Precision Electronically Adjustable Probe Stage AECH400V-EC
Product Detail
InSitu Pro™ AECH400V-EC is the precision electronically adjusted member of the probe-stage family: −190 to 400 °C at ±0.1 °C on liquid-nitrogen cooling and resistive heating (Max heating 150 °C/min · Max cooling 40 °C/min), with two electrically controlled probe holders whose position is adjusted under motorized control during the experiment — a specified displacement accuracy of 5 nm. Two gold-plated tungsten-carbide probes carry signals out on BNC ×2; the silver 23 × 23 mm stage sits in a compact vacuum chamber with reflection / transmission optics.
Key features
- Electronic probe control, 5 nm displacement accuracyElectrically controlled probe holders ×2 — the probe position is adjusted under motorized control during the experiment, with a specified displacement accuracy of 5 nm over an XYZ travel of ±6 mm.
- −190 to 400 °C, LN₂ + resistiveLiquid-nitrogen cooling and resistive heating at ±0.1 °C stability — Max heating 150 °C/min, Max cooling 40 °C/min.
- Probes ×2 on BNC ×2Two gold-plated tungsten-carbide probes with signals out on BNC ×2 to compatible electrical measurement instruments such as a source meter or digital multimeter.
- Reflection / transmission opticsReflection and transmission paths (φ2 mm light-transmitting hole) through a φ25 × 1 mm JGS2 top window (220–2500 nm), hand-removable and replaceable; window-to-stage 12.5 mm, chamber height 10.5 mm.
- Grounded or floating silver stageSilver 23 × 23 mm sample stage; the stage surface can be grounded or electrically floating, selectable to match the measurement configuration.
- Compact vacuum chamber110 × 170 × 45 mm at 1.5 kg. When configured with the optional vacuum system and operated under vacuum, it can reduce the oxidant supply — actual performance depends on the achieved pressure and test conditions (see the simulator below).

Cooling to −190 °C? Plan the run
Set the target temperature your experiment needs and press Start: three curves — LN₂, TEC, and natural cooling — race downward, and the verdict line shows which technologies arrive and when. The AECH400V-EC cools with liquid nitrogen at up to 40 °C/min toward the −190 °C floor:
Model: controller-limited linear ramps with a Newton-type exponential approach as each curve nears its technology floor — LN₂ at up to ~40 °C/min toward −190 °C, TEC at up to 30 °C/min toward −25 °C — a simplified schematic of how cooling may slow as the target temperature is approached. For the technologies compared here, TEC-based InSitu Pro™ stages are specified down to −25 °C, while the AECH400V-EC uses liquid-nitrogen cooling to reach temperatures down to −190 °C; actual cooling performance depends on heat load, stage configuration, and operating conditions. Curves are schematic family-level behaviour, not performance data for a specific stage or sample.
Heating in the vacuum chamber? See what it suppresses
When operated in air at elevated temperature, many metals and alloys may oxidize — the extent depends on material composition, surface condition, temperature, atmosphere, and exposure time. When the stage is operated under vacuum, the vacuum panel is the relevant case for a schematic comparison — select a temperature within the simulator’s 200–1000 °C range, hold for an hour, and compare the two panels:
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, which is the relevant case for the AECH400V-EC vacuum chamber (actual behavior depends on the achieved pressure). The simulator covers 200–1000 °C; only the 200–400 °C portion overlaps the AECH400V-EC operating range — settings above 400 °C do not apply to this stage. Curves are schematic, not performance data for a specific stage or sample.

FAQ
What does “electronically adjusted” mean, and how precise is it?
The two probes ride on electrically controlled probe holders: their position is adjusted under motorized control during the experiment, without manual micrometer adjustment, over an XYZ travel of ±6 mm, with a specified displacement accuracy of 5 nm. By adjusting the probe position, the probe tips can be brought into precise contact with the sample surface within the travel range; electrical signals then run through the probes, signal wires and interfaces to external measuring instruments such as a source meter or digital multimeter.
How is this different from the manually adjusted AECH400V-EM / EB?
Same liquid-nitrogen temperature class (−190 to 400 °C at ±0.1 °C, 150 / 40 °C/min), but a different probe and chamber design: the EM/EB carry four coaxial probes on triaxial BNC ×4 with manual adjustment via micrometer heads or bellows, while the AECH400V-EC carries two probes on electrically controlled holders with a specified displacement accuracy of 5 nm, on BNC ×2, in a much more compact body (110 × 170 × 45 mm at 1.5 kg). If your workflow requires fine electronically controlled probe positioning during a run, the AECH400V-EC is designed for that use.
Can it run under vacuum, and what does that change?
The chamber row of the specification lists Vacuum. A vacuum system is a listed option rather than part of the basic configuration, and is confirmed at quotation. When the stage is operated under vacuum, the oxidant supply can be reduced; actual behavior depends on the achieved pressure, residual atmosphere, sample material, temperature, and exposure time — the simulator above shows the comparison schematically.
What does the transmission path add?
The optical path is specified as reflection / transmission with a φ2 mm light-transmitting hole, under a φ25 × 1 mm JGS2 top window (220–2500 nm, hand-removable and replaceable). The window-to-stage distance is 12.5 mm and the chamber height is 10.5 mm — the exact optical arrangement for your microscope or spectrometer is confirmed at quotation.
How do I order, and is software integration supported?
The stage is supplied by quotation: request via this page or the InSitu Pro™ Stage Selector, and our engineers confirm the configuration for your instruments and reply with pricing and lead time. Multi-language SDKs (e.g., LabVIEW, C#) are available to enable efficient and customized system integration.
