SEM Stage ASCH200/ASCH200-RS
Product Detail
InSitu Pro™ ASCH200 and ASCH200-RS are SEM heating and cooling stages for in-situ electron microscopy: liquid-nitrogen cooling and resistive heating at ±0.1 °C stability. The ASCH200 runs −190 to 200 °C — max heating 150 °C/min, max cooling 30 °C/min — on a gold-plated copper 23 × 23 mm sample stage, installs through a custom external flange device without modifying the microscope's internal structure, and provides setpoint, ramp, and multi-segment program control with real-time capture of the sample's microscopic dynamic processes and excellent electromagnetic-interference shielding. The ASCH200-RS is a rotary stage with X/Y/Z/R/T five-axis freedom in FIB/SEM: −180 to 200 °C on a copper φ30 mm stage, enabling samples to be transferred and tested in the low-temperature state.

Cryogenic cooling inside the microscope: plan the run
Set the target temperature your electron-microscopy 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 ASCH200 cools with liquid nitrogen at up to 30 °C/min toward its −190 °C floor; the ASCH200-RS at up to 15 °C/min toward −180 °C:
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. The simulator's LN₂ curve is family-level: the ASCH200 and ASCH200-RS are specified at max cooling rates of 30 and 15 °C/min toward −190 and −180 °C respectively, so their specified maximum rates sit below the illustrative curve. For the technologies compared here, TEC-based InSitu Pro™ stages are specified down to −25 °C, while the ASCH200 series uses liquid-nitrogen cooling; 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
Will it fit my SEM?
The ASCH200 installs through a custom external flange device, so no modification of the microscope's internal structure is required; the ASCH200-RS mounts in FIB/SEM with X/Y/Z/R/T five-axis freedom. Tell us your microscope model when requesting a quote and our engineers confirm the flange, mounting, and configuration.
ASCH200 or ASCH200-RS — which one?
Choose by motion first: the ASCH200 is the external-flange stage with the wider −190 to 200 °C range and faster rates — max heating 150 °C/min, max cooling 30 °C/min — on a gold-plated copper 23 × 23 mm stage; the ASCH200-RS is the rotary stage with X/Y/Z/R/T five-axis freedom in FIB/SEM, running −180 to 200 °C at max heating 30 °C/min and max cooling 15 °C/min on a copper φ30 mm stage. Cooling method, ±0.1 °C stability, and the basic configuration are identical.
Will it disturb imaging?
The ASCH200 is specified with excellent electromagnetic-interference shielding and enables real-time capture of the sample's microscopic dynamic processes during heating and cooling. Instrument-specific compatibility is confirmed at quotation.
Can I transfer samples at low temperature?
The ASCH200-RS supports transferring and testing samples in the low-temperature state within its −180 to 200 °C range. The transfer workflow for your instrument is confirmed at quotation.
How does temperature control work?
Liquid-nitrogen cooling and resistive heating are managed by the included temperature controller and cooling controller at ±0.1 °C stability — with setpoint, ramp, and multi-segment program modes on the ASCH200 — at max heating 150 °C/min and max cooling 30 °C/min on the ASCH200, and max heating 30 °C/min and max cooling 15 °C/min on the ASCH200-RS. The standard configuration includes a 2.5 L liquid-nitrogen tank, a water-circulation system, and the temperature-control software.
