AT-Closed Vial®

"Item-level isolator"

AT-Closed Vial®  ensures better sterility assurance, lower particle presence and uncompromised container closure integrity, even during cryogenic storage.

AT-Closed Vials® are presently available in 6 formats, ranging from 1 ml to 50 ml, crystal clear or amber. Snap-fit caps are available in different colors.


Cyclyc olefin co-polymer (COC) for the body, known for shock-resistance, barrier properties and transparency;
Thermoplastic elastomer (TPE) for the stopper, a proprietary material allowing specific processing;
both having excellent leachables profile.


AT-Closed Vials® are provided to users ready-to-fill:
> clean,
> closed,
> sterille (gamma-irradiated).


The fully automated vial manufacturing process ensures clean conditions: vial and stopper are molded in Grade A/ISO 5 and immediately assembled by robots, minimizing particle content compared to other types of primary containers.
AT-Closed Vials® are then packed and sterilized by gamma irradiation, being supplied as Ready-to-Fill containers.
