DuoVIAL’s dual-chamber products are based upon technology incorporating a unique High Recovery Vial form (HRV) + Lasered Annular Cleave Ring (LACR) modification.

LACR process

The process is carried out with a high intensity laser.

Single piece detached disk

Once cleaved, the disk is left over with no particles or sharps.

LACR Technology

Manually cleaved

The lasered surface provides a feature that can be cleaved manually to open the flow path.

Frosted surface

The cleaved surface has a soft frosted surface, like pebbles of glass on the beach.

Filling and sealing

A single piece tubular glass container, consisting of two chambers separated by an impermeable glass membrane.

Ampoule chamber, benefiting from the inertness of only glass contact, is filled with liquid diluent.

Ampoule chamber is hermetically sealed using the established flame sealing process.

Vial chamber, benefiting from the functionality of the lyo-stopper, is filled with liquid or powder.
