Glass Screw Thread Vials

Glass Vials with Screw Threads

Glass Screw Thread Vials are ideal for use in manufacturing and labs because of their exceptional transparency, inertness, and durability. These properties ensure that the contents remain unaltered, preserving both quality and integrity. The continuous thread (CT) finish allows for a stronger, more consistent seal compared to other neck finishes.

Their uses span across a multitude of industries, including pharmaceuticals, cannabis, essential oils, skincare, cosmetics, solvents and more. From storing precious formulations to facilitating precise measurements, glass vials offer unmatched versatility and reliability.
