CPE50 Cryogenic Peltier Microscope Stage with -50°C to RT Range, ±0.1°C

The GoGo CPE50 is a specialized Peltier Microscope Stage engineered for precise low-temperature in-situ observation under controlled atmospheric conditions. Operating from -50°C to room temperature with exceptional stability of ±0.1°C, this system integrates a sealed atmosphere chamber to prevent sample contamination and optical window frosting—a critical challenge during sub-zero experiments. Utilizing eco-friendly Peltier (TEC) technology, it achieves vibration-free, consumable-free cooling at rates up to 30°C/min. This Peltier Microscope Stage is ideal for materials science, cryobiology, semiconductor testing, and optical spectroscopy applications requiring reliable, long-duration thermal control without liquid nitrogen logistics.

• Atmosphere Protection for Low-Temperature Integrity:

  This Peltier Microscope Stage features a sealed chamber that allows purging with dry inert gas or creation of a low vacuum, effectively eliminating frost formation on samples and windows. This ensures clear optical access and protects sensitive materials from moisture and oxidation during cryogenic experiments.

• Eco-Friendly, Vibration-Free Peltier Cooling:

  Unlike liquid nitrogen systems, this stage uses solid-state thermoelectric technology for clean, quiet operation with no consumables. The absence of mechanical vibration is critical for high-magnification microscopy and nanoscale imaging applications.

• Superior Thermal Performance & Stability:

  Achieves rapid cooling (30°C/min) to -50°C while maintaining laboratory-grade ±0.1°C stability, ensuring reproducible results for temperature-sensitive experiments across materials science, life sciences, and electronics testing.

• Versatile Optical & Sample Compatibility:

  The reflection optical path with a high-transmission JGS2 window (220-2500 nm) accommodates various microscopy and spectroscopy techniques. The 40x40mm copper sample holder ensures excellent thermal conductivity for uniform sample cooling.

• Complete, Ready-to-Use Solution:

  Supplied as a turnkey system with TNEX software for automated temperature profiling, this Peltier Microscope Stage includes all necessary components for immediate integration into your research workflow.

This versatile Peltier Microscope Stage is ideally suited for research institutions in key growth regions including Southeast Asia, the Middle East, Russia, and Africa. It serves university laboratories, government research institutes, and industrial R&D centers in materials science, cryobiology, semiconductor testing, and optical spectroscopy.

1. Why is an atmosphere chamber essential for low-temperature microscopy?

   At temperatures below 0°C, atmospheric moisture condenses as frost on cold surfaces. The sealed chamber allows dry gas purging (e.g., nitrogen) or vacuum, preventing frosting and ensuring uninterrupted optical observation.

2. What are the advantages of Peltier cooling over liquid nitrogen?

   This Peltier Microscope Stage offers vibration-free operation, no consumable costs, and simplified setup—ideal for long-duration experiments requiring stable low temperatures without the need for LN₂ refills.

3. What applications is this stage best suited for?

   Key applications include cryo-biology (cell/tissue preservation), low-temperature electrical testing of semiconductors, Raman spectroscopy, and studying brittle-ductile transitions in polymers and metals.

4. Is the system compatible with high-magnification objectives?

   Yes, the low-profile design (40mm height) and 4.8mm working distance provide ample clearance for most high-magnification objectives.

5. What is included in the basic configuration?

   The system includes the CPE50 stage, temperature controller, recirculating chiller, TNEX software, and all cables/tubing for immediate operation.
