IsoTherm Benchtop Cooler
The Eppendorf IsoTherm Systems are designed to cool samples effectively and consistently over many hours at 0°C or at –21°C. The White IsoTherm System is designed for 0°C and the Blue IsoTherm System is designed for –21°C. The Systems consist of the following components: the IsoPack (cold pack), the IsoRack (transparent storage rack), and the IsoSafe (insulated transport box).
|How long do IsoPacks maintain their temperature?|
White IsoTherm System: IsoPacks that are seated in IsoRacks and sealed in the insulating IsoSafe can maintain a temperature of 0°C up to six hours. If the IsoPacks are contained in an opened IsoSafe, then a temperature of 0°C can be maintained for approximately 4 hours. If IsoPacks/IsoRacks are not placed in an IsoSafe, then 0°C can be maintained for 1.5 to 3 hours. Blue IsoTherm System: IsoPacks that are seated in IsoRacks and sealed in the insulating IsoSafe can maintain a temperature of –21°C for over 3 hours. If the IsoPacks are contained in an opened IsoSafe, then a temperature of –21°C can be maintained for 1 to 2 hours. If IsoPacks/IsoRacks are not placed in an IsoSafe, then –21°C can be maintained for 0.5 to 1 hour.
|At what temperatures can the IsoTherm Rack be stored?|
The IsoTherm Rack can be stored at temperatures as low as –200°C.
|What are IsoRacks made of?|
IsoRacks are made of polyethylene and filled with a non-toxic liquid.
|What are the IsoPack’s dimensions? What are the IsoRack’s dimensions?|
|Description||Dimensions (W x D x H)|
|IsoPack for 0.5 ml tubes||4.7 x 3.0 x 0.9 in./12 x 7.7 x 2.3 cm|
|IsoRack for 0.5 ml tubes, with lid||5.0 x 3.4 x 1.9 in./12.7 x 8.6 x 4.9 cm|
|IsoPack for 1.5/2.0 ml tubes||4.8 x 3.1 x 1.5 in./12.2 x 8 x 3.9 cm|
|IsoRack for 1.5 and 2.0 ml tubes, with lid||5.0 x 3.4 x 2.5 in./12.7 x 8.6 x 6.4 cm|
|Are IsoPacks resistant to sodium hypochloride (NaOCl)?|
Sodium Hypochloride (NaOCl) will attack the aluminum foil on both the blue and the white IsoPacks to some extent. Over a period of eight hours or more, this may lead to damage. The IsoPack’s polyethylene housing is chemically resistant to NaOCl. Even if a leak occurs, the liquid in the IsoPack is non-toxic.

|Why can’t I set the temperature higher than 70°C with the block for microplates (Brinkmann Catalog # 022670565)?|
Many microplates are made of polystyrene, which becomes soft at 80°C. As a safety precaution, the Eppendorf Thermomixer R will not exceed temperatures of 70°C when using the block for microplates. If you are using polypropylene or Teflon® plates that are rated to 99°C, you may disable this safety feature.
To avoid risk of personal injury and damage to the Thermomixer, please be sure that when disabling this feature, only microplates and deep-well plates rated to 99°C are incubated.
In order to disable this safety feature, you must deactivate the block recognition system. Please follow the procedure outlined below.
- Turn power on and set the speed to 500 rpm
- Turn the power off
- Turn the power on while holding the Temperature down arrow key; the display will indicate “service ON”
- Scroll through the menu by pressing the Temperature up arrow key until the display indicates “Block ID”
- To turn the block recognition off press the Mix up arrow key. To turn the block recognition on, press the Start/Stop button.
|Do I need to fill the thermal block holes with water?|
No. Eppendorf Thermomixer R takes advantage of Peltier technology, therefore cooling or heating fluid is not necessary. Filling the thermal block with water will damage the Thermomixer.
|I have an older Eppendorf Thermomixer Model 5436. Can I use the Model 5436 thermal block with the Thermomixer R?|
No. The model 5436 thermal block is not compatible with the Thermomixer R.
|I need to cool my samples to 4°C. Can I run the Thermomixer R in a cold room to maintain 4°C?|
Yes and no. The Eppendorf Thermomixer can be operated in a cold room, however, precise temperature control at 4°C is not guaranteed.
