FusedSilicaGlaskapsel

FusedSilicaGlaskapsel refers to a class of microscale containment devices made from fused silica, a high‑purity form of quartz glass. The term is commonly used in analytic chemistry, materials science, and pharmaceutical research to describe small, high‑temperature resistant capsules that can hold samples for analysis or synthesis. The capsules are typically cylindrical or hemispherical, with internal volumes ranging from a few microliters to several milliliters, and are fabricated from fused silica through processes such as precision machining, laser ablation, or lithographic patterning followed by a high‑temperature fusion step. Because fused silica has a very high melting point (around 1600 °C) and excellent chemical resistance, these capsules can endure harsh environments that would degrade ordinary glass, plastics or polymer containers.

Applications of FusedSilicaGlaskapsel include high‑pressure high‑temperature (HPHT) reaction vessels in materials synthesis, microreactors for studying chemical kinetics, and sample holders for spectroscopic techniques such as Raman or Fourier‑transform infrared (FT‑IR) spectroscopy. In bioanalytical contexts, these capsules protect sensitive biomolecules while allowing precise temperature control. The optical transparency of fused silica also permits optical interrogation without interruption from container walls, making it ideal for photochemical or flow‑based assays. Manufacturing tolerances of better than 10 µm and surface roughness on the order of a few nanometers ensure reproducible fluid dynamics and minimal adsorption of organic compounds. Because of these combined mechanical, thermal, and optical properties, fused silica glass capsules remain a critical component in advanced laboratory workflows where sample purity and environmental stability are paramount.
