Dear business partner,

We would like to inform you about the change in the composition of the reagent Hematoxylin, Weigert A. The modification resulted in a change in labeling, i.e. the symbol of mutagenic effects on germ cells and
carcinogenicity both during the production of the reagent and for the end user was removed. Accordingly, labeling on both the reagent and the kit box is changed, starting with the product batches indicated in parentheses below;

Hematoxylin, Weigert A (HEMA-25/24)
Hematoxylin W kit (HEMW-38/24)
Martius Scarlet Blue (MSB) kit (MSB-33/24)
Masson trichrome kit (MST-113/24)
Masson-Goldner trichrome kit (MGT-59/24)
Mucicarmine kit (MUC-48/24)
Van Gieson Trichrome kit (VG-40/24)
Weigert-Van Gieson kit (WVG-44/24)

Updated Safety and Technical Data Sheets of the above listed products are available for download on
BioGnost’s website.

The appearance and performance (functionality) of the reagent remained the same compared to the previous variant, which was verified through testing.

Feel free to contact us should you require further information.
