[Nhcoll-l] Suppliers for large display containers for ethanol preserved specimens

[Mascord, Lucie]

Hi all
Does anyone have any experience with sourcing large display containers for ethanol preserved specimens?
I am working with a museum who are looking to procure a case for a specimen 1.2m in length to go on display. It is not currently on display, and the specimen is preserved in an ethanol solution. Due to the size it is likely we are limited to some type of plastic resin case. Due to the rarity of this specimen, we are not considering a transfer into a different preservative so no advice no that required.
Requirements are based on the large size, the preservative solution, it must be display suitable (i.e. clear) and preferably could be sourced in Europe (or better still UK). The case needs to last for a minimum of 2 years.
We have a quote for a PETG (polyethylene terephthalate glycol) casing. By my research, this appears like it COULD be ok, it shows to be stable for containing 50-96% ethanol (although over what period of time is unknown) and is widely preferred to type 1 borosilicate for lab ware applications. However I have no experience of it working in practice.
Does anyone have experience with PETG display cases for ethanol solutions? And does anyone have advice on compatible sealants for these systems?
Any advice on suppliers and materials are much appreciated. Thank you!
