The half-height design was appealing for its manageable size and potential for easy stacking, saving valuable lab space.

Unboxing the VWR Testing Sieves, 12 Brass Frame, Stainless Steel Wire Cloth 200BS12H Half Height, my first impression was one of solid construction. The brass frame felt robust, and the stainless-steel wire cloth appeared taut and evenly woven. The build quality seemed superior to cheaper sieves I had used in the past.

I considered other sieves from Gilson and Humboldt Mfg. Co., but ultimately chose the VWR sieves due to the combination of brass frame for durability, stainless steel mesh for corrosion resistance, and the half-height design that fit my space constraints. Plus, the included certificate of compliance to ASTM E-11 and ISO specifications gave me confidence in their accuracy. I also appreciated the availability of accessories like bottom pans and covers.

My initial excitement was high. The promise of precise particle separation and the assurance of NIST-traceable accuracy made me eager to put the VWR Testing Sieves, 12 Brass Frame, Stainless Steel Wire Cloth 200BS12H Half Height to work.

Real-World Testing: Putting VWR Testing Sieves, 12 Brass Frame, Stainless Steel Wire Cloth 200BS12H Half Height to the Test

First Use Experience

My first test of the VWR Testing Sieves, 12 Brass Frame, Stainless Steel Wire Cloth 200BS12H Half Height involved analyzing soil samples collected from a recent boot test in a muddy, wooded environment. I wanted to understand how different boot tread patterns affected soil displacement. I stacked the sieves, starting with the largest mesh size at the top and decreasing downwards, then poured the dried soil sample into the top sieve.

I placed the stack in a sieve shaker and ran it for 10 minutes. Then, I carefully weighed the amount of soil retained on each sieve to determine the particle size distribution. The process was straightforward, and the sieves felt sturdy throughout.

The mesh was very effective at separating the soil particles. After first use, the only issue was the fine dust that clung to the mesh, requiring thorough cleaning.

Extended Use & Reliability

After several weeks of using the VWR Testing Sieves, 12 Brass Frame, Stainless Steel Wire Cloth 200BS12H Half Height on various soil and aggregate samples, I’ve found them to be consistently reliable. The brass frame has held up well, with no signs of bending or warping.

There are no significant signs of wear and tear on the mesh so far. Cleaning the sieves after each use is crucial. I use a soft brush and mild detergent to prevent clogging of the mesh.

These sieves outperform previous, cheaper models I’ve used. The accuracy and durability are noticeably superior, and the consistent results give me confidence in my data.

Breaking Down the Features of VWR Testing Sieves, 12 Brass Frame, Stainless Steel Wire Cloth 200BS12H Half Height

Specifications

• Frame Material: The VWR Testing Sieves, 12 Brass Frame, Stainless Steel Wire Cloth 200BS12H Half Height features a 12-inch (30.5cm) brass frame, providing a robust and durable structure. This helps maintain the sieve’s shape and withstand repeated use and handling.
• Wire Cloth Material: The stainless steel wire cloth is resistant to corrosion and wear, ensuring accurate and consistent particle separation over time. This is a critical feature, preventing the mesh from distorting or degrading due to moisture or chemical exposure.
• Sieve Height: The half-height design (depth to cloth is 4.1cm (15/8″)) allows for easy handling and stacking, optimizing lab space and workflow. The reduced height also makes it easier to visually inspect the retained material.
• USA Series: The sieve is part of the USA Series #200, indicating its compliance with industry standards and specifications. This provides confidence in the sieve’s accuracy and reliability.
• Sieve Opening: The 75 µm (0.0030″) sieve opening allows for precise separation of fine particles. This is essential for applications requiring detailed particle size analysis.
• Compliance: Each sieve comes with a certificate of compliance applicable to ASTM E-11 and ISO specifications, ensuring traceability and accuracy. This certification is critical for quality control and regulatory compliance.
• Traceability: Every sieve has a traceable serial number, ensuring that its performance can be tracked and verified. This adds another layer of confidence in the product’s quality and reliability.

These specifications are important because they directly impact the accuracy, durability, and usability of the sieves. The brass frame provides structural integrity, while the stainless steel mesh ensures consistent and reliable particle separation. The half-height design is more practical in terms of size and ease of use for a lab environment.
