Pin Mount SEM Specimen Holders & Tungsten Filaments
Optimize your electron microscopy workflow with our precision-engineered sem specimen holder solutions. Manufactured from high-grade machined aluminium with stainless steel Allen screws, our sem pin stub mount collection is designed to securely anchor your samples. The standard sem pin mount 3.2 mm pin ensures universal compatibility with major brands like Zeiss, LEO, Leica, FEI, Philips, and Tescan.
Complementing our robust hardware, we supply premium tungsten filament electron microscopy consumables. These high-purity, V-shape tungsten hairpin filaments act as the ultimate thermionic electron source, delivering exceptional brightness and longevity for high-resolution imaging in both SEM and TEM environments.

Comprehensive Capabilities of SEM Holders
-
Robust Material Construction Every machined aluminium sem holder features stainless steel Allen screws and spring-loaded mechanisms. This ensures a tight grip on your sem pin stub 12.7 mm or 25.4 mm mounts, preventing vibration during high-magnification scanning.
-
Extensive Sample Diversity Whether you require a sem bulk specimen holder for large geology samples, a sem holder for metallographic mounts, or a specialized sem holder for wafers and flat samples, our range covers it all.
-
Universal Instrument Compatibility The standard sem pin stub 3.2 mm diameter ensures these holders act as the perfect sem specimen holder for fei philips, Zeiss, Leica, and Tescan platforms. (Note: Specific adapters may be required for sem holder for jeol systems).
High Brightness Tungsten Filaments
-
Premium Electron Emission Our pure tungsten filament electron gun replacements feature a precise 100 µm wire V-shape. This creates a superior thermionic electron source that generates brilliant, stable electron beams.
-
Extended Longevity Designed as a long life tungsten filament sem, these emitters resist early degradation, ensuring fewer gun interventions and more uptime for your sem electron gun replacement filament needs.
-
Direct OEM Replacements We provide exact-match tungsten filament replacement sem components, guaranteeing compatibility as a tungsten filament for zeiss sem, Hitachi, FEI, and Jeol microscopes.
Frequently Asked Questions
The industry standard for a sem pin stub mount is a 3.2 mm (1/8 inch) pin diameter, which is compatible with major systems including Zeiss, LEO, Leica, FEI, Philips, and Tescan.
We offer a range of capacities to suit your throughput needs, from a basic sem pin mount holder 4 stubs up to high-capacity models like the sem holder 29 pin stubs and the sem holder 49 pin stubs.
A sem 45 degree pre-tilt holder allows you to increase the Secondary Electron (SE) signal without needing to physically tilt the heavy microscope stage, ensuring stability and safety during high-resolution imaging.
Electron microscopes utilize a tungsten hairpin filament (typically a 100 µm V-shape wire). This acts as a high brightness tungsten filament and serves as the primary thermionic electron source for the electron gun.
Yes, we supply highly pure tungsten electron emitters designed as direct replacements. We offer specific models including the tungsten filament for jeol sem, hitachi sem, zeiss sem, and fei sem.
