Porvair Sciences Introduces Gas Permeable Rayon Microplate Sealing Film
Product News Jun 20, 2008
Porvair Sciences has introduced a new gas permeable Rayon microplate sealing film that has been shown to improve culturing of mammalian cells, bacteria and yeast culture by up to 70% compared to an impermeable seal.
Manufactured from high permeability, medical grade Rayon the new heat sealing film can provide a uniform air and CO2 exchange with all microplate wells, unlike plate lids which favour exchange for wells near the plate edges. The breathable membrane can also reduce evaporation enhancing longer term incubation experiments.
According to company, offering a high quality seal with all SBS / ANSI format microplates the new gas permeable Rayon sealing film allows direct sample recovery with single or multichannel pipettors and robotic probes.
Designed for use with both manual and automated heat sealers the new sealing film uses a non-cytotoxic adhesive to minimize sample cross-contamination. Though available sterile the new gas permeable Rayon microplate sealing film cannot be autoclaved without reducing permeability.
