Abstract
A microbiological assembly is provided having a resealable seal between a support and a cover. The support has a surface which includes a patterned layer and defines at least one sample retention well. The cover has a surface which contacts a sealant and the sealant is disposed on at least one of the support and the cover. The sealant is adapted to releasably bond and resealably seal the cover to the support. The sealed assembly minimizes contamination and drying of liquid sample retained by the sample retention well. A method of examining a biological culture is also provided and includes the steps of retaining a biological sample within the sample retention well of the assembly, sealing the cover to the support with the sealant between the sealing surface and the support surface, physically separating the cover from the support surface, and then either resealing the cover or sealing a second cover to the support using the same sealant. Assemblies including magnetic, electrostatic and other resealable seals are also provided.
