. The full height of the sieve allowed for a larger sample volume without overflowing.
Using the sieves was straightforward; no real learning curve to speak of. Simply pour the sample into the top sieve and shake, either manually or with a mechanical shaker.
The only initial issue was static cling with very fine particles, which I resolved by gently tapping the frame. Static cling can be a nuisance with any fine mesh sieve.
Extended Use & Reliability
After several months of regular use, the VWR sieves have maintained their integrity and accuracy. The stainless steel wire cloth shows no signs of stretching or distortion.
The brass frame has proven to be incredibly durable, resisting dents and scratches from accidental bumps and drops. Occasional cleaning is all that is needed to keep the sieves in prime condition.
Compared to my previous sieves, which required frequent retensioning and repair, the VWR sieves have been a breath of fresh air. They consistently outperform my older, less expensive sieves in terms of both accuracy and durability.
Breaking Down the Features of VWR Testing Sieves, 12 Brass Frame, Stainless Steel Wire Cloth 100BS12F Full Height
Specifications
- The VWR Testing Sieves, 12 Brass Frame, Stainless Steel Wire Cloth 100BS12F Full Height features a 12-inch (30.5 cm) diameter brass frame. This size is ideal for handling larger sample volumes, speeding up the sieving process.
- The sieve utilizes stainless steel wire cloth with a #100 USA Series designation, corresponding to a sieve opening of 150 µm (0.0059 inches). This specific mesh size is crucial for separating fine particles in soil, powders, and other granular materials.
- It is a full-height sieve, with a depth to cloth of 8.3cm (3 1/4″). The greater depth is beneficial when processing larger or denser samples, preventing overflow and ensuring thorough separation.
- Each sieve is inspected with an optical measurement system traceable to the National Institute of Standards and Technology (NIST). This traceability ensures the accuracy and reliability of the sieve for critical applications.
- The product comes with a certificate of compliance applicable to ASTM E-11 and ISO specifications. Compliance with these standards guarantees that the sieve meets strict quality control requirements for testing and analysis.
These specifications are vital because they directly impact the accuracy and efficiency of particle size analysis. Precise mesh size, durable construction, and NIST traceability are all essential for obtaining reliable results.
Performance & Functionality
The VWR Testing Sieves, 12 Brass Frame, Stainless Steel Wire Cloth 100BS12F Full Height performs its job exceptionally well, providing accurate and consistent particle size separation. The precise mesh size ensures that only particles smaller than 150 µm pass through.
The primary strength is its reliability and accuracy; I can trust that each sieve will consistently provide the same results. One area for potential improvement might be an integrated brush for easier cleaning of the mesh, although this is a minor consideration.
The sieve meets and exceeds my expectations for a high-quality testing sieve. Its performance and durability are significantly better than cheaper alternatives.
