A simple modular tissue bath developed for 'in vitro' studies of the isolated spinal cord.

A tissue bath for studies of the mammalian spinal cord in vitro is described. The modular construction of the bath permits considerable flexibility for accommodating different tissue preparations. The individual components of the bath are easily constructed and the design permits multiple compartment baths to be simply formed. The design principle on which the bath is based may have much wider application than that described.
