EM-Tec metallographic mount holders
EM-Tec metallographic SEM mount holders are designed to hold metallographic, petrographic and ceramographic mounts or embeddings. These practical and sturdy holders are equally useful holding round SEM samples with size similar to the mounts or for holding larger cylindrical SEM specimen stubs. They are 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. Longer screws are also 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 on SEMs which use standard pins, eg 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 EM-Tec versatile SEM stage adaptors
- Ø14mm JEOL stub compatible with JEOL and EM-Tec stage adaptors with a Ø14mm connection
