SAFETY PRECAUTIONS
1. Although the Problot Hybridization system has been designed to minimize user
exposure to radioactive materials, proper precautions must be taken when using
radioactive material.
2. Always inspect the hybridization bottles, caps and seals before use. Do not use
bottles, caps or seals that are cracked or chipped. Ca p seals should be replaced if
they are severely deformed or discolored. Special attention should be paid to
inspecting bottle r ims / threads.
3. DO NOT take bottles to temperatures higher than 70ºC without opening and
retightening
the cap to relieve pressure build-up. Temperatures above 70ºC can cause
breakage of hybridization bottles. If chamber temperatures rise above 70ºC when
bottles ar e in use , DO NOT OPEN THE OVEN DOOR. Red uce the temperature
setting to below 70ºC or turn the power off and allow sufficient time for the bottles to
cool below 70ºC before opening the door.
INTRODUC TION
This manual covers the specifications, operation and use of the Labnet series of
Problot Hybridization Ovens including Problot 6A and Problot 12A. Please pay special
attention to the Safety Precautions section in this manual.
Problot Hybridization Ovens from Labnet International provide extremely stable
temperature environments and smooth variable speed rotation that are ideal for blot
hybridiz ation and blot washing activit ies.
Labnet’s Problot Hybridization Ovens use microprocessor controls and mechanical
convection to maintain a stable temperature environment and to achieve fast chamber
temperat ure recovery after a door opening. The oven interior is c onstructed from
stainless steel for corrosion resistance. Problot rotisseries are easily removed from the
oven and are adjustable fo r either horizontal or more vigorous angled blot washing. All
oven doors have an integral glass window to allow observation of samples without
opening the door and each door is fully thermal gasketed.
The Problot 6 and 12 include a drip pan for easy clean-up of accidental spills.
Hybridization Bottles made of high quality borosilicate glass, which provides a high
level of protection from the 32P beta emissions are recommended for optimum
Problot Oven performance.

INSTALLATION
Remove the drip tray (if separate), adjustable feet and rotisserie from the chamber
(refer to page 5 for Rotisserie Removal and Installation).
Install the four adjustable feet and locate the Hybridization Oven on a stable, flat surface
near a grounded electrical ou tlet. The location select ed should be out of direct sunlight
and away from heat producing sources or hot or c old air drafts. At least 5cm ventilation
clearance is required around all sides of the oven. Level the incubator using the four
adjustable feet. Clockwise rotation of a foot raises the oven. You may wish to use a
level placed in the chamber fo r optimum leveling. Chec k the rotisserie and set it for
horizontal or angled use by adjusting the scre ws in the rotisserie hub (page 5, Setting
Rotisserie Angle). Plug in the unit to a properly rated and grounded electrical outlet and

Instruction Manual
STACKING PROBLOT OVENS
The Problot 6A and Problot 12A models MAY BE stacked up to two high. When
stacking, it is advisable to use either rubber furniture cups under the feet of the upper
unit or flat rubber matting at each corner of the upper unit or across the entire upper
surface. You may wish to remove the adjustable feet from the upper unit when
stacking. The adjustable feet can slide off the top of the lower unit and/or scratching
can occur if rubber cups or matting are not used.
To stack a unit, place the upper oven on top of the lower oven slightly toward the back
such that the upper oven does not prevent the lower oven door from moving freely.
CONTROLS & CALIBRATION
The controls for Problot ovens include power to the oven, temperature setting and
display and rotisserie power and speed. The controls are located at the bottom front
of each oven. A safety electrical circuit breaker is also supplied on the back of each
oven.
-Main Power Switch - This switch (illuminated green when on) turns the power to the
unit Off and On.
-Temperature Controller and Temperature Set – The controller has a 3-digit display
for displaying chamber temperature or set point information. UP and Down arrow
pads are used to change the set point and controller mode of operation. To enter the
set point mode of operation on the controller, press either the UP or DOWN arrow pad
one time. The display will start to blink, going from bright to dim. While blinking, the
display is showing the set point. To change the set point, use the UP and DOWN arrow
pads. If the arrow pads are not pressed for five (5) seconds, the display will stop
blinking and will read the chamber temperature. Allow at least one hour for the
chamber
temperature to stabilize and 24 hours for optimum stabilization.
-Calibration- The oven is calibrated at 65ºC at the factory. The oven can be recalibrated after the chamber temperature has stabilized at the set point for several
hours. Suspend a certified reference thermometer in a hybridization bottle such that it
does not touch the glass bottle sides or (less accurate) tape the reference thermometer
to the outside wall of a hybridization bottle. Mount the bottle on the rotisserie (and a
second bottle for balance) and run the unit at the desired temperature for 2 hours.
Compare the oven display to the reference thermometer. If there is an unacceptable
difference, put the controller into calibration mode by pressing both the UP and DOWN
arrow pads at the same time until the two outside decimal points begin to flash. While
the decimal points are flashing, the display can be calibrated to match the reference
thermometer by pressing the UP or DOWN arrow pads until the display reads the
correct value. Allow the incubator to stabilize again, and recalibrate if necessary.
-Heating Indicator-This indicator will illuminate green when the controller is calling for
heat from the heater. This indicator will be on continuously while the oven heats up to
the set temperature and will then cycle on and off at the set temperature.
-Rotisserie Power Switch – This switch turns on the power to the rotisserie and is
used to start and stop the rotisserie.
-Rotisserie Speed - This knob controls the rotisserie speed. Clockwise rotation
increases speed. The oven has a nominal speed range of 4 to 20 rpm.
-
OPERATING FEATURES
-Rotisserie – The rotisserie is stainless steel and has clips to hold hybridization bottles.
The standard rotisserie will hold either six or twelve large (300mm) bottles and double
the number of small (150mm) bottles. The clips may be squeezed inward to also hold
50ml tubes. Optional rotisseries that hold other styles of bottles or vertical 50ml tubes
are available. Always load the rotisserie with an even number of bottles in a
balanced pattern.
-Setting Rotisserie Offset Angle- The rotisserie can be adjusted to hold bottles either
horizontally or at a slight angle for more vigorous wetting action. To adjust the angle,
first loosen the screws on one hub then rotate the hub to create an angle offset
between the two hubs, then retighten the screws. Additional angle can be obtained by
loosening the screws and rotating the second hub in the opposite direction from the first
hub.
-Rotisserie Removal and Installation- Caution ! Rotisserie and oven sides may be
hot ! The rotisserie is held and driven by a two-prong fork drive on one side and locked
in a cradle on the other side by a brass locking pin. To remove the rotisserie, first
remove the brass locking pin, then lift the rotisserie up from the cradle while
simultaneously moving the rotisserie away from and off the two-prong fork drive.
Rotisserie installation is the reverse. Bottles may need to be removed before
attempting to remove or install the rotisserie.
-Drip Tray- Each oven comes with a removable drip tray.
-Electrical Outlet- The 115 volt versions of the Problot 6A and Problot 12A. This outlet
is rated for 1 amp draw maximum.
ROCKING PLATFORM / INSTALLATION- An optional rocker platform is available
for all Problot 6A, 12A. Before installing the rocker platform, the rotisserie must first
be removed (see page 5, Rotisserie Removal and Installation). To install the rocking
platform, first Install the fork adapter (rectangular bar with holes) on the rotisserie
drive fork by pressing the adapter over the two prongs and tighten the Allen screw in
the end of the adapter with the wrench provided. Do not over tighten.
Next, use the rotisserie speed control to bring the fork drive and adapter to a
horizontal position.
Place the Rocking Platform in the oven and connect the platform drive arm to the fork
drive adapter using the thumbscrew. Two positions are available on the adapter.
Select the position that allows the platform to sit horizontal (or close to horizontal)
when the fork drive and adapter are horizontal.
The platform drive arm can be adjusted and the second hole in the adapter used to
obtain more or less rocking angle or to achieve a perfectly horizontal platform at midrock. If the length of the arm is adjusted, be sure to re-tighten the locking nuts on the
arm. To operate the rocking platform, turn the rotisserie power switch to the ON
position and adjust the speed using the rotisserie speed knob.
CARE & MAINTENANCE
No routine maintenance is requires for the electrical or mechanical components of the
unit. The incubator exterior, interior, rotisserie and shaking or rocking platform (if
present) should be wiped down periodically with a soft damp cloth with mild soap. Do
not use chlorine-based bleach or abrasives. Any spills in the incubator and/or on the
rotisserie, shaking or rocking platforms should be cleaned up immediately (see
Decontamination). Be sure to disconnect the power cord before cleaning or
decontaminating the oven.
DECONTAMINATION
Should a spill occur in the oven, it is easily cleaned by wiping the affected area first
with a dilute detergent solution of IsoClean or CountOff. The area should then be
cleaned with distilled water. This method works on the oven interior, drip tray, shaker
or rocker platform and the rotisserie. Bottles and caps may also be soaked in a dilute
decontaminating detergent such as IsoClean or CountOff and then rinsed in distilled
water.
