TAC-60L/60i - Specs
Automatic Cooling Attachments
TAC-60L
DSC-60A + TAC-60L + Labsolutions TA PC set + FC-60A + ATG-60, etc.
The TAC-60L system uses liquid nitrogen as the catalyst for cooling samples down to -130 °C.
- Stable Baseline
The tank internal pressure is optimally controlled according the residual amount of liquid nitrogen in the tank to keep the supply flowrate constant. Pulsation is reduced, and the DSC baseline is stable even during cooling.
- Space-Saving
Installation space is saved since the liquid nitrogen supply control system is placed compactly in the pump head section.
- Refrigerant Savings
Samples can be cooled only when required since supply start/stop is controlled in steps according to a temperature program. Also, for safe operation and minimizing refrigerant consumption, refrigerant supply is automatically stopped when the measuring unit reaches a high temperature.
- Autosampler Continuous Measurement Supported
Samples can be replaced easily during cooling thanks to the unique layout at the rear of the cooling unit. Moreover, gas can be allowed to pass for a fixed period of time after measurement ends to prevent dew and frost condensation. (when the optional ATG-60 is connected)
TAC-60L Liquid Nitrogen Cooling System
| Temperature range |
-130 °C to 500 °C |
|---|---|
| Cooling program |
Start/stop of liquid nitrogen supply can be set to operate in sync with the temperature program. |
| Protective functions |
Gas flow start/stop after cooling stops (ATG-60), liquid nitrogen supply stop at high temperatures |
* Including accessory liquid nitrogen tank (35 L). The continuous operating time when this tank is used is approximately 8 hours. (This changes according to the temperature program.)
TAC-60i
DSC-60A + TAC-60i + Labsolutions TA PC set + FC-60A + cooling unit
The TAC-60i electric-cooling type attachment does not require liquid nitrogen and can cool samples to down -50 °C.
- No Catalyst Required
Liquid nitrogen or other catalysts are not used, which means that liquid nitrogen need not be prepared before measurement or that there is no worry about ventilation.
- Just Connect the Cooling Unit
Samples can be cooled down to -50 °C for measurement by simply connecting a cooling unit (intra cooler).
TAC-60i Electric-Cooling Attachment
| Temperature range |
-50 °C to 500 °C |
|---|---|
| Protective functions |
DSC heating furnace forcibly turned OFF at a cooling head temperature of 70 °C |
*To prevent condensation, be sure to use dry nitrogen or inert gas when operating this system.
Selection Between TAC-60L Liquid Nitrogen Cooling System and TAC-60i Electric-Cooling Attachment
TAC-60L: This is recommended when cooling down to -50 °C or less (possible down to -130 °C) or when mixing cooled and non-cooled measurements.
TAC-60i: This is recommended when it is difficult to obtain liquid nitrogen on a daily basis, when it is difficult to ventilate vaporized nitrogen from the test room, and when performing measurement for 8 hours or more non-stop.
