What are Test Sieves Used For in the Chemical Industry?

Chemical companies must be sure that their products are free of contaminants. This requires testing using a variety of methods. Testing, in turn, requires the careful preparation of samples. Only well-collected, properly-processed samples can yield accurate results.

Test Sieves

One of the most common ways to separate particulate matter from a sample is to put the original material through a sieve. In its simplest form, test sieving reveals how much particulate matter (which is larger than the mesh size) is present in the sample. If necessary, the collected matter can then be tested to determine its composition to reveal contaminants, basic makeup, or other characteristics.

Manual or Automated Processes

When the number and size of samples are small, manual processes are usually enough to get the job done well. In those cases, handheld sieves may be used.

The commercial versions look much like old-fashioned playground sieves, but with several important differences. One is that they are made to exact size specifications, so you know exactly how large particles have to be to get caught by the mesh. Another is the materials they are made from. Our industrial sieves are “Clean by Design,” ensuring that your test results aren’t spoiled by material from the equipment itself. In most cases, ours are made of stainless steel, though brass may sometimes be used.

Sieves for use in testing machines work in the same basic way as manual ones, but they may be shaped differently. This is so they will fit the machine’s testing area properly.

Popular Sieve Variations

Stainless steel is one of the most popular materials used for sieves. That’s because stainless steel test sieves are non-reactive against most compounds. They’re also easy to clean. This makes it easy to keep a sample free of equipment-related contamination during the sample preparation and testing process.

Many companies look specifically for ASTM test sieves. These are made according to the standards set by the ASTM Committee E11 on Quality & Statistics. The standards cover aspects like non-corrosiveness, sanitation, and more. By using equipment made to set standards, testing companies can arrive at results that are immediately understandable by qualified outside personnel. Such personnel include customers, regulators, and partners. Laboratory test sieves are some of the most popular for testing, but not all companies do their testing in labs. Some tests are done in the field, especially in industries like mining, petroleum exploration, and archeology. We offer versions that are suitable for your environment, no matter how well-protected (or harsh) the location may be.
