The EM-Tec EM-Storr vacuum sample storage container have been specifically developed by us, to store and protect SEM / FIB / TEM samples and calibration standards under vacuum. It protects valuable samples from air, moisture and dust. The superior EM-Storr vacuum container is constructed using high vacuum compatible materials: vacuum grade aluminim, a hardened safety glass lid, NBR O-ring and an all metal high vacuum valve with PTFE shaft seal. The outside of the aluminium container is hard anodised for protection. To reduce outgassing and to hold vacuum for extended periods, the inside surface is machined vacuum grade aluminium 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 stackable; the octagonal design is optimised for handling, strength and weight.

The EM-Tec Save-Storr sample storage containers have been developed to store sensitive samples under a dry and inert gas atmosphere.  The EM-Tec Save-Storr sample storage containers consist of a clear polycarbonate hinged container with a seal, separate gas inlet and outlet valves and an over-pressure safety valve. The containers can be purged and filled with dry inert gas such as Nitrogen or Argon to protect moisture and oxygen sensitive samples. The construction allows vacuum pumping of the EM-Tec Save-Storr container first,  before purging/filling it with inert gas. Using inert gas to protect samples is preferred for long term safe sample storage. The gas diffusion rate is lower than with vacuum storage containers due to the similar pressures in and outside the container.
The EM-Tec Save Storr sample containers are available in four versions:
