Instructions for use
4.2 Inserting tubes

Press the tubes lightly into the holders of the thermoblocks.
To maximize temperature control, transfer the micro test tubes in IsoRacks to the
thermoblock. The IsoRack reduces the heat exchange of the thermoblock with the
environment. If necessary close the IsoRack cover.
4.3 Using the IsoTherm system
Recommendations for precooling
•
Cool pack 0 °C: approx. 2 hours (*** freezer) or over night (* freezer)
•
Cool pack –21 °C: approx. 4 hours at –35 °C (**** freezer, setting: rapid freeze)
Operation
1. Insert precooled cool box into the insulating box.
2. Place tube holder with samples onto the cool box.
3. Close insulating box with a cover.
This prevents the formation of frost.
The samples can be temperature controlled for several hours at 0 to –21 °C.
1. Place the exchangeable thermoblock (2) on
the thermosocket with the flat edge and the
writing facing the front.
2. Tighten the captive screws (1).
CAUTION!
Caution! Damage of the IsoPack from sharp edges.
Sharp edged components can damage the film on the underside of the
IsoPack.
 Do not use sharp edged components near the IsoPack.
