Dyes and stains

chaptec  manufactures a range of laboratory-based stains and a buffer solution available in ready-to-use solutions, including:

  • Spanish saffron (alcoholic solution)
  • Phloxine B (aqueous solution 1% W/V)
  • Tampon PBS (concentrated solution)

Spanish saffron (alcoholic solution)

This yellow acidic alcoholic dye is used in trichromatic staining methods or when routinely staining with HPS (hematoxylin, phloxine, saffron). It is a regressive dye that requires overcolouring followed by differentiation with alcohol.

Phloxine B (aqueous solution 1% W/V)

This dark pink acid dye is mostly used as a cytoplasmic dye in routine HPS colouring. It attaches to dense acidophilic structures such as connective tissue, red blood cells and elastic fibres. It is a regressive dye that requires overcolouring followed by differentiation with water.

Tampon PBS (concentrated solution)

Designed for immunohistochemistry techniques, the PBS buffer is used to dilute antibodies and wash the slides. It is available in concentrated solution, in containers of 132 ml for 4L of preparation; pH of 7.2 + 0.2.

Our dyes show remarkable results in terms of clarity and cellular clarity, with beautiful contrasting colours.

Each batch is tested by external laboratories to ensure consistent high quality for all histological procedures.
