[NHCOLL-L:4385] Re: PETE Container for Malacology Collections

[CAHawks at aol.com]

Any plastic approved for food use probably contains BHT (butylated  
hydoxytoluene) which is an antioxidant approved by the FDA. It will leach  into the 
contents of the container, staining specimens and potentially damaging  the 
utility of the specimens for chemical analysis.

Finding archival storage  containers for malacology collections has been a 
challenge for our  curator.  We use a combination of acid-free boxes, glass 
vials, and the  PET clamshell boxes (from Gaylord) but we’ve been looking 
for something to  replace the smaller sized acrylic boxes with snap lids.    
Recently the curator has found 2oz  and 4oz round containers with separate 
flat lids both components are made of  PET by two companies, Solo and Sysco. 
 My concern is that they are coated  with something to accommodate food, 
like the Ziploc bags.  Has anyone  used these containers?  Or done any 
research?    
I realize that we can get the PET  containers from Gaylord in custom sizes 
but funds are always an issue and off  the shelf products can be cheaper. 
Thanks,
