Methylene Blue USP 3% 3.75 mL – pharmaceutical dropper 💊

This concentrated 3% methylene blue solution in a 3.75 mL glass bottle with dropper is formulated for applications that require a small, high-purity dye or reagent. It suits laboratory spot tests, staining procedures, and other controlled uses where a pharmaceutical-grade liquid with verified absence of heavy metals and formaldehyde is preferred.

Key Points

The product is presented by METHYLENE BLUE CO as a compact, ultra-concentrated 3% solution in a glass bottle that includes a dropper for precise dispensing. According to the manufacturer, each batch is lab-tested and found free of detectable heavy metals and formaldehyde, and the formula does not contain stabilizers, dyes, preservatives, or fillers. The small-batch, hand-inspected production aims to ensure consistency across lots. Consider that concentrated dyes require careful handling and appropriate protective measures when used in lab or craft settings. 🧪

Technical Specifications

• Name: METHYLENE BLUE CO Methylene Blue USP 3% (3.75 mL)
• Concentration: 3% solution
• Volume: 3.75 mL
• Packaging: Glass bottle with dropper
• Purity: No detectable heavy metals or formaldehyde according to manufacturer testing

Benefits

Using a pharmaceutical-grade methylene blue with verified impurities removed can reduce the risk of interference in sensitive assays and visual artifacts in staining. The absence of added stabilizers or preservatives means the formulation is closer to a pure active substance, which can matter when reproducibility is important. The dropper bottle allows for controlled micro-dosing, which is helpful for titration-style applications or when small volumes are necessary.

Usage Recommendations

Handle the solution with appropriate personal protective equipment and work in a ventilated area. For laboratory staining, apply a few microliters as needed and avoid contaminating the dropper tip to preserve batch integrity. Dispose of any excess or waste according to local regulations for chemical liquids, and store the glass bottle in a cool, dark place to limit light exposure that could affect dye stability. 🧴

Note that while manufacturer testing reports no detectable heavy metals or formaldehyde, users requiring additional certifications or third-party analysis should consider independent verification. 🔬.
