Breaking Down the Features of VWR Testing Sieves, 8 Brass Frame, Stainless Steel Wire Cloth 2inBS8F Full Height
Specifications
The VWR Testing Sieves, 8 Brass Frame, Stainless Steel Wire Cloth 2inBS8F Full Height features an 8-inch (20.32cm) diameter frame. This is a standard size for sieve analysis, providing a good balance between sample capacity and ease of handling.
The sieve has a 2-inch (5.08cm) full height depth to the wire. This allows for larger sample volumes and reduces the likelihood of material overflowing during shaking.
The frame is constructed of brass, known for its strength and resistance to corrosion. This ensures the sieve maintains its shape and structural integrity over time.
The wire cloth is made of stainless steel, offering excellent durability and resistance to abrasion and chemical attack. This ensures the accuracy and longevity of the sieve.
The sieve opening is 50.00 mm (2″). This specific opening size determines the particle size cut-off, crucial for accurate analysis.
It complies with ASTM E-11 and ISO specifications. This guarantees the sieve meets industry standards for accuracy and construction.
Each sieve has a traceable serial number and comes with a certificate of compliance to applicable ASTM E-11 and ISO specifications. This provides assurance of quality control and traceability.
CENTERLINE® measurement (47730-590) is a NIST traceable service that checks calibration and gives statistical measurement information on each sieve. This ensures that the sieve meets NIST standards.
These specifications matter because they directly impact the accuracy and reliability of our particle size analysis. The combination of a robust brass frame and durable stainless steel mesh ensures that the VWR Testing Sieves can withstand the rigors of daily use while maintaining their precision. The compliance with industry standards is particularly important for our quality control processes, providing confidence in the results we obtain.
