Instrument Overview
The Automated Thermal Block is a Peltier-driven heating and cooling device pre-programmed to
perform the lysis steps of the BAX System protocols. It has been designed as a solid-state device
with minimal moving parts to help ensure quality performance over time. The temperature of the
plate is sensed by a platinum resistance temperature device mounted under the plate. The
computer in the unit compares the plate temperature with the target temperature and instructs the
module to heat or chill the plate as required.
The block automatically provides the sequential heating and cooling conditions for lysis protocols,
eliminating the need to transfer samples between separate heating and cooling blocks. Once the
lysis program is complete, the block holds the samples at 4 °C until they are removed.
This model has been optimized for use with the cluster tubes and metal tube holder supplied with
the BAX System. Other tubes and holders are not recommended.
Supplied Components
The purchase of the thermal block includes the following components:
1. Thermal block unit
2. Metal tube holders (2)
3. Power supply and cord
4. User documentation

General Safety Information
Extreme Temperatures
The thermal block is capable of reaching 110 ºC (230 ºF), which can burn
the skin if touched.
To prevent injury, remember the following:
•Use extreme caution around the block at all times.
•Never leave the block accessible to others when it is hot.
•Do not touch the plate surface unless you are sure it has cooled.
•Always keep the lid in place when the block is not in use.
Power Requirements

Connecting the Thermal Block
The Automated Thermal Block is pre-programmed to perform the sequential heating and cooling
steps needed for BAX System assays. No calibration or software installation is required when the
thermal block is used as specified.
Follow these steps to connect the thermal block:
1. Place the thermal block unit on a level, dry laboratory workbench. Allow at least 4 inches
(10 cm) on all sides of the unit for ventilation.
2. Insert one end of the provided power cord into the power supply and plug the other end
of the power cord into a 3-wire outlet.
Note: Ensure the outlet is properly grounded and runs the appropriate voltage (see specifications
on the previous page).
3. Insert the power supply jack into the power input port on the back panel of the thermal
block.
4. Seat the metal tube holder over the metal plate surface on the top of the thermal block
unit.

4 Automated Thermal Block
Front Panel Display
The front panel of the Automated Thermal Block contains the following items:
1. LCD display – shows the program menu, program selection, settings and instructions.
2. SCROLL button – changes the selected menu item in the LCD display. An audible beep
sounds when the button is pressed.
3. SELECT/CONTINUE button – sets the menu item in the LCD display as the selected
program and is also used to confirm required actions. An audible beep sounds when the
button is pressed.
4. Blue ACTION NEEDED LED – indicates that the user must perform an action before the
program can continue. This notification is accompanied by an audible alarm.
5. Green POWER LED – indicates that the thermal block is turned on.

Program Menu
The Automated Thermal Block is pre-programmed with four lysis protocols:
Gram positive – use with Gram-positive bacteria, including Staphylococcus and Listeria*
*Note: For Listeria 24E assays, use the “24E” program. For real-time Listeria assays, use the “RT Listeria” program.
Gram negative – use with Gram-negative bacteria, including Salmonella, E. coli,
Campylobacter, Vibrio and Cronobacter
24E – use with BAX System 24E assays for Listeria and L. monocytogenes
RT Listeria – use with BAX System real-time assays for Listeria and L. monocytogenes
Turning the Thermal Block On and Off
ON Turn on the thermal block by toggling
the on/off switch on the back panel of
the unit.
At start-up, the LCD automatically
displays the following series of
messages:
The first screen shows the version of
software currently installed on the
thermal block.
The second screen shows the seq file
version number and the checksum
number for validation purposes.
Note: A change in either of these values
indicates a modification to the thermal
block software. If this occurs, any
validation previously performed on the
instrument may no longer apply.
The start-up sequence is complete
when the LCD display shows the
program menu.
OFF After finishing a run, you can either
select another program or turn off the
power to the unit by toggling the on/off
switch on the back panel of the unit.

Cleaning and Decontaminating the Thermal Block
Cleaning the Thermal Block
•Do not attempt to clean the thermal block or metal tube holder when they are hot.
•Remove dust and debris by wiping the instrument surfaces with a lint-free cloth.
•Wipe all spills or condensation with a soft cloth or paper towel, if needed.
•If needed, the casing can be wiped off with a damp cloth using mild soap or detergent.
•Do not use solvents or cleansers containing iodine or acetone, as these solutions could
damage the paint or display window of the block.
Decontaminating the Thermal Block
If contamination should occur, the following steps can be performed under sterile conditions to
help remove the contaminants.
•Wipe the surface of the thermal block unit with a cloth dampened with 20% bleach
solution*, followed by a 70% ethanol rinse to prevent damage to the equipment.
•Soak metal tube holders in 20% bleach solution* for about 5 minutes, then rinse
thoroughly with water and allow to air dry.
* An alternate cleaner designed to remove free DNA may also be investigated. A 10% bleach solution may also be used
for decontamination in accordance with your laboratory SOP but may require repetition of the cleaning to ensure the
removal of all amplicons.
Calibrating the Thermal Block
The Automated Thermal Block should not require calibration when used as directed. If your
laboratory requires calibration as part of your standard operating procedures, you can use the
following procedure to calibrate the block to the nearest degree.
Materials
•Resistance Temperature Detector (RTD) thermometer with microprobe - VWR #61220-
601 or equivalent
•Cluster tubes used for lysis (at least 48)
Note: If an RTD thermometer is not available, a dry bath alcohol thermometer (VWR #89095-782 or
equivalent) may be used to perform the calibration. However, because results may be less accurate due to

User Guide 17
www.hygiena.com INS2051 Rev A
the lower resolution of the dry bath thermometer, calibration with an RTD thermometer is strongly
recommended.
The buttons on the front panel display will serve different purposes during calibration:
•SCROLL button – increases the value entered in the LCD display.
•SELECT/CONTINUE button – decreases the value entered in the LCD display.
•Pressing SCROLL and SELECT/CONTINUE buttons at the same time - sets the value in
the LCD display as the selected value.
1 Arrange 48 cluster tubes in a rack and
fill each tube with 200 µL of water.
2 Poke a small hole in the cap of one
cluster tube near the center of the
cluster tube rack.
3 With the power turned off, place the
rack of cluster tubes in the metal
holder.
