Inquiry (采购产品): Permeable Plastic sheet I am a researcher at Cornell University. I have been carrying out work to extract the alpha cellulose from wood samples. This involves placing a gram of wood chips in an sealed, porous, inert container and putting it through a series of strong (hot) acidic bleaches. We have developed a method using 1 inch bags made of a permeable teflon like material, cut and heat sealed into pouches which are then cut open and disposed of after analysis. We have been unable to source a new supply of this material and are looking for an alternative. Can you help? Do you have a material which could be used as described above? Or can you suggest an alternative. Seal-able, permeable plastic thimbles would be a workable alternative possibly? But ideally we would like a flexible sheet and heat seal system so we can make our own pouches as and when. I'd be extremely grateful to hear from you on this as soon as possible and for any suggestions you might have.
