Products and services

• LSCT100 SEM Cryo Vacuum Transfer System (LSCT100 SEM真空冷冻传输系统) SEM vacuum cryo transfer system that uses liquid nitrogen mud for rapid cryo-fixation of samples, followed by fracturing and sublimation as needed, then cryo-coating, and vacuum cryo transfer to SEM with cold stage and cold trap for imaging. Designed for water-containing, oil-containing, and electron beam-sensitive samples in life science and materials science research.
• LSCT200 FIB Cryo Vacuum Transfer System (LSCT200 FIB真空冷冻传输系统) FIB cryo vacuum transfer system compatible with all brands and models of focused ion beam (FIB) instruments, providing an efficient cold stage for FIB/SEM with continuous rotation and high-angle tilting capabilities. Enables rapid cryo-fixation and FIB cutting under cryo protection for life science samples and protects materials science samples from damage during cutting.
• LSCT102 Vacuum Cryo Transfer System - Thermo Edition (LSCT102 真空冷冻传输系统赛默飞版) Vacuum cryo transfer system specifically designed for electron microscopes equipped with Thermo Scientific cold stages and inert gas sample transfer rods (IGST). Bundles the MSC310 multi-function vacuum cryo experiment chamber and LNS210 liquid nitrogen mud operation platform, and is suitable for water-containing and oil-containing samples and FIB sample cryo preparation.
• EMC10 Electron Microscope Liquid Nitrogen Refrigeration Cold Stage (EMC10 电镜液氮制冷冷冻台) Standalone electron microscope cold stage using liquid nitrogen Dewar and soft copper strip conduction cooling to provide a low-cost, simple-operation cryogenic stage compatible with various SEM/FIB models.
• EMC18 Electron Microscope Cold Nitrogen Gas Refrigeration Cold Stage (EMC18 电镜冷氮气制冷冷冻台) Electron microscope cold stage using cold nitrogen gas circulation refrigeration, delivering fast cooling speed and continuous long-time operation. Compatible with various SEM/FIB models as a higher-performance alternative to liquid-nitrogen-based cold stages.
• SEM110 Electron Microscope Transfer Interface (SEM110 电镜传输接口) Adaptable electron microscope transfer interface available in 40mm, 80mm, 160mm, and 210mm configurations to suit different SEM/FIB models, including special requirements in the semiconductor industry.
