CLOSED MULTI-WELL ANALYTICAL PLATE WITH ANNULAR ADHESIVE PATCHES FOR ANALYTICAL OPTICAL MEASUREMENTS

摘要

. According to the invention, the collecting-chamber openings of the multi-well analytical plate, generating largely reliable analytical results also at elevated temperatures and over a long period of time, are sealed with an optically clear sealing material, for example, clear plastic film, or a glass sheet. The adhesive for fixing the sealing material which covers the collecting-chamber openings is only applied to the contact area of the sealing material with the multi-well analytical plate and not to the area of the collecting-chamber opening. Neither the sealing material itself, nor the means of fixing to the multi-well analytical plate thereof, in particular, hot-melt adhesives impede the light flux from and to the samples for optical analytical determination.
