ChromoSphere™ 干性染色聚合物微粒

Achieve high visual contrast with Thermo Scientific™ ChromoSphere™ Dry Dyed Particles, polymer particles that are internally and deeply dyed in intense red or black, resulting in very high contrast and visibility relative to most background materials. Available as dry powders that can be easily suspended in aqueous media, the product line consists of a large assortment of uniform, red or black particle sizes between 50μm and 500μm.

粒子的标称直径范围为 50μm 至 500μm。微粒成分为交联聚苯乙烯二乙烯苯 (PS-DVB) 共聚物，室温保存。它们可以分散在甲醇或乙醇等低级醇中，借助于少量表面活性剂，还可以分散在水介质中。当悬浮在纯酒精中时，这些微粒几乎不会发生染料萃取。应避免使用其它有机溶剂，如醚或氯代烃，因为这些溶剂会使微粒膨胀并且完全掉色。
