Apparatus for handling compound storage vessels such as microtubes having a least one cavity for receiving a compound storage vessel. Each cavity is associated with a respective detector operative to detect the presence of a storage vessel in the cavity. The detector may comprise a spring form extending in the cavity and arranged to be deformed by a storage vessel when introduced into the cavity, and further arranged so that on deformation it closes an electrical switch indicating the presence of the microtube in the cavity. The presence of the spring form also increases friction between the storage vessel and the cavity retaining the storage vessel within the cavity.
