CGO-2 Magnetic Field Probe Station

Category:

CGO Series Vacuum High- and Low-Temperature Probe Station

Uses
- Cindbest's CGO-2 provides cryogenic environments with vacuum levels as low as 10⁻³ Pa or 10⁻⁶ mbar.
- Magnetic field strength: >±0.5 T @ 100 mm horizontal magnetic field
- Meeting the requirements for non-destructive measurement of electrical and magnetic properties in materials and early electronic devices
- Typical applications include sampling IV and CV curves over a wide temperature range, measuring microwave and electro-optic responses, characterizing magnetic transport properties in variable magnetic fields, performing Hall effect measurements to determine carrier mobility, and conducting a variety of other materials research.
Complete machine assembly
- Taiwan module, magnetic field module (including electromagnet, Gauss meter, and water-cooling unit), probe arm module, optical microscopy system, vacuum system, high- and low-temperature control system, rack module, and instrument cabinet.
Features
- High-vacuum chamber with a temperature range of 77K–473K;
- Provide efficient cryogenic operation by using liquid nitrogen or liquid helium to achieve continuous cooling of the system.
- No water or frost formation at low temperatures, ensuring samples remain dry.
- Affordable—highly competitive pricing among products in the same category;
- Integrated seismic isolation design eliminates the need for an optical platform, occupying less space and providing a superior experimental environment for laboratories.
