VWR Deep Frame Washing Sieves 170BS8W4W/SU 4″ Depth Sieves With #20 Support Cloth Review

What Makes the VWR Deep Frame Washing Sieves 170BS8W4W/SU 4″ Depth Sieves With #20 Support Cloth Click?

As an outdoor and tactical gear specialist, I’ve learned that even the most seemingly mundane equipment can play a vital role in research, environmental science, or even tactical analysis. That’s why the VWR Deep Frame Washing Sieves 170BS8W4W/SU 4″ Depth Sieves With #20 Support Cloth caught my eye. These aren’t your average kitchen strainers.

My work often requires precise particle separation, whether I’m analyzing soil composition after a training exercise or assessing the sediment in a local river after a heavy rain. I needed something robust, reliable, and capable of handling fine materials without clogging or failing under pressure. I was tired of flimsy sieves that buckled and screens that tore.

The sieves arrived in a surprisingly sturdy box, well-protected by foam inserts. The first thing I noticed was the weight; these are heavy-duty. The brass frame felt incredibly solid in my hands. The stainless steel wire cloth (#20 support cloth) appeared taut and precisely woven. The build quality screamed professionalism.

I considered a couple of other options before landing on the VWR Deep Frame Washing Sieves. One was a cheaper set from an unknown brand, but the reviews complained about flimsy construction. Another was a high-end sonic sifter, but that was overkill for my current needs, and the price was astronomical. The VWR option seemed like the perfect balance of quality and value.

My initial impression was excitement tempered by caution. The quality was evident, but I wondered if the sieve opening size (90 µm) would truly meet my needs. The 4-inch depth also raised a question: would it be cumbersome to use? Only time and testing would tell.

Real-World Testing: Putting VWR Deep Frame Washing Sieves 170BS8W4W/SU 4″ Depth Sieves With #20 Support Cloth to the Test

First Use Experience

My first use of the VWR Deep Frame Washing Sieves was analyzing soil samples collected from a recent wilderness survival course training area. The location had a mix of sandy soil, clay, and some organic matter. I needed to separate the different particle sizes to assess the impact of the training on the surrounding environment.

I tested the sieves in a controlled environment, using distilled water to wash the soil through the mesh. The performance was impressive, even with relatively silty and thick mud. The water flowed through efficiently, and the 90 µm (0.0035″) sieve opening did an excellent job of retaining the finer particles.

Using the sieves was surprisingly easy. The 4-inch depth provided plenty of room to work without overflowing, and the heavy-duty frame offered a secure grip. There were no surprises other than a slight learning curve in getting the water flow just right to maximize efficiency.

Extended Use & Reliability

After several weeks of regular use, the VWR Deep Frame Washing Sieves have held up remarkably well. I’ve used them to process dozens of soil and sediment samples. Also I used them to filter out saw dust while making some wooden knife handles in the shop.

There are no signs of significant wear and tear. The brass frame remains sturdy, and the stainless steel wire cloth is still taut and free of damage. I meticulously clean the sieves after each use with a soft brush and mild detergent to prevent clogging and corrosion. This is imperative for longevity.

Compared to my previous experiences with cheaper sieves, the VWR Deep Frame Washing Sieves are in a different league. The previous sieves would have buckled under the weight of the samples I process, and the screens would have torn within a few weeks. The VWR sieve has demonstrated far superior durability and reliability. It definitely outperforms anything I have used before.

Breaking Down the Features of VWR Deep Frame Washing Sieves 170BS8W4W/SU 4″ Depth Sieves With #20 Support Cloth

Specifications

• Product Name: VWR Deep Frame Washing Sieves 170BS8W4W/SU 4″ Depth Sieves With #20 Support Cloth.
• Manufacturer: VWR.
• USA Series: #170. This indicates the sieve’s compliance with USA standards, which often relate to mesh size and frame construction.
• Sieve Opening: 90 µm (0.0035″). This is the critical specification defining the size of particles that the sieve will retain. 90 µm is suitable for separating very fine materials.
• Frame Material: Heavyweight seamless brass. Brass provides excellent durability and corrosion resistance, crucial for wet washing applications.
• Screen Material: Stainless steel wire cloth with #20 support cloth. Stainless steel is extremely durable and resistant to corrosion. The #20 support cloth likely provides additional strength and prevents the finer mesh from stretching or tearing.
• Depth: 4″ (10.2cm). This depth is ideal for containing a reasonable amount of sample and wash water without overflowing.
• Diameter: 8″ (20.3cm). This standard diameter ensures compatibility with conventional pans and covers.

These specifications are essential for several reasons. The 90 µm sieve opening dictates the type of materials I can effectively separate. The brass frame and stainless steel screen guarantee longevity and resistance to the harsh conditions often encountered in field research. The 4-inch depth allows for efficient washing without losing valuable sample material.

Performance & Functionality

The VWR Deep Frame Washing Sieves perform their primary function – particle separation – exceptionally well. The 90 µm mesh is accurate and consistent. It separates fine particles from coarser materials with minimal loss of sample. The flow rate through the mesh is optimal, allowing for efficient washing.

The sieve’s strength is its durability and precision. The only area for potential improvement might be adding a rubber gasket around the frame to create a tighter seal with pans and covers. This would minimize any potential leakage, especially when dealing with very fine suspensions.

The VWR Deep Frame Washing Sieves have exceeded my expectations. I needed a reliable and durable sieve for fine particle separation, and this product delivers on both fronts. The manufacturer‘s attention to detail is evident in the quality of materials and construction.

Design & Ergonomics

The build quality is top-notch. The brass frame is robust and the stainless steel screen is securely attached. The weight feels substantial without being unwieldy. The 4-inch depth offers comfortable working height.

There’s minimal learning curve. It is designed for straightforward use. The only consideration is getting the water flow rate right to avoid overwhelming the mesh.

Durability & Maintenance

Based on weeks of intensive use, I expect these sieves to last for years with proper care. The brass frame is resistant to corrosion, and the stainless steel screen is holding up well under constant exposure to water and abrasive particles. Regular cleaning with a soft brush and mild detergent is essential to prevent clogging and maintain optimal performance.

Accessories and Customization Options

The VWR Deep Frame Washing Sieves don’t come with a plethora of accessories, but their compatibility with standard 8″ pans and covers is a significant advantage. VWR and other brands offer a range of pans and covers designed to fit these sieves perfectly. This enables stacking and collection of different particle sizes during the washing process.

While there aren’t many “customization” options, the availability of different mesh sizes within the VWR sieve range allows users to tailor their setup to specific needs. For example, stacking sieves with progressively finer mesh sizes creates a comprehensive particle separation system. A feature that is critical for specific jobs that require strict micron filtering.
