Product Description
VialMAX™ 11mm Snap Caps, Red PTFE/White silicone septa, 1000/cs
VialMAX™ 11mm Snap Caps, Red PTFE/White Silicone Septa (1000/cs)
Skip the crimping tool. VialMAX 11mm snap caps come pre-assembled with red PTFE/white silicone septa, so you press the cap on, hear the click, and you're sealed and ready to load the tray. The PTFE face gives you a chemically inert surface facing the sample, while the silicone backing keeps the septum resealing cleanly across repeated needle punctures.
No hidden fees, ever: case pricing is exactly what you see, and ground shipping out of Maryland is always free!

FAQ
What septa material is used? Red PTFE facing the sample, white silicone backing for resealing performance.
Is the septum pre-slit? SPEC NEEDED. Contact us if you need to confirm pre-slit vs. non-slit before ordering.
Will this seal a crimp-top vial? No, this is a snap-top cap. It only works with 11mm snap-ring vials, not crimp-neck vials.
Can I reuse the cap after removing it? Snap caps can be removed and reapplied, but for sample integrity we recommend a fresh cap per new sample.
What pack size is this? Case of 1000.
