Micro Glass Fiber Thimbles are precision-formed filtration components made from 100% borosilicate microglass fibers, engineered to withstand high temperatures and aggressive chemical environments. These thimbles are commonly used in Soxhlet extraction and air sampling applications where accurate retention of particulates and extracts is critical.

With their uniform structure and high thermal stability (up to 500°C), these thimbles provide efficient filtration without loss of integrity, making them ideal for gravimetric analysis, emissions testing, and environmental monitoring. They are completely binder-free, ensuring no interference with analytical results, and they maintain dimensional stability under prolonged exposure to solvents and heat.

Their cylindrical form allows easy installation into standard extraction and filtration apparatus, and they are available in various diameters and lengths to suit a wide range of setups.
