Product Description
When a septum-style liner that reseals after piercing is useful, PTFE/silicone is a strong choice. This vial file provides 40 amber 4 mL screw thread vials with PTFE/silicone-lined caps, protecting contents from light while sealing reliably. It suits analytical labs storing solvent-based samples.
