1- Our lab uses hot plate for embedding, which is bought in 1980
(manufactured in Russia). It still works OK.
We have not embedding centre.
2- I itself prepare hematoxylin from Aldrich's powder by Lillie's
recipe at each 2 weeks already many years with high quality staining.
This is a progressive stain. Process of the preparation takes
20 minutes and we have always fresh hematoxyline.
