Cleaning the sieve is a breeze; a simple rinse with water and a soft brush is usually sufficient. For more stubborn residues, a mild detergent can be used without fear of damaging the stainless steel. Its ease of maintenance is a definite plus.
Compared to my previous experiences with less durable sieves, the VWR Test Sieve St Steel #120 120SS12F is a clear winner. It consistently outperforms and outlasts cheaper alternatives, providing a superior level of accuracy and reliability. This is a worthwhile investment for any serious lab.
Breaking Down the Features of VWR Test Sieve St Steel #120 120SS12F
Specifications
The VWR Test Sieve St Steel #120 120SS12F boasts several key specifications that contribute to its superior performance. It features a stainless steel frame and wire cloth. The #120 mesh signifies 120 openings per linear inch, corresponding to a particle size of 125 microns (0.0041 inches).
The 12-inch diameter provides a generous surface area for efficient sieving of larger sample volumes. Its “full height” design with a 2-inch depth ensures adequate containment of the material being sieved. Each sieve has a fillet solder bead between the frame and the wire cloth.
The specifications matter because they directly impact the sieve’s accuracy, efficiency, and durability. Stainless steel ensures resistance to corrosion and chemical attack, crucial for handling various materials. The mesh size determines the precision of the particle separation, while the diameter and height influence the volume of material that can be processed at once. These features guarantee reliability.
