Auto Saturator, AST-600, is a computer controlled saturator for unattended saturation
of multiple plug samples or full diameter samples up to 12 inches in length. An
onboard vacuum system allows for programmed vacuum, fill with pressurization and
de-pressurization cycles. Short and long cycle vacuum cycles of 4 or 12 hours are
available, dependent upon the samples average expected permeability with pneumatic
metering valves allowing control of build up and bleed down rates. Samples can be
pressured up to 2,000 psi (133 BAR) and maintained at this pressure independent
of temperature fluctuations.
Available accessories include plug sample trays, up to 3 of which can be accommodated
and dead volume sets. Use of sample containers is recommended to help minimize grain
loss and to insure complete saturation of samples by keeping them immersed in saturating
fluid when removing them from the Auto Saturator. Dead volume sets reduce the amount
of saturate required to fill the Auto Saturator when there are insufficient samples
to completely fill the system.
