LaB6 High-Brightness Filament

ZEM20 PRO

The High-Resolution Choice for Desktop Scanning Electron Microscopes

3nm Resolution | 500,000x Magnification

Brighter, Clearer 
A Smarter Desktop SEM

The ZEPTOOLS ZEM20 Pro Desktop Scanning Electron Microscope is equipped with a high-performance LaB6 filament, delivering excellent core performance metrics with a maximum magnification of up to 500,000x and a resolution accurate to 3nm. It meets the core needs for high-precision microscopic observation in fields such as university research microstructure characterization, semiconductor failure analysis, and new material performance research, making it one of the preferred high-resolution desktop SEM solutions for scientific experiments and industrial inspection scenarios.

The product is deeply adapted to users' needs for efficient operation, integrating intelligent functions such as automatic brightness and contrast adjustment, auto-focus, and large-image stitching, greatly lowering the operating threshold. Even research assistants or entry-level inspection personnel can quickly complete high-quality imaging, effectively solving the pain points of traditional SEMs such as cumbersome operation and low imaging efficiency.

This model features an extra-large sample chamber design, allowing flexible integration of various in-situ expansion platforms to accommodate the experimental and inspection needs of samples with different materials and sizes. Whether it is in-situ growth observation of new materials, failure localization analysis of semiconductor devices, or micromorphology research in the biomedical field, it can provide stable and reliable technical support, further expanding the application boundaries of desktop SEMs.

ZEPTOOLS ZEM Series SEM Helps Research Teams Publish High-Level Journal Achievements

Nature Sub-Journal: Fiber-Integrated Graphene Ultrafast Electron SourceZEPTOOLS ZEM Series Desktop SEM served as the demonstration platform, replacing the original tungsten filament gun with a fiber-integrated graphene ultrafast thermionic electron gun, achieving pure pulsed electron imaging (~100 nm resolution) and CdSe/ZnS quantum dot cathodoluminescence/time-domain spectroscopy measurements, verifying that this light source is plug-and-play on conventional electron microscopes and enables time-resolved characterization.

New Strategy for Bladder Cancer ImmunotherapyZEPTOOLS ZEM Series Desktop SEM was used for BCG-MBs morphological characterization. After gold sputter coating of lyophilized microbubbles, multi-magnification observation revealed their regular spherical contours and smooth surfaces, and clearly presented the irregular attachment of BCG bacteria on the shell surface, providing direct microscopic evidence for the successful construction of microbubble structures and drug loading distribution.

Aluminum Alloy/PEEK Friction Lap WeldingZEPTOOLS ZEM Series Desktop SEM was used to characterize the cross-section and fracture surface micromorphology of 5052Al/PEEK friction lap welded joints, clearly presenting the interfacial molten layer, spherical bubbles (approximately 500 μm), and the ridge-like PEEK strong bonding zone adjacent to the bubbles, providing direct microscopic evidence for the regulation of bubbles by heat-pressure ratio U and the establishment of interfacial bonding mechanisms.

Ferroelectric Domain Coupling Mechanism of Polycrystalline PZT CeramicsZEPTOOLS ZEM Series SEM was used to observe the fracture surface morphology of 75/25PZT and Mn/Nb-doped samples before and after quenching, statistically analyzing the average grain size (approximately 1.8–5.1 μm and essentially unchanged after quenching), corroborating that the changes in electrical properties originate from domain structure rather than grain size or grain boundaries.

Powerful Tool for Triple Barrier Structure Morphology CharacterizationZEPTOOLS ZEM Series Desktop SEM was used to observe the micromorphology of cellulose/chitosan coaxial cryogel fibers (CCF): clearly presenting the triple barrier structure of the regenerated cellulose sheath layer (~1 μm pores), the retained air layer between sheath and core (approximately 200 μm), and the chitosan core layer (<500 nm nanopores), providing direct morphological evidence for the thermal insulation mechanism.
