Square Fused Silica Capillary Tube Packing

Square Fused Silica Capillary Tubes are packaged in protective anti-static containers with foam cushioning to limit mechanical stress. Each unit is sealed in moisture-resistant wrapping to prevent contamination during transit. The packaging ensures stable storage conditions and minimises handling damage. Custom packaging options, including labelled cartons and reinforced crates, are available for specific laboratory or industrial requirements.

Additional Information

Fused silica is an amorphous form of silicon dioxide known for its excellent thermal and electrical insulating properties. Its low coefficient of thermal expansion makes it particularly useful in applications that require temperature stability and minimal dimensional change.

Historically used in optical applications, fused silica has expanded into roles in microfluidics and precision instrumentation. Its compatibility with silicon-based manufacturing processes allows it to be integrated into systems where controlled fluid flow and heat management are critical for performance.
