1.3 Safety
Power to the Sequencing unit must be supplied by an external DC voltage power supply that must
be ground isolated so that the DC voltage output floats with respect to ground.
Current to the unit, provided from the external power supply, must enter the unit through the lid
assembly, providing a safety interlock to the user. Current to the unit is broken when the lid is
removed. Do not attempt to use the unit without the safety lid, and always turn the power
supply off before removing the lid, or when working with the unit in any way. Follow
safety precautions specified by the power supply manufacturer.

Assembly
3.1 Unit Assembly for Single Dedicated Height Sequencer
Place the Sequencer in a laboratory workspace for authorized personnel only. For protection
against possible damage, the aluminum plate and upper and lower reservoirs are shipped
detached from the unit. Do not attach reservoirs until after aluminum plate is installed. To
assemble follow steps below:
A. Aluminum plate installation (see diagram below).
1. The top-front portion of the aluminum plate will be identified. Place the aluminum
plate face down on the edge of the bench-top as illustrated below. Larger offset of
screw holes in aluminum plate should align with the top of the sequencer upright.
2. Place the four white washers on top of screw holes.
3. Place sequencer in horizontal position with base overhanging bench-top making sure
to support base of unit with one hand and line up the thumb screw holes with washer
and aluminum plate holes.
4. Support base of unit with one hand while attaching the 4 thumbscrews. Tighten
screws and return sequencer to upright position.
C.B.S. Scientific 9 Dedicated Height Sequencer
3.1 Unit Assembly for Single Dedicated Height Sequencer-continued
B. Installation of reservoirs.
1. Attach lower reservoir (with red power lead) by loosening black thumb screws on base
of unit and sliding receptacle slots on reservoir around screw stem. Hand tighten.
2. Install upper reservoir (with black lead) by detaching upper black thumb-screws and
positioning oval slot on upper reservoir so that they line up with screw holes on the
base. White O-ring should be facing forward. Re-thread black screws through base
of unit and hand tighten allowing reservoir to slide freely on sequencer upright.
The upper reservoir remains free facilitating the clamping of the glass plate assembly
to the reservoir using the bar clamp. See Section 4.1.
3. Upper and lower reservoirs are shipped with drain plugs installed. Verify that the
drain plugs are secure. If you plan to use accessory Quick-Disconnect fittings (cat.#
QDC-B and QDC-I), or ball valve, remove the drain plugs. Wrap the end of the Quick
Disconnect Insert or valve with Teflon® tape and thread into the drain hole. Be sure
the Quick Disconnect Body is secure and the Quick Disconnect Insert snaps into
place.
4. Level the assembled sequencer using the four leveling feet supplied. Each sequencer
is shipped with an attached bubble level.
3.2 Unit Assembly for Dual Dedicated Height Sequencer
Place the Sequencer in a laboratory workspace for authorized personnel only. To assemble follow
steps below:
1. Attach lower reservoirs (with red power lead) by loosening black thumb screws on
base of unit and sliding receptacle slots on reservoir around screw stem. Hand
tighten.
2. Attach upper reservoir (with black leads) by detaching upper black thumb-screws and
positioning oval receptacles on base of upper reservoir so that they line up with screw
holes. White O-ring should be facing forward. Re-thread black screws through base
of unit and hand tighten.
3. Upper and lower reservoirs are shipped with drain plugs installed. Verify that the
drain plugs are secure. If you plan to use accessory Quick-Disconnect fittings (cat.#
QDC-B and QDC-I), remove the drain plugs. Wrap the end of the Quick Disconnect
Insert with Teflon tape and thread into the drain hole. Be sure the Quick Disconnect
Body is secure and the Quick Disconnect Insert snaps into place.
4. Level the assembled sequencer using the four leveling feet supplied. Each sequencer
is shipped with an attached bubble level.
C.B.S. Scientific 10 Dedicated Height Sequencer
3.3 Glass Plate Preparation
1. Select a pair of glass plates (if using a notched set, one notched and one unnotched back
plate) for the appropriate gel height. Be sure the edges of the plates are nick or chip free.
2. It is vital that these plates are absolutely CLEAN ! Wearing gloves (and rinsing off any
residual powder), clean the glass plates thoroughly with a non abrasive detergent and a
plastic scouring pad. The cleaning solution should not leave a soap residue when rinsed
thoroughly.
3. Rinse the glass plates thoroughly with de-ionized water and wipe dry with a lint free paper
towel.
4. If desired, treat the inside (acrylamide contact) surface of one (usually the notched plate) or
both glass plates with a silanizing reagent, such as C.B.S. Scientific's Gel Repel, following
the manufacturer's instructions.
5. Immediately before assembling the glass plate 'sandwich', rinse the inside surfaces with 95%
ethanol and wipe dry with a lint-free paper towel. Avoid touching the inside surfaces with your
fingers. The wearing of gloves is highly recommended. Impeccably clean, dust-free plates
are essential for pouring gels without bubbles.
6. Assemble the glass plate sandwich in the conventional manner; place the back glass plate
inside-up on the bench, align the cleaned spacers at the sides, and place the notched plate
inside-down on the side spacers. **The use of metal “bulldog” clamps is not recommended.

3.4 Methods for sealing glass plate sandwich
(A) Gel Slider, ( B) Capillary Gel Casting or (C) Yellow tape
(A) C.B.S. Scientific's Gel Slider, Sequencing Gel Caster. This adjustable width unit
simplifies the pouring of problem-free sequencing gels for the novice or experienced
sequencer. Unit sold separately, see instructions for Gel Slider and skip section 3.5.
(B) Capillary Gel Casting. Depending upon user preference, capillary gel casting can be
performed (1) by using a bottom spacer at the bottom of the gel plate assembly, (2) by
taping the bottom section with yellow tape, or (3) by leaving the end completely open.
Assemble glass plate sandwich with side spacers on a level working surface.
1. If using a bottom spacer, offset the side spacers to accommodate the bottom
spacer, so the spacers line up with the edges of the back plate. Clamp
continuously with casting clamps (cat.# GPC-0002) as shown in illustration.
2. If using tape for the bottom section of the glass plate assembly, extend the tape
around the bottom corners in both directions to ensure an adequate seal. Apply
the tape as smoothly as possible to avoid forming air channels or bubbles along
the edges of the glass plates. Rub the tape firmly onto glass to eliminate air
channels and ensure a liquid-tight seal. Clamp the side sections of the glass plate
assembly with casting clamps (cat.# GPC-0002).

3. If leaving the bottom of the glass plate assembly open, clamp the side sections of
the glass plate assembly with casting clamps (cat.# GPC-0002).
