On-site Equipment Integration & Verification

Addressing the key industry challenge of testing 2D materials, which are highly sensitive to water, oxygen, and contaminants, this system has been optimized through extensive R&D and validation. Equipped with specialized accessories for 2D materials, it delivers high-precision temperature control across the full operating range:Within a temperature range of -190°C to 300°C, samples exhibit no frost formation or discoloration when observed under a 50× optical microscope, effectively resolving a critical bottleneck in 2D material testing.
