LVEM 25E

The Delong LVEM 25E extends the LVEM platform to 25 kV, improving resolution over the LVEM 5 while maintaining bench-top size and the high-contrast advantage of low-voltage operation.

Operating modes:
– TEM: bright-field; 1 nm resolution at 25 kV
– SEM: surface imaging; 3 nm resolution at 25 kV
– STEM: dark-field for nanoparticle characterization
– ED: electron diffraction for phase identification

Versus LVEM 5:
– TEM resolution: 1 nm vs 2 nm; SEM resolution: 3 nm vs 10 nm
– Thicker sections: up to 200 nm versus 100 nm for LVEM 5
– Variable voltage 10-25 kV for contrast vs. resolution optimization
– Still provides higher contrast than conventional 100-300 kV TEM

Specifications:
– Accelerating voltage: 10-25 kV (variable)
– TEM resolution: 1 nm; SEM resolution: 3 nm
– Magnification: 1,000-500,000x TEM; 200-100,000x SEM
– Footprint: 50×60 cm; weight: 80 kg
– Vacuum: integrated turbo pump
– Camera: 11 MP cooled CCD; USB3
– Power: 110-240 V; 2 kVA

Applications: cell ultrastructure, polymer blends, nanoparticle analysis, pharmaceutical formulations, semiconductor failure analysis.
