Safranin O 1%, aqueous (SAFELINE) is a chemical solution characterized by its ease of use and low hazard. It consists of aqua dist./VE water and the dye Safranin O and belongs to the SAFELINE product line, which is particularly suitable for use in schools and by private users.

As an integral component of staining kits such as AAS - Astrablau-Auramin-Safranin and AS - Astrablau-Safranin, this solution has a wide range of applications, especially in medical diagnostics and histology. Here it is used for staining and contrasting cellular components.

Safranin O, known by the C.I. number 50240, consists chemically of C20H19N4Cl. Together with aqua dist./VE water (CAS No. 7732-18-5), it produces a solution that has an affinity for certain cellular components. This results in enhanced visualization of these cellular components.

Scientific laboratories also use this solution to achieve detailed and high-contrast visualization of cellular structures. This supports precise analysis and identification of tissue components.
