1. A device for replicating bacterial or other cell colonies comprising a layered structure of(i) a rigid layer means;
- (ii) a backing layer made of flexible foam which is secured to one side of the rigid means;
(iii) a transfer layer which is attached to the side of the backing layer opposite from the rigid means and which is made from open-cell, porous, flexible foam; and
(iv) a hydrophilic material included within the transfer layer and at its exposed surface, the hydrophilic material-containing foam transfer layer being air-porous and compliant but less resilient than the foam backing layer.
