SAFETY PRECAUTIONS

1. Although the Problot Hybridization system has been designed to minimize user expo-

sure 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. Cap seals should be replaced if they

are severely deformed or discolored. Special attention should be paid to inspecting

bottle rims / threads.

3. DO NOT take bottles to temperatures higher than 70C without opening and retight-

ening

the cap to relieve pressure build-up. Temperatures above 70C can cause breakage of

hybridization bottles. If chamber temperatures rise above 70C when bottles are in use,

DO NOT OPEN THE OVEN DOOR. Reduce the temperature setting to below 70C or

turn the power off and allow sufficient time for the bottles to cool below 70C before

opening the door.

INTRODUCTION

This manual covers the specifications, operation and use of the Labnet series of Problot Hybrid-

ization Ovens including Problot 6, Problot 12, Problot 12S and Problot 24. 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 hybridization and blot

washing activities.

Labnet’s Problot Hybridization Ovens use microprocessor controls and mechanical convection

to maintain a stable temperature environment and to achieve fast chamber temperature recov-

ery after a door opening. The oven interior is constructed from stainless steel for corrosion

resistance and the oven includes a drip pan for easy clean-up of accidental spills.

Problot rotisseries are easily removed from the oven and are adjustable for 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.

An optional rocking platform is available for each oven and the Problot Model 12S includes an

integral orbital shaking platform (10mm orbit) with optional flask platform.

Labnet Hybridization Bottles are recommended for optimum Problot Oven performance. These

bottles are made of high quality borosilicate glass, which provides a high level of protection

from the 32P beta emissions.

UNPACKING

Upon receipt of your Problot Hybridization Oven, examine the carton and unit for damages. If shipping

damage has occurred, a claim must be filed with the carrier. The carrier is responsible

for correcting shipping damages. Save all packaging until the unit has been shown to

operate properly to your satisfaction. Carefully remove the unit from the carton and ship-

ping pallet.

The package should include:

Problot Hybridization Oven Rotisserie (2 rotisseries on Problot 24 models)

4 adjustable feet Drip pan (part of shaker platform on 12S models)

Rotisserie brass locking pin 2 bottles

1 package of mesh Warranty Card and Instruction Manual

Complete and return the warranty card to register your new Problot Hybridization Oven.

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 outlet. The location selected should be out of direct sunlight and

away from heat producing sources or hot or cold air drafts. At least 5cm ventilation clear-

ance 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 for optimum leveling. Check the rotisserie and set it for horizontal or angled

use by adjusting the screws in the rotisserie hub (page 5, Setting Rotisserie Angle). Plug in

the unit to a properly rated and grounded electrical outlet and the unit will be ready for use.

STACKING PROBLOT OVENS

The Problot 6 and Problot 12 models MAY BE stacked up to two high. Problot 12S and 24

models CAN NOT be stacked. 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 Problot 12S also has controls for shaker speed and

shaking time. The controls are located at the bottom front of each oven or on the right

hand side of the Problot 24. 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. The Problot 24 has two power switches, one for each chamber.

-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 65C at the factory. The oven can be re-calibrated

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 cali-

bration 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.

-Shaker Timer (Problot 12S only) – The timer controls the power to the shaker mecha-

nism.

Turning the knob counter clockwise to the RUN position sets the shaker for continuous

operation. Turning the knob clockwise sets the shaker for timed operation in a timed cycle

from 0 to 120 minutes. The knob can be rotated counter clockwise to the 0 or RUN position

any time.

-Shaker Speed (Problot 12S only) – This knob controls the shaker speed. Turning the

knob

clockwise increases the speed from 10 to 300 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 avail-

able. Always load the rotisserie with an even number of bottles in a balanced pat-

tern.

-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. The Problot 24 has one tray for

each chamber. On the Problot 12S, the shaker platform serves as the drip tray. You may

wish to remove the rubber mat or cover the platform with aluminum foil on the 12S.

-Electrical Outlet- The 115 volt versions of the Problot 6, Problot 12 and Problot 24 mod-

els have an electrical outlet inside the chamber for small equipment such as a rocker or

shaker. This outlet is rated for 1 amp draw maximum.

SHAKER (Problot 12S only)- The Problot 12S provides an orbital shaking platform with

rubber mat. The platform can be removed by lifting up and pulling it free from the four

rubber grommets that hold the platform to the shaker mechanism. The platform is re-in-

stalled by lining up the pins on the bottom of the platform to the rubber grommet holes and

pushing downward.

An optional flask platform is available for the shaker.

ROCKING PLATFORM / INSTALLATION- An optional rocker platform is available for all

Problot 6, 12, 12S and 24 models. 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. If the rocking platform is being installed on a model Problot 12S, remove the 1”

(25mm) hexagonal arm extension using a small adjustable wrench.

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 mid-rock. If the

length of the arm is adjusted, be sure to retighten 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 chlo-

rine-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 deter-

gent such as IsoClean or CountOff and then rinsed in distilled water.
