Re: Cork discs.

From:Barry Rittman <>

cork discs provide an excellent mechanism for orienting small pieces of tissue, as plastic coverslip can be inserted in a slot in the cork and the tissue arranged on
these. The cork disc also provides a convenient system for labeling so that multiple specimens, on  separate corks,  can be stored in one box.
As far as being a poor conductor, the tissue is small and is usually floated face down in the solution so that the conductivity of the cork is a mute point.
