External Adjustable Probe Stage AEPE120V-EM
Product Detail
InSitu Pro™ AEPE120V-EM brings externally adjustable probing to the TEC (Peltier) side of the family: −25 to 120 °C at ±0.1 °C on TEC (thermoelectric) heating and cooling — no liquid-nitrogen consumption — with four gold-plated tungsten-carbide coaxial probes on triaxial BNC ×4 and an XYZ probe travel of ±6 mm. A copper 40 × 40 mm stage that can be grounded or electrically floating sits under a φ100 × 3 mm top window in a vacuum chamber.
Key features
- −25 to 120 °C on TECPeltier-effect heating and cooling at ±0.1 °C stability with a maximum heating / cooling rate of 30 °C/min — no liquid-nitrogen consumption required.
- Externally adjustable probes, XYZ ±6 mmThe probes are adjusted from outside the chamber over an XYZ travel of ±6 mm, so the probe tips can be brought into precise contact with the sample surface within the travel range.
- Coaxial probes ×4, triaxial BNCFour gold-plated tungsten-carbide coaxial probes with signals out on triaxial BNC ×4 to compatible electrical measurement instruments such as a source meter or digital multimeter.
- φ100 × 3 mm top windowLarge JGS2 quartz-glass window (220–2500 nm), hand-removable and replaceable, with a 14 mm window-to-stage distance and an 11 mm chamber height.
- Grounded or floating copper stageCopper 40 × 40 mm sample stage; the stage surface can be grounded or electrically floating, selectable to match the measurement configuration.
- Vacuum chamberRuns a vacuum chamber; when operated under vacuum, the oxidant supply can be reduced — actual behavior depends on the achieved pressure and test conditions, and the operating environment is confirmed at quotation.

Cooling below ambient without LN₂? 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 TEC curve is this stage's own technology: the AEPE120V-EM cools thermoelectrically at up to 30 °C/min toward the −25 °C floor:
Model: controller-limited linear ramps with a Newton-type exponential approach as each curve nears its technology floor — TEC at up to 30 °C/min toward −25 °C (this stage's own curve and floor), LN₂ at up to ~40 °C/min toward −190 °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 like this one are specified down to −25 °C, while LN₂-cooled family members reach −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.

FAQ
What does “externally adjustable” mean, and what does the “-EM” suffix denote?
The probe positions are adjusted from outside the chamber over the specified XYZ travel of ±6 mm. Across this family, the -EM suffix denotes models whose probes ride on built-in positioning stages adjusted via micrometer heads. By adjusting the probe position, the probe tips can be brought into precise contact with the sample surface within the XYZ 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 AEPE120 / AEPE120V?
Same TEC temperature class (−25 to 120 °C at ±0.1 °C, up to 30 °C/min), but a different probe and chamber design: the AEPE120/120V use fixed probe holders on BNC ×4 with a φ25 mm top window, while the AEPE120V-EM adds externally adjustable coaxial probes on triaxial BNC ×4 under a much larger φ100 × 3 mm window, in a vacuum chamber. If your contact points move from sample to sample, the adjustable version saves re-fixturing.
Can it run under vacuum, and what does that change?
The chamber row of the specification lists Vacuum. 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 vacuum arrangement and operating environment are confirmed at quotation.
What about low-current measurements?
The probe signals run on triaxial BNC ×4 — an interface intended for low-leakage measurement configurations. For pA- or fA-class work, confirm the probes, cabling, fixtures, shielding, grounding, and the measurement instrument set 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.
