A seal pickup station for supplying a plurality of seals to a position where the seals may be picked up by a gas exchange head. The station comprises a supply roll of seals adhesively attached to a carrier sheet, and a pickup block having a channel through which the seals can be transported on the carrier sheet. The station further includes a sensor to detect the presence of a seal, a take-up reel to collect the carrier sheet, and a pressure roller mounted in the pickup block to maintain tension on the carrier sheet as seals are removed therefrom.

Seal pickup station

An apparatus for exchanging a first gas contained in a sealed container for a second gas. The apparatus comprises a vacuum chamber for receiving the container and for maintaining a controlled pressure about the container, a gas exchange head for exchanging gas in the container while maintaining a seal between the container and the chamber, and a vacuum source coupled to the gas exchange head and to the vacuum chamber for evacuating the first gas from the container and air from the chamber. The apparatus further has a gas source for supplying the second gas, the gas source being coupled to the gas exchange head for supplying the second gas to the container, and a sensor for monitoring the pressure in the container during gas exchange. The present invention further provides for a controller for adjusting the rate with which the first gas is removed from the container and the rate at which the chamber is evacuated such that the container is not damaged, and the controller can adjust the rate at which gas is supplied to the container and the rate with which the chamber is pressurized so as not to damage said container.
