Precise processing involves scanning the sample surface with accelerated gallium ions at both room temperature and cryogenic temperature (-190℃). This enables the observation of the sample surface and the manufacturing of lamella with meticulous precision. Specifications Electron optics Acceleration voltage : 200 V~30 kV, Beam current range : 1.5 pA~400 nA Ion opticsVoltage : 500 V~30 kV Beam current : 1.5pA~65nA Resolution(on cold stage) : 7 nm(30 kV) |
High pressure freezing preserves hydrated biological samples by rapidly freezing them under approximately 2,100 bar. This suppresses ice crystal formation and promotes vitrification, allowing cellular and subcellular structures to be preserved close to their native state. Specifications Freezing pressure: Approximately 2,100 bar Sample thickness: < ~200 µm Freezing state: Vitrified (amorphous) ice |
Mass photometry is a simple, easy-to-use technology that rapidly analyzes biomolecules at the single-particle level in solution. It measures the light scattered by individual particles and uses the signal to count the particles and measure their mass with high accuracy. Mass photometry measurements provide the mass distribution and relative concentrations of a wide range of biomolecules in a sample, accelerating a variety of studies, including: • Sample purity and homogeneity • Protein oligomerization • Biomolecular interactions • Macromolecular complex assembly |
