[labnetwork] N2 Pressure Builder

[Dennis Schweiger]

Travis,

Good morning.  Here at UofMichigan, we were using a pressure booster (see
attached photo) for a nano-imprinter application where we needed 1500PSI
N2.  This worked ok, and we used a cylinder as the storage tank so that we
had some volume.  However after having to rebuild this pressure builder
unit twice in the span of 12 months (bad seals), it became easier to just
use a cylinder of N2 gas, and swap the cylinders out as needed.

Haskel makes some good stuff, when I was looking to do 15,000PSI Helium
testing, but I've never actually worked with any of their equipment.

Thanks,
