Product Description
VialMAX™ Screw-caps for 2mL Autosampler Vials, RED, Case of 1000 (10 packs of 100)
A cap that doesn't seal right means evaporation, contamination, or a leaky vial in your autosampler tray, none of which you want to discover mid-run. VialMAX screw caps come with the septa preassembled and ready to go, so you can cap your vials and move straight to the instrument without fumbling with loose parts.
And yes, we ship these to your door with NO hidden fees. No handling fees, no "why does this cost more than the website said" moments. Just the product, free ground shipping, and a clean invoice!
