Rave Scientific offers the EM-Tec EM-Storr vacuum sample storage containers. The EM-Storr containers have been specifically developed to store and protect SEM/FIB/TEM samples and calibration standards under vacuum. An end user can source the entire turnkey package from this page:

  • Container
  • Replacement O-ring
  • Vacuum hose
  • Clamp

The EM-Storr vacuum container protects valuable samples from air, moisture and dust. The superior EM-Storr vacuum container is constructed using high vacuum compatible materials: vacuum grade aluminum, a hardened safety glass lid, NBR O-ring and an all metal high vacuum valve with PTFE shaft seal. The outside of the aluminum container is hard anodized for protection. To reduce out-gassing and to hold vacuum for extended periods, the inside surface is machined vacuum grade aluminum with a glass lid. The EM-Storr vacuum desiccator is capable of reaching vacuum in the 10-4 mbar range. The vacuum connection for pump-down is a 6mm (1/4”) barbed hose fitting – compatible with 6mm thick wall silicon vacuum hose.  The EM-Storr vacuum containers are stack able; the octagonal design is optimized for handling, strength and weight.
