Electrical Heating and Cooling Stage AECH600S/AECH400SV
Product Detail
InSitu Pro™ AECH600S and AECH400SV bring liquid-nitrogen cooling and resistive heating to electrical characterization: −190 to 600 °C on the AECH600S (atmosphere chamber) or −190 to 400 °C on the AECH400SV (vacuum chamber), holding ±0.1 °C. Four magnetic-mount probe holders with gold-plated tungsten-carbide probes on BNC ×4 can be repositioned by hand on the silver 23 × 23 mm stage — grounded or electrically floating.


Key features
- −190 to 600 / 400 °C, LN₂ + resistiveMax heating 150 °C/min and Max cooling 40 °C/min at ±0.1 °C stability, with fixed-point holds, ramp-rate control, and multi-segment programmable profiles.
- Four freely repositionable magnetic probesMagnetic-mount probe holders ×4 reposition freely by hand to selected contact points on the sample surface; signals route through BNC ×4 to compatible electrical measurement instruments.
- Grounded or floating stage potentialThe silver 23 × 23 mm stage surface can be grounded or electrically floating, selectable to match the measurement configuration.
- Reflection or transmission opticsReflection or transmission — the transmission path uses the φ2 mm light hole and the optional φ10 × 1 mm bottom window; φ25 × 1 mm JGS2 top window (220–2500 nm), hand-removable.
- Screw-on cover, frost-managed windowThe screw-on top cover makes sample loading and removal quick; an air-blow bracket uses LN₂ boil-off gas to defrost the window at low temperature.
- AECH400SV: the vacuum optionThe SV pairs the same probe deck with a vacuum chamber; operated with the optional vacuum system, it can reduce the oxidant supply during measurements (see the simulator below). Dimensions exclude the bellows.
- Software, SDKs & quote-ready orderingHost-computer software handles temperature setting and data acquisition; LabVIEW and C# SDKs support customized integration. Request pricing via this page or the Stage Selector.

Heating in air? Plan for oxidation
Toward the top of the range, many metals and alloys oxidize measurably in air well below 600 °C. Under diffusion-controlled conditions, oxide growth is often approximated by parabolic kinetics; actual behavior depends on material composition, surface condition, temperature, atmosphere, and exposure time. Operated with the optional vacuum system, the AECH400SV's vacuum chamber can reduce the oxidant supply — actual performance depends on the achieved pressure and test conditions. Hold a sample for an hour at a working temperature and see:
Model: parabolic oxidation x² = k·t with an Arrhenius rate constant — an approximation for diffusion-controlled oxidation, not every material or temperature; the vacuum panel suppresses the oxidant supply. AECH600S is specified with an atmosphere chamber, the AECH400SV with a vacuum chamber (vacuum system optional) — confirm the intended operating atmosphere at quotation. Curves are schematic, not performance data for a specific stage or sample.

FAQ
AECH600S or AECH400SV — which one?
The AECH600S reaches 600 °C in an atmosphere chamber; the AECH400SV trades 200 °C of ceiling for a vacuum chamber — often preferred for oxidation-sensitive samples and measurements when configured for vacuum operation (see the simulator above). Probe deck, optics, stage, and controller set are otherwise the same; SV dimensions exclude the bellows.
How do the probes work?
Four magnetic-mount probe holders sit in the chamber and reposition freely by hand, so the gold-plated tungsten-carbide tips reach selected contact points on the sample surface. Signals route through BNC ×4 to compatible electrical measurement instruments; custom probes and probe interfaces are available as options.
What does “grounded / electrically floating” mean?
The stage surface potential is selectable: tied to ground, or isolated (floating). Which you use depends on your measurement configuration — both are standard on these stages, so the choice stays with the experiment rather than the hardware.
Will the window frost over below 0 °C?
Frost is managed by design: an air-blow bracket is included, and LN₂ boil-off gas is used to defrost the window at low temperature, helping reduce frost and maintain optical access at low temperature.
