Hello again, I have a follow up question about handling air sensitive sample. Some of you mentioned vacuum sealing like which used for food, this reminds me a aluminized mylar bags. Does anyone know a good source to get thine aluminized mylar bags. It seems that the standard thickness is about 0.1mm, just wondering if there is a well known source who makes bags thinner than that. Thank you!
