I think it is the equivalent of Steedman's solution. I don't have the precise formula to hand but I know it contains a formaldehyde.

Subject: Re: Best way to preserve small shark specimens
Hi Tammy,
Re this ‘preserving fluid’ you have, do you have any idea what it comprises, also does it have a vinegary smell by any chance? The latter may be Kaiserling’s preservative. But there is also Wentworth’s colour preserving technique.
Ideally, frozen specimens should go into some formalin-based fixative first
With all good wishes, Simon.

Dear all,
I am hoping for some advice. A colleague has some frozen specimens of small deep-sea sharks. We would like to make these available for use in teaching and therefore have decided they would be best moved to jars of preservative fluids. In the past I know we have used a solution called 'preserving fluid' which allows us to retain the dark colouration in such specimens (avoids the bleaching effect that ethanol has). However I wonder if there are any other techniques we should consider? Do I need to do anything other than defrost the specimens and move into the preserving fluid?
Thanks for any advice.
Tammy
