No microscopic analysis work is possible without dyes, stains or indicators. Functionally, dyes and stains are extremely critical in biochemistry, molecular biology and microbiological research work, because they are often used to dye or stain certain cell components, protein, or DNA/RNA in order to visualize them.
In biochemistry and molecular biology work, dyes and stains are used to highlight biological tissues and to quantify or qualify presence of certain chemical substances when attached to substrates.

In microbiology, Dyes & Stains are used to make micro-organisms visible or differentiate them due to distinct staining properties. On the other hand, Indicators are often used to measure pH of samples. They are added to microbiological culture media to detect metabolic properties of micro-organims.

SRL has a large range of such specialized products which are best-in-class in its category, only with the highest quality, absorption capability and dye content.
