[Nhcoll-l] Storage query

Jon,  When you refer to "resistol" label paper, are you referring to Resistall paper, 36 lb. etc.?


If this is the material used to label the shell collections, keep in mind that the pH is 5.31.  Typically, Resistall (https://urldefense.proofpoint.com/v2/url?u=https-3A__www.bioquip.com_Search_DispProduct.asp-3Fitemnum-3D1223RA&d=DwIFAg&c=cjytLXgP8ixuoHflwc-poQ&r=LpYc_Z_iN1KRw0hheb3x6-8MJUMu482qfHowpGYJqwc&m=b_nYD8Y3-z4Mdec9UA5F2Ypr9pAiukD_XtTCx5ri5Gg&s=kDH6vicAfUgy6TBtMtYeeQuOij9V-0sx8p8oH0CJROQ&e=) is used in fluid preserved collections because it is stable in fluids like ethanol and formalin.  Even then, the pH is of concern in how it affects specimens.  In a dry shell collection, the paper could possibly have detrimental affects.


Our museum divisions share a direct thermal transfer printer (DataMax), which prints on (inert) polyspun plastic paper.  In the past, I have used Tyvek (a flashspun high-density polyethylene paper) for genetic-tissues and whole specimens as well as dry samples with good results.


Over the years, I have cautioned managers of dry collections not to use Resistall as a label paper in dry collections due to it not being acid free.

Hi Mandy,

At the NHM in London we use clear archival/conservation grade press-seal bags and then store these in archival trays. We find this works better than tubes as specimens can be examined without removing them, labels can be stored flat and older labels can be housed in archival pockets. Smaller specimens are kept in glycerin capsules (previously in glass tubes) within the bags.

We don't tend to write the registration on the shell, although this was done in the past. We add a specimen label written on resistol.

I hope this helps. Any questions please let me know.

Jon

Hi
I manage the Malacology collection at the Australian Museum in Sydney. Our larger dry specimens (too big for vials) are currently stored in open trays in archival boxes with their labels. The larger specimens each have their registration numbers written in fine ink on the shells. This makes it easier to notice if a shell becomes misplaced in the wrong box and if a tray is dropped they can be matched to registration numbers.

We had a volunteer who did nothing but write on shells for 30 years. This volunteer is now over 90 years old and has, at last, resigned her post.

I am trying to explore alternative and less labour intensive storage and am wondering how other museums deal with dry shell collections. I have thought of press-seal bags but am not sure how plastic might affect shells in the long term, and it is likely these may get caught when trays are slid in and out of drawers. Clear bags would be preferred.

If anyone has any suggestions
