Skin sample culture and membrane test device

An apparatus for high throughput screening, the apparatus comprising:

• a base comprising a plurality of channels for receiving a reagent, the channels being spaced across the surface of the base and having one or more walls which extend through the base from a first base surface to a second base surface;
• a compression member containing a plurality of openings which extend through the compression member and which are positioned across the surface of the compression member, one or more of said openings being positioned for alignment with a corresponding channel in the base;
• and
• a grip for removably securing the compression member to the base such that when a compressible sheet is positioned across the channel between the base and the compression member and fixed by the grip, parts of the compressible sheet are compressed between the base and the compression member to form a seal between the base and the compression member and the compressible sheet and walls of the base form one or more wells for containing the reagent.
