Gas Permeable Seal Mark 2, 125 x 78 mm, Sterile - 100 Sheets

Our Gas Permeable Heat Seal Mark 2 is made from a woven material and is designed for use in cell culture, due to its porous nature. The small pore size (<20 µm) of this material enables gas exchange, per 24 hours of >20 g/m², whilst evaporation is reduced to a minimum. It can be removed by peeling, or it can be pierced with a pipette tip manually, using a liquid handling robot or with a pierce plate. Gas Permeable Heat Seal Mark 2 can be utilized for effective overnight incubations, during which it demonstrates significant reductions in evaporation compared to lids. This seal is available as sheets, for use with manual and semi-automated sealers, such as our 4s3™ Semi-Automatic Sheet Heat Sealer. Also available in multiple roll formats compatible with specified automated heat sealers, such as our a4S Automatic Roll Heat Sealer.
