VARIXIO Pod Air capsules are made of clear plastic and come in individual, sterile, single-use bags, in boxes of 10 units. The capsule has a port, closed with a Luer cap, for loading the sclerosing agent and removing the sclerosant foam once formed.

Inside the capsule there is a magnetic stirrer disc, and on top of the capsule there is a removable seal that connects with the external environment for pressure equilibration prior to foam withdrawal. The capsule contains sterile air at 1 atm pressure.
