No more damaged autosampler needles or sample loss. Select from polypropylene (PP), polyethylene (PE) or magnetic silver caps with various septum materials. Caps are available in different sizes, colours, septum materials, and open or closed configurations to suit your application. UltraBond cap and septum form a one-piece unit with a bonding process without adhesives for contamination-free results. Pre-slit septa prevent a vacuum forming inside the vial.
- Ensure septa is not deformed due to overtightening and extend the life of your needle
- Prevent sample evaporation due to poor vial-septa-cap sealing
- UltraClean™ high-purity septa are optimized for GC and headspace analysis
- Select caps with UltraBond® septum to avoid sample contamination
