5mm 100µL Clear Glass Polyspring Bottom | SKU: 401BS-530

This 5mm 100µL clear glass insert with polyspring bottom is engineered for reliable sample recovery in autosampler applications. The integrated polymer spring base ensures consistent vial positioning and prevents needle damage during automated sampling, making it ideal for HPLC, GC, and other chromatography workflows where limited sample volumes require maximum extraction efficiency.

• Volume capacity: 100µL for micro-volume sample analysis
• 5mm outer diameter fits standard autosampler vials
• Clear borosilicate glass construction for excellent chemical resistance and sample visibility
• Polyspring bottom design provides consistent insert positioning and protects autosampler needles
• Conical bottom geometry maximizes sample recovery from limited volumes
• Compatible with most major autosampler systems and standard crimp, snap, or screw-top vials
