Bio-Rad PDS-1000 / He™ and Hepta™ Systems - Manual (Page 21)

Three hexagonal gap adjustment tools of 1/8", 1/4", and 3/8" have been provided to repro-
ducibly set the gap distance (Figure 2.4). A 1/4" distance between the rupture disk retain-
ing cap and the macrocarrier cover lid is recommended for initial optimization
bombardments.
While holding the hexagonal gap adjustment tool against the bottom of the rupture disk
retaining cap, turn the adjustable nest until the macrocarrier cover lid touches the gap
adjustment tool. The position of the adjustable nest is fixed by tightening the set screw in
the white plastic shelf with the hex key wrench.
