The gas permeable adhesive seal provides a simple and effective way of venting cultures whilst providing a barrier against contaminating bacteria. When used in conjunction with Thermo Scientific storage plates, bacterial growth can be increased by over 50%, compared to plates sealed with an aluminium foil seal or sealing mat.

• Forms an effective seal between −20 and +80 °C
• Possible to apply other adhesive seals and lids over the gas permeable seal, thus allowing safe storage of cultures and samples
