Sieve Calibration Beads: NIST Glass Beads for Sieves, #10 to #20

NIST Glass Beads for Sieves, #10 to #20 are calibrated glass beads to determine effective sieve opening with precise measurement of microspheres and their corresponding sizes in diameters. These beads are used to measure effective sieve openings during testing. These calibrated items are required to determine effective sieve openings. The method of calibration with NIST Glass Beads is accurate and reliable. Microspheres are used for precise and economical calibration of sieves. The count of openings examined during calibration is critical.

Sieve opening size and tolerance are measured through these methods. NIST Glass Beads is a quick and economical way to calibrate sieves. NIST Glass Beads can test particle size analysis intervals across various sizes. NIST Glass Beads is a Standard Reference Material issued by NIST. They are best used with smaller aperture sieves for accurate calibration results Some calibration methods can do without special equipment. You need to use sieves that meet recognized ASTM mesh standards or ISO mesh standards. Calibration is traceable to recognized standards from accredited organizations like NIST. Bead sizes go down to 20 µm.

The entire sample is placed on clean sieves and shaken in the same way that tests will be performed on test samples. Percent of glass beads retained on each sieve is calculated and effective opening of each sieve is determined from the calibration data on the NIST Certificate supplied with the bead set.

What are NIST Certified Sieves

NIST certified sieves are used in various industries such as pharmaceuticals, food processing and materials science where precise particle size analysis is required. NIST glass beads also known as calibrated glass beads is a key component in the calibration and certification process of these sieves. These glass beads are made of soda-lime glass and is designed to effective opening of sieves to meet the specifications. The entire sample of glass beads is placed on clean sieves and shaken in the same way that tests will be performed on actual test samples. Percent of glass beads retained on each sieve is calculated and effective opening of each sieve is determined from the calibration data.

Characteristics and Applications

NIST glass beads characteristics make them perfect for sieve calibration and certification. They come in various sizes from 2450 to 100µm and are made of soda-lime glass for consistency and accuracy. The beads are used to test the opening of electroformed sieves which are commonly used in laboratory. The calibration process involves using the glass beads to determine the effective opening of each sieve and the results are used to create a calibration chart. This chart is then used to calculate the percent of glass beads retained on each sieve to ensure the sieves are accurate and reliable. NIST certified sieves are used in various applications from pharmaceuticals to food and calibrated glass beads ensures the results are accurate and consistent.
