摘要
An array of reaction tube covers adapted to seal a plurality of reaction tubes comprises a unitary body of flexible material having a plurality of flexible plastic nodules. Each nodule is adapted to seal one of the reaction tubes. Each of the nodules is flexible held in a predetermined planar spaced relationship from each other in rows, preferably in rows and columns, by an integral web having a plurality of apertures therethrough. Each of the nodules has a downwardly convex, generally hemispherical lower portion extending from the web, an upwardly convex upper portion extending from the web over the lower portion, and a centrally domed nipple extending upwardly from the upper portion.
