There are four preservative formula under Kaiserling's name. Two of these (Kaiserling I and II) are used sequentially for the preparation of medical museum displays. The other two are general preservative solutions, although all four may be used for that purpose.
It is not an uncommon practice to substitute 10% formalin for Kaiserling I as it does much the same job, although tissue must be left in it for fixation to be complete – a few months at least. One effect of using either 10% formalin or Kaiserling I is that the natural colour is lost during fixation. This may be restored in two ways:
For those interested in this procedure please consult a text on medical museum technology. It is outside the scope of StainsFile
