The planchets are made of Beryllium with a 99% or better purity and any of the possible
impurities will not exceed 0.08% . In fact most of the possible impurities are well
below 0.01%. Using proper cleaning and safety procedures the planchets can be used
again. Available in three sizes to fit the most widely used specimen mounts. Surface
finish is smooth: 1.6µm or less and is perfectly suitable for many applications.

Warning: Cleaning and handling of Beryllium must be done in such a way that it does not generate particulates which are toxic when inhaled.
An alternative for beryllium planchets could be
graphite planchets
which also gives a low background and virtually no characteristic peaks other than carbon.
