- Traceable to the National Physical Laboratory
- Being spherical the use of calibration samples gives extremely accurate results.
- Endecotts glass calibration samples will enable you to calibrate your test sieves to an accuracy of approximately 1 µm.
- The microspheres pass over virtually the total surface of the sieve where more apertures are examined than with any other method, making it one of the most accurate methods of sieve calibration available.
- Endecotts glass microspheres are calibrated by Whitehouse Scientific, who are recognised as one of the leading particle analysis laboratories by the BCR, and by 20 other leading European particle size analysis laboratories.
- Accurately calibrate test sieves in a matter of minutes It is as simple as 1,2,3 Select the calibration sample size that matches the aperture size of the sieve.
1. Place the 'Single Shot' sample on the sieve under test and shake for 2 minutes.
2. Weigh the sample again and calculate the percentage passing through the sieve.
3. Simply read off the percentage passing along a graph (supplied with every calibration sample) ...and the mean average aperture size in µm can be read off against the graph
*** Each individual sample is supplied with a Certifcate of Conformity***
