XT Starter
XT Starter Instructions for UseInstructions for Use
Overview of XT Starter
XT Starter is a stationary device designed for maintaining sample temperatures below 4°C on the bench top
without the use of wet ice, batteries or electricity. Patent-pending dual-phase conductive XT Cooling Core
provides the cooling source when a thermo-conductive CoolRack or CoolSink tube or plate module is placed
on top. The core and sample module in combination ensure uniform well-to-well temperature throughout the
cooling period regardless of sample position. XT Starter can maintain sample temperature from 0.5 to 4oC for
over 4 hours.

XT Starter Assembly
XT Starter consists of a high-density polyethylene foam holder and a reusable XT Cooling Core. When a
CoolRack or CoolSink tube or plate module is placed on top of XT Cooling Core, the modules and samples
rapidly equilibrate to the temperature of XT Cooling Core. Samples can be placed in the CoolRack or CoolSink
module either before or after the module is placed on top of XT Starter.

Quick Start
• Remove XT Cooling Core from -20°C freezer and
place on bench
• When temperature strip on XT Cooling Core
registers 1°C, place CoolRack® or CoolSink®
sample module on top of XT Starter
• Load samples in CoolRack or CoolSink modules
Caution
• Place XT Starter with sample module in a safe
place on the benchtop to prevent accidental spills.
• Avoid touching the top metal surface of the XT
Cooling Core when removing from freezer.
• Condensation might occur during the cooling
period. Simply wipe with a lab tissue to remove.
IMPORTANT: To ensure your samples do not freeze and to get maximum cooling duration, please refer to the
detailed instructions that follow.

Actual performance may vary depending upon CoolRack module employed, sample load, initial sample temperature,
ambient temperature, air currents, and other conditions.

To Assemble:
1. Freeze XT Cooling Core in a -20˚C freezer for at least 12 hours.
XT Cooling Core should be stored in -20˚C freezer when not in
use so it is ready when needed. Note: Freezing XT Cooling Core
for less than the specified time may result in decreased cooling
duration.
2. Remove XT Cooling Core from the freezer and place on the
benchtop for approximately 10-15 minutes. When the tempera-
ture indicator displays 1oC, XT Cooling Core is ready to use.
Note: Frost will form on the core exterior upon removal from the
freezer; when the frost liquifies, the core is at proper temperature.
3. Remove any condensation with a lab tissue and place
XT Cooling Core into XT holder.
4. Place a CoolRack or CoolSink module onto XT Cooling Core.
5. Load samples.
