Hello AMMRL colleagues,
As the helium shortage continues, we've been having trouble obtaining He
gas for pressurizing the tank during He fills. We've been told that
because our ordering history is about 1 tank every 2 months, our monthly
allocation is zero. Interestingly, we haven't had trouble getting the
liquid---as yet.
To conserve resources and circumvent the ordering problem, we want to use
a bladder instead. I recall using an orange soccer ball (football)
bladder that was rigged to fit the dewar, years ago.
Does anyone know a source for a He dewar bladder with standard fittings
supplied=3F Are any of you still (or already) using this method=3F
Thank you in advance.
With best regards,
Kelly
