The BR sample was placed on a double-sided graphite tape and was then coated with a thin layer of gold (1 mm) using an ionizing machine (Denton Vacuum LLC, Moorestown, NJ, USA) at a pressure of 20 millitorr and a current of 20 mA for 4 min.
The included Model 300 natural lubrication oil vacuum pumps are rated to achieve 20 millitorr (0.026 mbar), with a pump speed of 6.8 cfm (9.7 m3/h).
The results showed that the freeze-dried pink salmon cubes can be produced using processing parameters that include a condenser temperature of -55 C; a shelf temperature of 25 C; chamber pressure of 40 milliTorr; and freeze-dried conditions of 9.5 hours.
However, it was noted that the smaller diameter of the glass bubbles, less than 10 microns, resulted in a higher residual pressure of approximately 100 millitorr compared to the 30 millitorr pressure in the aerogel bead tests.
The IR power is preferentially coupled into the deuterium molecules and low-pressure (hundred's of millitorr) helium is used to conduct heat from the capsule to the layering sphere (maintained at ~16 K).
In other experiments, the researchers used a vacuum chamber at NASA's Goddard Space Flight Center to expose cells of Halobacterium to a space- like vacuum (1 millitorr).
