ALDON Innovating Science Methylene Blue 1% Aqueous Solution, 1 fl oz (30mL) Dropper Bottle - Methyl Blue Microscope Stain - The Curated Chemical Collection

This methylene blue solution is excellent quality for various applications. The 1% concentration is properly prepared and consistent. The dropper bottle design makes precise dispensing easy and prevents waste. I use this for staining specimens for microscopy work and it performs perfectly every time. The solution has good color intensity and stains reliably. The 1 fl oz size is practical - enough for numerous applications without excess volume that might degrade before use. The bottle is well-labeled with concentration and safety information. The dropper tip provides good control for adding exact amounts. I appreciate that this is properly formulated for scientific use rather than a questionable generic solution. The solution remains stable and doesn't show signs of degradation or precipitation. Whether you're doing microscopy, aquarium applications, or other uses requiring methylene blue, this is a reliable product. For hobbyists, students, or anyone needing quality methylene blue solution, this offers good value and proper formulation. The packaging protects the solution well during shipping.

Saved me a fortune on my sick fish tank

Good , i drink it

Good product

Haven’t used it yet but arrived on time and looks great

I used this stain for both cheek cells and onion root cells in my high school biology classroom. It was good quality and worked as expected, but was WAY cheaper than ordering from Carolina Biological or Flinn Scientific, and it arrived way faster. The blue was a nice color as seen in the picture. It stained the nuclei nicely.

Warning. May Be Harmful if Swallowed (see photo). If you're buying this for something other than your fishtank, beware. Value for money: One of the least expensive, but...

Worked as promised. Used in a lab with my middle schoolers to identify organelles within their cheek cells.
