After several weeks of continuous use, the VWR Testing Sieves, All Stainless Steel 12SS8H Half Height has performed admirably. It has maintained its structural integrity and accuracy. There are no signs of wear or deformation, despite the demanding nature of aggregate testing.
Cleaning remains straightforward. A quick brush and occasional ultrasonic cleaning are all it takes to maintain optimal performance. Compared to previous brass sieves, which required constant monitoring and frequent replacement, the VWR Testing Sieves, All Stainless Steel 12SS8H Half Height is a substantial upgrade. Its durability and consistent performance have exceeded my expectations.
Breaking Down the Features of VWR Testing Sieves, All Stainless Steel 12SS8H Half Height
Specifications
- Material: All Stainless Steel. This ensures superior corrosion resistance and eliminates the risk of metallic contamination of samples.
- Sieve Opening: 1.70 mm (0.0669″). The #12 USA series designation means this sieve has a specific opening size for classifying particles around that dimension.
- Diameter: 20.3cm (8″). The standard 8-inch diameter allows for compatibility with most sieve shakers and testing setups.
- Height: Half Height (2.54cm (1″) depth to wire). The half-height design is beneficial when dealing with smaller sample volumes or when stacking multiple sieves in a shaker.
- Compliance: ASTM E-11 and ISO specifications. The certificate of compliance ensures the sieve meets stringent quality standards.
- Unique Identifier: Traceable serial number. This allows for tracking and verification of the sieve’s calibration history.
These specifications are important because they directly influence the accuracy, reliability, and longevity of the sieve. The all-stainless steel construction ensures that the sieve will not corrode or contaminate the sample, while the precise sieve opening allows for accurate particle size classification. The compliance with ASTM E-11 and ISO specifications guarantees that the sieve meets the required standards for quality and performance.
Performance & Functionality
The VWR Testing Sieves, All Stainless Steel 12SS8H Half Height performs its job exceptionally well. It provides accurate and consistent particle size separation. Its all-stainless steel construction ensures that the sample is not contaminated.
One significant strength is the sturdy construction and tight mesh. This minimizes the chance of particles bypassing the sieve or becoming trapped. A potential weakness, inherent in all sieves, is the possibility of blinding (mesh blockage) with certain types of materials; however, this is manageable with proper cleaning techniques. Overall, the VWR Testing Sieves, All Stainless Steel 12SS8H Half Height meets and exceeds expectations for particle size analysis.
Design & Ergonomics
The VWR Testing Sieves, All Stainless Steel 12SS8H Half Height features a robust and well-thought-out design. The all-stainless steel construction feels solid and durable. The half-height design is convenient for handling and stacking, making it easy to integrate into various testing setups.
The sieve is user-friendly, requiring no special training or expertise to operate. The smooth, burr-free edges ensure safe handling.
