[Nhcoll-l] 5" Hydrometers

[Murphy, Kris]

Dear listserv,
I am interested in knowing if anyone has recently bought hydrometers with this description:
Hydrometer, 5" long, 60-90% Ethanol @ 70 degree F in 1 degree Divisions, approximately $39 each.

3 years ago, we purchased a dozen of these hydrometers for use in our alcohol collection in the Division of Fishes at the Smithsonian Institution.  We have been unable to locate the same hydrometers.  We purchased these from Thermo Instruments, Inc. from Yaphank, NY and they are no longer in business and/or were bought up by FisherSci.  FisherSci has hydrometers but not 5" in size.  Carolina Biological does not have the 5" size either.

Does anyone use this 5" size hydrometer and if so, have you had recent luck in locating a vendor?  Thank you!
