Thermo Scientific™ Quartz, Fine Wool 4 µm is a high-purity amorphous silica (SiO₂) fiber supplied as fine white wool with an approximate fiber diameter of 4 micrometers. It offers excellent thermal stability, chemical inertness, and electrical insulation properties, making it ideal for high-temperature filtration, catalyst support, sample preparation, and thermal insulation in laboratory and industrial settings.

Quartz wool is widely used as a filter plug in analytical instruments, such as gas chromatography columns, and in trace metal and environmental testing where low contamination is critical.
