All SPI-Chem stains for light microscopy are certified to be of the highest quality and purity commercially available and are manufactured to rigorous standards.
Just who uses these stains? Actually a wide range of laboratories. For those in histology using "H & E techniques", or Hematoxylin and Eosin techniques, the SPI-Chem products are quite acceptable. The nuclei come out dark blue and the cytoplasm and nucleoli, red.
Our customers have the choice of purchasing their stains and dyes either in dry powder form or they can take advantage of the convenience of ready made solutions.
