Thermo Scientific ISA-220

Scattering Accuracy

Unlike traditional sample holders that miss scattered light, the ISA-220 captures 100% of transmitted and reflected light, ensuring precise measurements of turbid solutions, curved plastics, and translucent materials. This makes it ideal for pharmaceutical packaging, optical coatings, and irregularly shaped solids.
