From fine pharmaceutical powders to food, minerals, and chemicals, test sieves can assess particle size and be used for sifting and filtration. If you work in a laboratory, research center, or university, you may use sieves in your research or quality control processes.
Sieve Materials and Sizes
Sieves are available in various materials such as stainless steel, brass, or brass frames with stainless steel mesh. Check to see if a test sieve certificate of compliance, equivalent to ASTM E11-09 compliance, comes with your sieve.
Diameters of sieves include 3”, 8”, and 12” with mesh sizes ranging from 4 millimeters to 38 microns. When stacked on a shaker, the top sieve usually has the largest mesh size and the bottom the smallest mesh size.
Why use a sieve shaker? To achieve uniform motion that delivers reproducible results you can’t get from hand sieving. You can even standardize your procedure for reliable results. Look for shakers with amplitude control and timers.
Some sieve shakers allow you to establish the particle size for aggregates, ores, pharmaceuticals, powders, and more. If available, a touch-screen programmable controller enables selection of vibration level, time, and pauses.
Electromagnetic sieve shakers are virtually maintenance free, with no motor and no moving parts.
