Let’s Dive into VWR Deep Frame Washing Sieves 120BS8W8 8″ Depth Sieves
The VWR Deep Frame Washing Sieves 120BS8W8 8″ Depth Sieves aren’t your everyday piece of kit; they’re precision tools designed for a specific, but crucial, task: the meticulous washing and separation of fine powder samples. Manufactured by VWR, these sieves boast a heavy-duty brass frame, stainless steel wire cloth, and an 8-inch depth for handling larger sample volumes. This promises durability and accuracy, critical for reliable results in various applications.
My work often involves analyzing soil samples from archaeological digs, and the inconsistency in particle size after basic washing always bugged me. The VWR Deep Frame Washing Sieves 120BS8W8 8″ Depth Sieves seemed like a solution to standardize and improve the accuracy of my pre-analysis sample preparation. Upon unboxing, the first thing that struck me was the substantial weight and robust construction. The brass frame feels incredibly solid, and the stainless steel mesh is taut and evenly woven.
Compared to cheaper, mass-produced sieves I’ve used in the past, which often feature flimsy plastic frames and uneven mesh, the VWR sieves feel like a serious upgrade. I considered the Advantech 8″ diameter sieves, which are more readily available but have a lighter-duty construction, and the Gilson Testing Screen, which offers a similar build quality but at a significantly higher price point. Ultimately, the VWR sieves offered the best balance of quality, capacity, and price for my needs. My first impression was one of cautious optimism.
Real-World Testing: Putting VWR Deep Frame Washing Sieves 120BS8W8 8″ Depth Sieves to the Test
First Use Experience
My initial test involved processing a batch of clay-rich soil samples collected from a recent excavation site. I set up the sieve under a gentle stream of water, carefully pouring the soil slurry onto the mesh. The 8-inch depth proved invaluable, preventing overflow and allowing me to wash larger samples at once. The sieve’s sturdy construction meant it didn’t warp or flex under the weight of the wet soil, unlike some of the flimsier sieves I’ve used before.
The VWR Deep Frame Washing Sieves 120BS8W8 8″ Depth Sieves performed admirably in removing the fine clay particles, leaving behind the larger sand and gravel components. Even after repeated washes, the stainless steel mesh showed no signs of clogging or damage. I was initially concerned about the fine #120 mesh (125 µm) being too delicate, but it held up surprisingly well.
Extended Use & Reliability
After several weeks of using the VWR Deep Frame Washing Sieves 120BS8W8 8″ Depth Sieves almost daily, I can confidently say that they are built to last. There’s been no noticeable wear and tear on the frame or mesh, despite the constant exposure to water, soil, and occasional abrasive particles. The sieves are surprisingly easy to clean. A quick rinse under running water, followed by a gentle scrub with a soft brush, is usually sufficient to remove any residue.
Compared to my previous sieves, which required frequent replacements due to damaged frames and stretched mesh, the VWR sieves have significantly reduced my maintenance costs and downtime. They consistently outperform any other sieves I’ve used in terms of durability, capacity, and ease of use.
Breaking Down the Features of VWR Deep Frame Washing Sieves 120BS8W8 8″ Depth Sieves
Specifications
- Manufacturer: VWR.
- Frame Material: Heavyweight seamless brass. This provides exceptional strength and corrosion resistance, ensuring the sieve maintains its shape and integrity over time.
- Mesh Material: Stainless steel wire cloth. Stainless steel is highly durable, resistant to corrosion, and provides consistent pore sizes for accurate particle separation.
- Sieve Depth: 8 inches (20.3cm). This allows for processing larger volumes of sample material without overflow or loss.
- Sieve Diameter: 8 inches (20.3cm). This is a standard size, making it compatible with most conventional pans and covers.
- USA Series: #120.
- Sieve Opening: 125 µm (0.0049″). This opening size is ideal for separating fine particles, such as silt and fine sand.
These specifications translate directly into performance benefits. The brass frame ensures the sieve won’t warp or deform under heavy use, while the stainless steel mesh guarantees consistent and accurate particle separation. The 8-inch depth maximizes throughput, saving time and effort.
Performance & Functionality
The VWR Deep Frame Washing Sieves 120BS8W8 8″ Depth Sieves excels at its primary function: separating fine particles from larger aggregates. The 125 µm mesh is precisely woven, resulting in consistent and reproducible results. The large depth and sturdy frame allow for efficient washing of even large and heavy soil samples.
One minor weakness is that the brass frame can tarnish over time, although this doesn’t affect the sieve’s performance. Overall, the sieves significantly exceed my expectations in terms of performance and durability.
Design & Ergonomics
The sieves boast a simple, functional design. The heavyweight brass frame provides a solid, stable platform, and the stainless steel mesh is securely attached. The sieves are easy to handle, even when full of wet material. There’s no learning curve involved; anyone familiar with basic laboratory equipment can use them effectively.
Durability & Maintenance
Given the robust construction and high-quality materials, the VWR Deep Frame Washing Sieves 120BS8W8 8″ Depth Sieves should last for many years with proper care. Cleaning is simple and straightforward, requiring only water and a soft brush. Regular inspection of the mesh for any signs of damage is recommended.
Accessories and Customization Options
The VWR Deep Frame Washing Sieves 120BS8W8 8″ Depth Sieves are designed to be compatible with standard 8-inch sieve pans and covers, allowing for easy stacking and containment of samples. VWR also offers a CENTERLINE® measurement (47730-590) which is a NIST traceable service that checks calibration and gives statistical measurement information on each sieve. The sieves can be used with a variety of laboratory stands and shakers for automated processing. While there are no readily available “customization” options in the traditional sense, the ability to stack sieves with different mesh sizes allows for a customized particle separation process.
