Overview
This innovative compact oven from Biocare Medical is extremely efficient and is specially designed for the rapid drying
of slides. The combination of a small footprint, turbo fan, 365-watt element and a digital programmable temperature
process controller makes this oven superior to other conventional drying ovens. This controller will autocalibrate for
the amount of mass and volume placed inside the oven, keeping the inside temperature constant and accurate. The
Desert Chamber Pro can be programmed with variable segments, times, temperatures and alarms.

Assembling the Oven
1. Position the unit in its ultimate operating location, keeping a minimum of two inches of space around the
unit and ten inches of space above the unit.
2. Place the removable drip tray on the bottom of the oven. (Figure 1)
3. Push the ends of the wire shelf brackets into the holes until the first bend is against the wall. Then rotate
the bracket down. (Figure 2)
4. Place the adjustable shelves on top of the brackets. (Figure 3)
5. Plug the Desert Chamber into a properly grounded receptacle (either 115 volt or 230 volt, depending upon
the model).
Electrical Precautions
Basic safety precautions should always be followed when using electrical equipment.
•Do not immerse cord or plug in water.
•Unplug the instrument when not in use and before cleaning.
•Do not operate the instrument with a damaged cord or plug.
•Do not let the cord hang over the edge of a table or counter or touch hot surfaces.
Important Note
The oven temperature has been calibrated at the factory and should not be adjusted by the end-user. If any
problems arise with the oven, call Biocare Medical for technical service at 800-799-9499.
Maintenance
The Desert Chamber Pro oven is designed to be virtually maintenance-free. However, the oven does require periodic
cleaning and chamber temperature accuracy verification in order to maintain operational and safety standards.
Periodically check the rear air intake vents for dirt or dust build-up. Keep the intake and exit ports clear of obstruction
and free of dust and dirt. Once a year, check the actual oven chamber temperature against a known accurate
temperature measurement device. To clean exterior and interior surfaces, use a damp cloth with an all-purpose
cleaner. Avoid commercially available oven cleaners.

Slide Drying Protocol
Drying slides correctly is essential for tissue processing.
Use distilled water only in the Water Bath. Do not use any organic or inorganic adhesion products such as gelatin. The
water bath temperature should be 10 - 12 °C lower than the paraffin melting point - usually 40 - 45 °C.
For tissue processing, use Biocare Medical Kling-On Slides or other positively charged slides for optimal tissue
adhesion. Shake the slides with a snapping action of the wrist to remove excess water that may be trapped between
the tissue section and the glass slide. Drain slides in a vertical position for 5 - 10 minutes.
Place slides in a slide rack and tap on the counter to remove residual water. Position slide rack in oven. Close oven door.
Dry slides using one of the Preset Programs.
Note: the times may vary according to the number of slides placed in the oven.
Technical Notes:
Under-fixed tissue is less likely to adhere to the slide properly. Ideally, the tissue should be grossed at 3mm, placed
in 20X volume of formalin and fixed for 16-24 hours to allow adequate infiltration prior to processing.
Do not dry tissue slides at temperatures higher than 60 - 70 °C, or for longer than one hour. Longer drying times or
higher temperatures may compromise results.
Slide Loading Guidelines
Load the oven so that air circulation within the oven is not impeded.
•Stagger slide racks on the shelves.
•Do not overload; leave a space between racks being processed.
•For the best processing performance for a single item, place it in the center of the oven.
•Do not use acids or corrosive reagents inside the oven.

1. To change from Celsius (0C) to Fahrenheit (0F) press ‘P’ button until ‘unit’ appears.
2. Press the up arrow for Fahrenheit and down arrow for Celsius. Press ‘P’ to save the change.
Setting Temperature
1. Turn on the oven by pushing the Power button. The button will light red when the unit is on.
2. Before starting a manual operation, press the ‘P’ button until ‘RUN’ is displayed and turn ‘RUN’ on by
selecting the up arrow once steps are completed.
3. To manually adjust the temperature, turn off Programs by pressing ‘P’ button until ‘PRG’ appears, then
select the down arrow to select ‘NONE’.
4. To change temperature press ‘P’ until the temperature is displayed, use the up or down arrow to select
temperature.
Note: The white LED is the actual temperature inside the oven. The blue LED is the target temperature.
Setting the Countdown Timer
The Desert Chamber Pro is packaged with a separate digital timer to track incubation time but also the oven is
equipped with a timer feature. The instructions below are provided to program time on the instrument.
1. Press and hold ‘P’until Time Start Mode appears (T.STR0 appears at the end of the timer and press down
arrow to select F. The F value allows the timer to be manually activated by pressing the F/arrow button.
Press ‘P ‘to advance to the next step.
2. Press the down arrow to select DN, for Time Countdown Direction (T.DIR) this instructs the controller to
count down. Press ‘P’ to advance or F/arrow to go back.
3. Use the up or down arrow to select unit of time, Time Base Setting, (T.TB). To select HH:MM (hours,
minutes) or MM: SS (minutes or seconds). Press ‘P’ to advance or F/arrow to go back.
4. Use the up or down arrow to select desired time, Time Interval Adjustment (T1). Press ‘P’ to advance or
F/arrow to go back.
5. Select the parameters below and press P to advance.
T1.E
Set this parameter to NO. Continue to next timer
parameter.
T. END
Set this parameter to OFF. Continue with the
next timer parameter.
T2
Set this parameter to 0000. Continue with the
next timer parameter.

6. Using the up or down arrow select what happens at the end of the timer under TRUN. ON means the
temperature controller continues to operate, OFF means end controller heating operation at the end of
the timer. Press ‘P’ once more to complete set-up and return to temperature display.
7. Once timer is set, press Start, pause, and Stop/Cancel the timer count by doing the following:
Start- Press F/arrow once
Pause- Press F/arrow once
Stop/Cancel -Press F/ arrow for 3 seconds
Stopping a Manual Run
1. Press the ‘P’ button until ‘RUN’ is displayed then use the down arrow button to select ‘OFF’.
2. Do not end a programmed run prematurely by turning off the using the On/Off button. Make sure the LED
display shows the temperatures before stopping a manual run using the On/Off button. Run Off will be
displayed until the LED displays the temperatures. This may take several minutes.
3. To turn off the oven, push the Power button.
Note: Attempting to stop a manual run using the toggle switch will result in the oven retaining the current run
settings.
If the program controls become jammed due to an electrical power surge or power outage, unplug the unit's power
cord, wait a few seconds and plug it back in to reset.
