DESCRIPTION
The Force Digital Bench Top Incubated Shaker combines
microprocessor- based temperature control and timing with variable shaking speed
in a controlled environment chamber. The unit is designed for growing and
maintaining cultures and microorganisms in ambient air or inert gas environments
and is ideal for cell, tissue and bacterial culture studies.
Interchangeable 18” x 18” (46 x 46m) shaking platforms are available
which can accommodate a wide range of sizes and numbers of flasks, beakers
and test tubes. These are ordered separately to meet specific requirements.
A clear plastic cover allows unobstructed viewing of samples as they are
being shaken in the incubating atmosphere. A lid switch turns off the shaker
when the cover is raised. Shaking resumes when the cover is closed.
The temperature range is from ambient +5ºC to 60ºC. To protect
against overheating, the controlling microprocessor will shut off the heaters in
the event the temperature exceeds the setpoint by 2ºC. This is supplemented by an
overt-temperature safety system consisting of an independent hydraulic
thermostat set by the user at a temperature slightly higher than the setpoint.
Heat control is PID with an RTD temperature sensor. Heated air is
circulated in the chamber by a blower positioned in the back plenum.
Shaker speed range is 15 to 500 rpm; however, maximum safe-speed for
a load may be less than 500 rpm.
Timing can be selected in intervals of 0.1 to 99.9 minutes or hours. In
addition, unit can be set for continuous operation with "time elapsed" indication.
Optional accessories include a factory installed cooling coil which
produces below-ambient temperature control in the chamber, a factory installed
gassing manifold which permits gas injection of up to a maximum of 8 vessels
and a portable light bank for studies of photosynthesis.

SAFETY THERMOSTAT:
This hydraulic thermostat is a secondary back-up system to protect
specimens from excessive heating in the unlikely event of microprocessor
failure. It should be set slightly higher than the setpoint temperature. If the
temperature should ever reach the setpoint +2ºC, a microprocessor safety will open a
relay link to the heaters and shut them off, the hi-limit legend is displayed and beeper
alarm sounds.
The hi-limit thermostat can be accessed in the lower right hand corner at
bottom front of the unit. Pry off small plastic button to gain access. Use a small
blade screwdriver to make the necessary adjustments.

supplied with a 3-wire line cord. It should be plugged into an outlet
designed for 3-prong plugs. If an extension cord is used, it also should be
the 3-wire grounded type. For an outlet designed to accept 2-prong plugs
(ungrounded), it is
required that a qualified electrician replace the outlet with a new grounded type.
240 VAC models require a 240 VAC, 50/60 Hz power source. Because of
the variety of plug configurations in use worldwide for 240 VAC power, the unit is
furnished with the plug removed. The user must install a plug to conform with
local code and configuration requirements.
100 VAC models require a 100 VAC, 50/60 Hz power source. Because of
the variety of plug configurations in use worldwide for 100 VAC power, the unit is
furnished with the plug removed. The user must install a plug to conform with
local code and configuration requirements.
If a plug must be installed, use only the 3-prong grounded type, rated for
the unit load requirements and matching the power outlet. Make sure the green
ground wire is secured to the plug ground terminal.
NOTE: LEAVE UNIT DISCONNECTED WHEN NOT IN USE.
PLATFORM INSTALLATION:
Select the platform that accommodates the vessels to be shaken. Attach
the platform on the shaking plate by inserting and tightening the 4 button-head
screws using an Allen key or knurled thumb-screws depending on platform being
used. Make sure that all 4 sides of the platform are outside the shaking plate.

"DRAIN". Run tubing from the "IN" port to the coolant circulation and from the
"OUT" port to the coolant reservoir. Condensation from the incubator chamber
will drain from the port marked "DRAIN.” Run tubing from this port to a floor
drain or container.
OPTIONAL GASSING MANIFOLD:
For older style shakers, use the following instructions:
Connect 1/4" (6.4mm) ID tubing to the gas inlet port on the right side of
the unit, near the rear. Connect the other end of the tubing to the flow regulator
on the gas tank. Use only noncorrosive, nonflammable inert gases. Connect
1/4" (6.4mm) ID tubing to eight hose barbs inside the chamber along the back.
Run the tubing into the vessels.
Gassing manifolds for new style shakers are installed as follows:
?Securely fasten the manifold to the cover with the furnished 8-32 x 5/8
tapping screws, #8 flat washers, #8 lock washers and #8-32 hex kep nuts.
?Attach flexible tubing to the barbed fitting on the manifold and, allowing
sufficient length for movement, cut and attach tubing to the gas source
regulator.
OPTIONAL LIGHT BANK:
Unpack the light bank carefully. Note that the supports and hardware
are separate from the main unit. Install the 4 supports at the corners of the

modules on the control panel will illuminate.
SPEED CONTROL:
This module provides a 3-digit readout of the speed of rotation up to a
maximum rpm of 500. Use the up and down buttons to set the desired
shaking speed.
The start button will initiate the shaking action; however, do not use
until all containers have been secured in place on the platform and have been
stoppered, if necessary. It is recommended that shaking action be started at
less than the required speed, in order to check that all containers are secure, not
contacting each other. and that no spilling of contents can occur.
If, for any reason, the unit exceeds the set speed by 125%, an overspeed
legend appears in this module and shuts the shaker down.
The speed setpoint may be altered at any time during the operation.
TIMER: The timer module allows 3 selections: (1) timing of the shaking action
up to 99.9 minutes, (2) timing of the shaking action up to 99.9 hours, or (3)
shaking operation can be selected as CONTINUOUS. Use the up and down
keys to select the set time.
Selections made will illuminate as a legend in this module.
An LED readout will show the time remaining and stop the shaker when
the set time has timed out. (Timer mode only)
The timing interval can be changed at any time during the shaking action.
For example, if the original selection is 1.5 minutes and 0.5 minutes have
elapsed when a new timing interval of 4.0 minutes is entered, the timer will
subtract the 0.5 minutes already elapsed and show 3.5 as remaining.
