EM-Tec metallographic mount holders
EM-Tec metallographic mount holders are designed to hold metallographic, petrographic and ceramographic mounts or embeddings in an SEM. These practical and sturdy SEM holders are equally useful holding round samples with similar sizes to the mounts or for holding larger cylindrical SEM specimen stubs. Available for all standard metallurgical mounts from 25 to 50mm diameter (1” to 2”). The samples are secured with an M3 set screw (an allen key is included with the holder). Additional longer screws are supplied to hold smaller samples. They are all made from vacuum grade aluminium and have undergone a final cleaning step which results in a satin surface finish. Available with:
- Standard pin to fit SEMs: ThermoFisher Scientific/FEI, Philips, Tescan, Phenom, Pemtron, Cambridge Instruments, Leica, CamScan SEMs.
- M4 threaded hole compatible with Hitachi SEMs, FE-SEMs and table top SEMs and with the EM-Tec versatile SEM stage adapt0rs
- Ø14mm JEOL stub compatible with JEOL and EM-Tec stage adaptors with a Ø14mm connection
