Thermo Scientific Duke Standards 2000 Series Uniform Polymers

貨號:2005A~2040A

品牌:Thermo Scientific 

產(chǎn)品介紹

Your trusted partner in particle science


These polymer spheres meet the need for NIST traceable size standards that have slightly wider distributions than our monodisperse 3000/4000 se-ries size standards. These products are suitable for laser diffraction and other methods for analyzing wide size range materials. The wider distribution

provides light scatter across a range of detectors resulting in a more repeatable measurement.


The material is composed of sulfate cross-linked with divinylbenzene. This gives the particle good durability and chemical stability.
