My DMSO from Jeffers comes in plastic bottles. DMSO freezes about 67 F so it could break a glass container pretty quick.
don't think it would do anything else to the glass but why use something that could break ? ----- Original Message ----- From: "J&S Campbell" <[email protected]> To: "Terry Chamberlin" <[email protected]> Sent: Wednesday, September 21, 2005 6:16 AM Subject: Re: CS>Glass vs plastic > > Thanks very much for posting this. > Do you know has any work been done on the > storage of DMSO in glass versus plastic.
