TRADITIONAL microplate seals create a hermetic seal over each microplate well, cutting it off from the outside world and preventing contamination. Such a complete seal, however, also prevents gas from passing through and can limit the usefulness of live cell culture.
Porvair gas permeable microplate seal prolongs cell life
Now Porvair Sciences has introduced its 500120 series gas permeable adhesive microplate seals, which allow air and carbon dioxide (CO2) to be exchanged, but prevent the evaporation of moisture. It says this makes them suitable for eukaryotic cell culture and long-term live cell assays.
The gas permeable film is bonded to an adhesive sheet, which aligns the adhesive over the well walls but not over the wells themselves. The seals are available with either 96 round adhesive-free windows, or 384 square, and provide high integrity microplate closure from -20C to +80C.
Porvair’s 500120 series microplate seals are supplied in packs of 50 (five stacks of ten sheets), and can be easily peeled for application to the microplate.
