Dear SPNHC list:
Thanks for all the responses to my question regarding the use of jar sealing
tape with fluid preserved collections. Many people asked me to forward
comments as they too were interested in hearing the responses. Below are
the replies cut & pasted into a single document.
Thanks again for all your help.
Cheers,
Janet

Hello Janet,
I work for the Conservation Section at the Canadian Museum of Nature.
Unfortunately 3M stopped making the tape referred to in Michele Steigerwald
and Sylvie Laframboise's paper so we found an alternate product. Here is
the information for it:
Description: polypropylene tape with acryclic adhesive
Item No.: ST-408C (blue) - there are other colours available
Company: Spectape Inc.
2771 Circleport Drive, Erlanger, KY 41018
Phone: (859) 283-2044

Hi Janet,
I was wondering what response you had from NHCOLL about the tape. I
want to use tape in my collection to reduce evaporation and was just
about to do some investigating re. tape sources myself.
Coincidentally, I just received the SPNHC newsletter and the cover
story is on the use of that tape but they have it listed as 3M
product #8086 (not 5086).
If you could let me know what you found out I would be really
appreciative. I'm sorry that I don't have more to contribute at this
point.
Cheers,
Lisa Greene,
Collections Manager.

Hi, Janet
I bought the 3M #8086 builders sealing tape from EFI (Energy Federation
Incorporated). Their number is 800-876-0660 or you can order online at
www.efi.org <outbind://32/www.efi.org>
The tape is about $15 a roll. I could only find the wide tape, in red. This
tape was recommended to me by Cathy Hawks, conservator, who conducted our
wet specimen collection condition survey last August.
I hope this helps!

Janet,
I'm not familiar with the tape suggested by Steigerwald and
Laframboise (1996), but I do manage a collection of fluid-preserved
specimens and have a few suggestions. When starting with new containers,
consider vials with polyseal caps, small and medium size jars using caps
with Teflon or polyethylene liners, and for larger jars, canning jars with
clamp-type glass lids and rubber or plastic gaskets. Although these
containers still need to be periodically checked for fluid loss (usually due
to loose lids, cracked gaskets, or imperfections on the glass edge that
contacts the sealing material of the lid), they are very effective in
preventing evaporative loses. For older containers with threaded caps,
consider using Teflon plumbers tape on the threaded surface before applying
the cap (this white film-like tape is available in hardware stores). I also
"Parafilm" (American National Can of Chicago), a flexible, moldable
(stretchable), self-sealing laboratory film (the same stuff chemical and
biological laboratories to temporarily cover and seal flasks, beakers and
petri dishes). I've stretched the film over jar tops, including the
threads, before putting on the lids, or cut strips and just stretched them
around the threads before putting on the lids (much like the Teflon plumbers
tape). I have also effectively stretched Parafilm strips around the outside
of the lid (or stopper) and adjacent glass surface which seals the
containers as well or even better than applying melted paraffin wax..
I hope you find these suggestions useful.

Janet,
It is advised to begin by using good jar lids. At SIO we have had very good
success with the polypropylene jar lids with the F217 liner, which is Teflon
coated with a foam backing. This allows for a good seal on the rim of the
jar. Taping is not necessary with these lids. They cost a little more, but
are worth it. If you have the old black Bakilite lids throw them out or
tape them. Electrical tape is sometimes used, but there must be better
tape. Perhaps someone else will have tape suggestions.

Janet,
Our herp collection uses Parafilm to seal the jars prior to screwing on
lids. This seems to work very well.

We have bought it at building supply stores. It's used to seal vapor
barriers, important in subarctic climates, and works well when correctly
applied.
