Extraction Manifold
Needle Tip
Luer Plugs:
use to seal open
needle tips
White Rubber Ball:
push it up or down slightly to
release vacuum in chamber Locking Nut:
(in center) tighten it to
secure set position of
vacuum control valve
Vacuum Control Valve:
rotate outer end to adjust
vacuum to desired level
Bleed Port Hole:
cover it with your
finger tip to increase
vacuum temporarily
To remove a cartridge from the manifold, turn it while pulling it
up. The valve or needle tip) will remain in its socket. To remove
a valve or needle tip from the cover, pry it out carefully with the
ejector tool. 5. For installed needle tips that are not in use, install the Luer
plug by pushing it down in the needle tip(s) input hold (see
Figure 7). Luer plus is used only on the needle tip. Do not
install Luer plug directly on the cover.
6. To remove any of the Luer plugs or columns, first twist the
part then pull upward (see Figures 7 and 8). Pulling is straight
upward is not recommended and can cause the needle tip to
disengage from the cover.
7. To remove needle tips and/or stopcock valves (if used), use the
ejector (see Figure 8).

Figure 5. Lightly wiggle the needle tip while pushing it down in the hold. Press
it with your thumb and then using the ejector handle push it hard against the
hole to ensure a good contact (also see Figure 5 and Step 3 on the needle tip
installation procedure).
Figure 6. Place ejector (handle position) horizontally or diagonally across two
needles and press down to ensure proper vacuum seal.
IV. needle tIP InstallatIon Procedure
Attention: To achieve proper sealing between the needle tips and the
holds on the cover, this procedure requires that the cover must be placed
on the glass chamber! Not following this requirement will result in
improper needle seating that can lead to low or lost vacuum pressure and/
or damage to the three alignment posts on the underside of the cover.
Make sure that the cover is resting on the class chamber’s edges and not
on the rack.
1. Remove the rack from inside the glass chamber. Alternatively,
with the rack inside the chamber, ensure that the cover’s 3
posts are in the correct alignment with the rack and are not
touching/resting on the rack.
2. Align and place the cover on the glass chamber, make sure it is
seating properly around the edges of the class chamber.
3. Insert a needle tip in the hold and lightly wiggle the needle
while pushing it down inside the hexagon hole until it feels that
the serrated portion of the needle body is seated against the
corners of the hexagon shaped hold on the cover (see Figure
5). Then with your thumb, push the needle as far as it can go.
Repeat the same steps, for the rest of the needle tips. The same
method is also used to install stopcock valves (if used).
4. Place the ejector handle portion, horizontally or diagonally,
on top of two needles and press it down hard. Repeat the same
steps on all the needles (see Figure 6). It is also applied toward
the installation of the stopcock valves (if used).
To Remove Columns
Empty Tube! Twist tube to break off contact, then pull upward.
Pulling directly upward without twisting is not recommended and can
casue needle tip to disengage from the cover.
Slide
Twist
and
Pull Up
Push Down Gently
To Remove any of the Needles/Stopcock Valves:
Slide ejector under the needle tip or stopcock
valve and push ejector down.
Caution: Push down gently, pushing ejector down too fast or
too hard will cause the part to bounce off in the air
Place ejector (handle portion) horizontally or diagonally across
two needles and press down to assure proper vacuum seal
