The EM-Tec EM-Storr vacuum sample storage container has 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.
