Description
Thermo Scientific ab- ine Titer Plate Shakers are sturdy,
heavy-duty units designed to produce an accurate 0.120-
inch orbital shaking motion that is ideal for many kinds of
laboratory work with titer plates.
Controls are clearly marked, self-explanatory and make
the shaker easy to use and operate.
Users can operate the Titer Plate Shaker at a range of
speeds from 40 to 1100 rpm to produce shaking move-
ment ranging from gentle rotation to vigorous agitation to
meet specific user requirements.
For increased versatility, a rocker switch on the control
panel enables users to select either a constant shaking
motion or a timed cycle up to 5 minutes for accurate,
repetitive runs.
The ribbed platform provides a non-skid surface and
retaining springs which act to hold the titer plates securely
in place. In addition, rubber feet at the corners hold the
shaker firmly on a counter surface and prevent the shaker
from “walking.”

Shipping Carton
This should be inspected upon delivery. When received,
carefully examine for any shipping damage before
unpacking. If damage is discovered, the delivering carrier
should specify and sign for the damage on your copy of
the delivery receipt.
Open the carton carefully making certain that all parts are
accounted for before packaging materials are discarded.
After unpacking, if damage is found, promptly report it to
the carrier and request a damage inspection properly.
IMPORTANT: Failure to request an inspection of damage
within a few days after receipt of shipment absolves the
carrier from any liability for damage. You must call for a
damage inspection promptly.
eveling
Place the shaker on a level surface in a convenient loca-
tion and near a properly grounded electrical outlet that
matches the requirements of the unit as indicated on the
nameplate. A minimum of 1/2-inch clearance is required
on all sides of the unit to provide unobstructed rotation.
Electrical Requirements
• Use a properly grounded electrical outlet of cor-
rect voltage and current handling capacity.
• Do not remove or modify grounded power plug.
Use only properly grounded outlets to avoid
shock hazard.
Installation
Warning
eave the shaker disconnected
when not in use.

Controls
ocated on the front panel are easily accessible controls,
from left to right: speed control, timer and selector switch.
Speed control: rotate knob clockwise to increase shaking
speed and counterclockwise to decrease the speed.
Timer: permits setting a timed shaking period from
approximately 5 seconds to 5 minutes. Each timed cycle
is exactly repeatable until a new timed period is selected.
Selector switch: allows the operator to select either a
"Timed" cycle or a "Constant" run position. The center
position is the OFF position.
oading the Platform
Insert a filled titer plate in the spring-tensioned holder by
pushing the plate against the springs until the titer plate is
resting on the ribbed bottom of the platform and is
securely locked in position.

Operation
Warning
Do not use in the presence of
flammable or combustible materi-
als or explosive gases. Do not use
in the presence of pressurized or
sealed containers. Fire or explo-
sion may result, causing death or
severe injury.
Note
Depress metal tab prior to rotating
knob. The tab fixes knob setting and
prevents inadvertent motion of the
knob.

Caution
Before proceeding make certain
that selector switch is in the OFF
position and speed control is at the
ZERO position.

Starting/Stopping the Shaker
• For continuous shaking action, push the selector
switch to the CONSTANT position.
• In the event a timed period of shaking is
desired, push selector switch to TIMED. Next,
turn the black arrow on the timer dial to the set-
ting corresponding to desired timing period.
Press center button on timer to start the timing
period. The shaker shuts off automatically at
the end of the timed cycle. During the cycle the
white dot on the dial will rotate to indicate
elapsed time.
• During either the CONSTANT or TIMED shaking
periods, the operator can stop the shaker by
simply pushing selector switch to the center or
OFF position.
Setting the Speed Control
• After starting the shaker, turn the speed control
clockwise to the desired level of shaking action.
• It is not necessary to return the speed control to
the start or zero position after completion of
each shaking cycle. Once a satisfactory shak-
ing speed is found, the control may be left at
that setting.
• To stop the shaker, turn the switch to OFF.
• If the shaker will not be used again soon, dis-
connect the plug from its electrical outlet.
Power Mains Protection
If a fuse or circuit breaker blows, have a qualified person
replace them with a properly rated fuse or circuit breaker.
See Replacement Parts section of this manual.

OPERATION
Note
If the equipment is used in a manner
not specified by the manufacturer,
the protection provided by the equip-
ment may be impared.

Replacing Parts
Speed Control:
Replacement of the speed control requires removal of the
bottom cover casting. Turn unit over and remove 6
screws holding cover and lift off.
To replace speed control, remove the control knob (2
setscrews) and a retaining nut to separate it from the
panel. Unplug the terminal connections from the old ter-
minal unit and plug them into the new one. Reverse this
sequence to put the control unit back into position.
The new control unit must be calibrated in the following
manner. ocate the maximum and minimum speed
potentiometers on the speed control. ay the unit on its
side and elevate the housing so that the titer plate plat-
form will clear the table to permit an unobstructed area of
shaking motion.
Start the unit and turn the speed control knob fully clock-
wise (maximum speed). Using a suitable tachometer and
a small plastic screwdriver, adjust the maximum speed
potentiometer to 1100 rpm.
Next, rotate the speed control fully counterclockwise (min-
imum speed). Now adjust the "minimum" potentiometer to
the point at which platform stops moving.
If the procedure as outlined has been followed carefully,
the new speed control is now calibrated.
Replace bottom cover casting and insert and securely
tighten the 6 screws that were previously removed.
Silicone Tubing Sections:
To replace the silicone tubing sections on the platform,
remove the 4 screws holding the platform and lift off.
Silicone rubber tubing is available from most laboratory
supply houses or from Thermo Scientific. Use 1/4" ID x
7/16" OD and cut to 1-5/16" length.
Reassemble the unit carefully by following the reverse
order from the preceding.
11
Maintenance
Note
Make no attempt to service or repair
a Thermo Scientific product under
warranty before consulting your dis-
tributor. After the warranty period,
such consultation is still advised,
especially when the repair may be
technically sophisticated or difficult.
Warning
Disconnect plug from electrical out-
let before attempting any
maintenance or repair of the unit.
To avoid risk of electric shock, dis-
connect equipment from power
source before removing the bottom
cover or performing any service.
Warning
Do not operate shaker without plat-
form. To do so will produce a serious
imbalance and cause the entire unit
to walk. In addition, exposed rotating
parts will be a hazard to fingers.

Motor Brushes:
Motor brushes should be checked every three months for
wear. Turn the unit upside down and remove bottom
casting to expose the motor. 2 brushes are located under
plastic caps on opposite sides of the lower part of the
motor. Unscrew the plastic caps and slide the brushes
out. Replace brushes when they are worn down to 3/16"
in length. Always replace both brushes even if only one
brush is worn down.
