The Atlas Orbit is available in two sizes: 6 tubes (24mm Ø, 45ml) and 12 tubes (13mm Ø, 10ml). Each tube size has a corresponding cap with septum. The novel nature of the Orbit means that as the Orbit lid is clicked in place, the inert atmosphere is applied to all the tubes. When the lid is removed, the septa are automatically re-sealed and the tubes are free to be transported.
The unique design also allows the gas and water supplies to remain connected to the reflux unit whilst the tubes are transported in the Orbit.
