Peltier Heating and Cooling Stage APE120/APE120V
Product Detail
InSitu Pro™ APE120 and APE120V bring sub-ambient microscopy without cryogens: Peltier (TEC) electric cooling and heating cover −25 °C to 120 °C at the flip of a switch — no liquid nitrogen, no dewars, no refills. A large copper 40 × 40 mm stage carries bigger samples than the LN₂ family, in an atmosphere chamber (APE120) or a vacuum chamber (APE120V) that suppresses condensation during sub-zero work.
Key features
- ±0.1 °C with three control modesFixed-point, ramp, and multi-segment programmable profiles across the full −25 to 120 °C range.
- No cryogens, everThermoelectric (Peltier) cooling and heating run on electricity alone — switch on and measure, with no LN₂ logistics, no refilling, and no consumables budget.
- −25 to 120 °C windowCovers the sub-ambient and gentle-heating band where most condensation, biological, polymer, and device work lives — ramping at up to 30 °C·min⁻¹ both up and down.
- Large copper 40 × 40 mm stageNearly three times the area of the LN₂ family's 23 × 23 mm stage — room for bigger specimens, multiple samples, or full devices, with copper's excellent thermal uniformity.
- Two chambers to chooseAPE120's atmosphere chamber gives the fastest everyday workflow; APE120V's vacuum chamber suppresses condensation in sub-zero runs and keeps the sample environment controlled.
- InSitu Pro™ family engineeringBuilt alongside the optical stage range and its controller ecosystem, on the same microscopes and Raman systems.

Do you even need LN₂?
The planner below is this family's home turf: the TEC curve is the Peltier engine, rated to a −25 °C floor. Set your target — if it sits at −25 °C or above, the APE120 series gets you there on electricity alone; colder targets belong to the LN₂ family.
Model: controller-limited linear ramp with a Newton-type approach near each technology's floor. Takeaway: the TEC floor of −25 °C is exactly this family's rating — above it, Peltier is the simplest, cleanest way to cool. Curves are schematic family-level behavior, not a guarantee for a specific unit.

Matched controller set — no cryogen hardware to buy. The APE120 series runs on its matched temperature controller, water-circulation system, and PC software: no dewars, no LN₂ supply, no auto-refill hardware. The matched set is specified with your quotation.
FAQ
APE120 or APE120V — which one?
Pick by what happens below 0 °C. In air, a sub-zero stage grows frost and dew that ruin imaging; the APE120V's vacuum chamber removes the moisture supply, keeping optics clear through long −25 °C holds and giving you a controlled sample environment. If you work mostly above room temperature or in short sub-ambient dips, the simpler APE120 is all you need.
Peltier or the LN₂ family?
Decide with your coldest target. At −25 °C or warmer, TEC wins on simplicity: no cryogen logistics, instant start, clean bench. Below −25 °C — or above 120 °C — step up to the LN₂ optical family (−190 to 600 °C). The simulator above makes the crossover obvious.
What fits on a 40 × 40 mm stage?
Nearly 3× the area of the LN₂ family's stage: larger specimens, several samples side by side for comparative runs, or complete small devices — with copper's thermal conductivity keeping the surface uniform.
