AeraSeal Starter Kit: 1x Dispenser 2 Rolls of AeraSeal Dispenser Excel Scientific's unique SealMate™ system provides a convenient new method for sealing standard-format microplates with adhesive films. The system includes a molded polypropylene dispenser with a hinged “clamshell” design and sealing films supplied in a novel sheeted-roll configuration. AeraSeal Sealing Films (Non-Sterile) A 140 µm thick hydrophobic porous rayon sealing film including medical-grade adhesive for tissue culture plates, bio-blocks, and 96-well plates where gas exchange is necessary for cell or bacterial growth. AeraSeal sealing films minimize cross-contamination, spillage and evaporation. They allow uniform air and CO2 exchange for all wells, unlike plate lids which favor exchange for wells near the plate edges. -Non-cytotoxic, highly gas permeable -Easily pierceable with pipet tips or pipets for sample recovery -Recommended for temperatures from -20 °C to +80 °C -Environmentally friendly green product: reduced waste; no protective backing to remove and discard -Convenient, easy film application for microplanes -Three times faster than sheet films -Inexpensive applicator
