Duke Standards™ 2000 系列大小均一聚合物微粒

Analyze wide size range materials through laser diffraction or other methods with Thermo Scientific™ Duke Standards™ 2000 Series Uniform Polymer Particles, NIST™ traceable polystyrene DVB particles with wider size distributions that mimic real world particles and work better on laser diffraction-type instruments. Particles meet the need for NIST traceable size standards that have slightly wider distributions than our monodisperse 3000/4000 series size standards. The wider distribution provides light scatter across a range of detectors, resulting in a more repeatable measurement.

特点：

• 这一产品材料由聚苯乙烯与二乙烯基苯交联合成，这就使微粒具有很好的耐用性与化学稳定性
• 聚合物的密度为 1.05 g/cm³，589 nm 处的折射指数为 1.59 (25°C)
• 微粒以水性悬浮体形式包装在 15 mL 尖头滴管瓶中
• 非常适合与任何需要 NIST 可追溯、且尺寸标准品标准偏差很窄的应用一起配合使用
