Methylene blue 2% in pharmaceutical quality: high-purity solution for technical, scientific and industrial applications, laboratory tested and without impurities. This formaldehyde and alcohol free formula provides maximum purity and stability for precise, reliable laboratory and industrial applications. The UV-protected glass bottle preserves the quality in the long term and reliably protects the solution from light and external influences. Due to the intensive blue colouring, the product is ideal for analytical processes, dyeing processes and chemical applications. The pipette allows precise dispensing, reduces waste and ensures easy and controlled handling. Methylene Blue 2 % USP quality is an ultra-pure, third-party-tested aqueous solution produced under GMP conditions and entirely free of formaldehyde, alcohol, and any detectable contaminants. Engineered solely for technical, scientific, and industrial use, the deeply pigmented, water-soluble dye excels in microscopy, redox titrations, analytical quality-control tests, and a broad range of laboratory or process-control workflows where intense, stable coloration is essential. Every batch is filled into a 3.4 oz / 100 ml UV-shielding amber-glass bottle that blocks more than 99 % of incident light, safeguarding the solution against photo-induced degradation. The accompanying precision dropper permits micro-accurate dosing, minimizes waste, and keeps workspaces clean, allowing users to dispense exactly the volume required for each procedure. Multi-stage filtration and purification eliminate particulate matter and heavy-metal traces, while each bottle is shipped with a lot-specific Certificate of Analysis and a current Safety Data Sheet to guarantee traceability and consistent quality. The formula remains stable under normal storage conditions, resisting discoloration, crystallization, and oxidative breakdown, so professionals can rely on reproducible results over an extended shelf life. Thanks to its high chromatic density, the solution delivers sharp contrast on slides, membranes, and textiles, supporting clear endpoint detection and vivid staining in controlled laboratory or industrial environments. Despite its versatility, this product is neither intended nor approved for oral ingestion, parenteral administration, veterinary treatment, or diagnostic use. It must be handled exclusively in accordance with local chemical-handling regulations, with appropriate personal protective equipment and reference to the supplied SDS. Manufactured to exacting standards, Methylene Blue 2 % offers scientists, technicians, and engineers a dependable, contamination-free dye that unites purity, stability, and ease of use in a single, UV-protected package—ensuring precise, repeatable performance whenever rigorous technical accuracy is required.
