Methylene Blue Stain – 5g (LR Grade)

Methylene Blue Stain is a widely used laboratory dye supplied in a 5g pack for educational science laboratories. Produced to Laboratory Reagent (LR) grade, this versatile stain provides reliable and consistent results for microscopy, biology, and introductory chemistry applications.

Identified by CAS No. 7220‑79‑3 and classified as Not Regulated for transport (UN: NR), methylene blue is easy to store and manage in school laboratory environments. It is clearly labelled to support safe handling in line with COSHH requirements and standard school science safety procedures.

Renowned for its strong blue colour and affinity for biological materials, methylene blue is commonly used to improve contrast when observing cells and microorganisms under a microscope, making it an essential teaching aid in life sciences.
