CUSTOM ITEM: Septa, 13mm, PTFE Disc for use in 13-425mm thread, 15x45mm autosampler vial caps. Caps sold separately. MICROSOLV Brand. BULK PRICING.
Additional Info:
PTFE‑only septa are selected when maximum chemical inertness is required and elastomeric materials such as silicone cannot be used in the analysis.
The 9504S‑05‑PTFE septa discs are made entirely of PTFE, providing a clean, non‑reactive surface that minimizes interaction with sensitive samples. Because PTFE does not have elastic memory, these septa are best suited for single injections or for use with non‑volatile samples where resealing is not required.
Designed for use in 13 mm caps for 13‑425 thread, 15 × 45 mm (4 mL) autosampler vials, these discs are commonly used when converting vial caps for storage or specialized analytical applications requiring low extractables.
