You could try degassing some buffer with a vaccuum, and then putting thedegassed
buffer into a bag/balloon inside your pressure vessel with the neck ofthe
bag/balloon tied to the outlet pipe of the sheath tank. This arrangementshould
prevent the sheath from saturating with gas, thereby preventingdepressurisation
bubbles. Alternatively you could try a mechanical (eg syringe) rather than an
air pump, this would probably be more expensive and intrusive(depending on what
machine you use) than the first option
