1% Methylene Blue - 30mL Microscopy Stain for Viewing Animal Cells and Bacteria

Methylene Blue (1%) is a widely used microscopy stain ideal for visualizing microscopic life in vivid color. Known for its attraction to acids, this stain effectively highlights cell nuclei, which contain deoxyribonucleic acid (DNA), making it particularly useful for observing animal cells. It also enhances the visibility of bacteria, which are naturally colorless and difficult to see, even under a microscope.

This 30mL bottle of Methylene Blue includes a convenient glass dropper for precise application.

Not for Human Consumption. For Laboratory and Educational Use Only.


Key Features & Benefits

  • Microscopy Stain: Highlights cell nuclei and bacteria with brilliant blue color.
  • Perfect for Animal Cells: Stains acid-rich structures like DNA-containing cell nuclei.
  • Ideal for Bacteria: Makes microscopic bacteria visible and easier to study.
  • Easy Application: Includes a glass dropper for controlled and accurate staining.
  • Non-Regulated: No special handling requirements for shipping or storage.

How to Use Methylene Blue for Best Results

Follow this simple step-by-step process to stain your microscopic specimens effectively:

  1. Prepare Your Slide: Create a wet mount slide with your specimen.
  2. Apply the Stain: Add 1 drop of Methylene Blue to one outer edge of the cover slip.
  3. Draw the Stain Under the Cover Slip:
    • Place a small piece of paper towel on the opposite edge of the cover slip.
    • The paper towel will draw the stain across the specimen using capillary action.
  4. Wait and Verify: Allow the stain to fully cover the specimen.
    • If necessary, add another drop of stain to ensure complete coverage.
  5. Observe Under the Microscope: Place the slide on the microscope stage.
    • The cell nuclei will appear as the darkest blue areas under the microscope.

Applications

  • Laboratory Use: Cell staining and bacterial visualization.
  • Educational Microscopy: Perfect for classrooms, biology labs, and science projects.
  • Professional Microscopy: Used in research to study cellular structures and microscopic life.

I like the mildly tart taste of this unflavored, unsweetened drink made up with water.
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I like the mildly tart taste of this unflavored, unsweetened drink made up with water. The texture doesn't bother me, with stirring right from the beginning of adding the water, there is no clumping. After 10 days there is no effect on my bowels which were regular previously anyway. My doctor wanted me to use this although I already have a high fiber diet.

Definitely Not Unflavored. This is Tart / Sour, Which Limits the Options to Certain Juices
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I was expecting an unflavored fiber powder. However, expect a sour/tart taste. This means you can't add it to tea or coffee. I don't think it is appropriate to say that it is "unflavored" as I've had psyllium husk from other vendors that are truly "unflavored" (i.e. no citric acid). Dextrin (another fiber source) is also unflavored. But this Metamucil is tart (like sucking a lime) and can only be added to tart juices like orange juice or lemonade.

Happy it is unflavored
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I was worried about the taste based on some of the reviews. I tried it in my coffee, and I'm glad I did it that way. I keep coffee in the fridge, so that is what I mixed with one tablespoon of this. I use half and half and no sugar. I tasted it. It tastes like burnt coffee. Not a bad thing...thats just what the taste it added. I decided to see what would happen if I added a splash of a flavored creamer. The taste went away instantly. Hope this helps someone!

Great for my tidy mind. Now the cabinet is organized and clean. Space saving too
Size: Left Facing, Size: Left Facing
Easy install. Glides nicely holds the jars without much movement. The labels are wonderful. I am super pleased. We bought 4 left facing for our cabinet. Not done replacing all the jars and such. But you can see a good idea how it will be. The fit out needs perfectly and looks great. I really like how neat and good visibility too. They seem sturdy with all the weight of the filled bottles also.

Great space saver, keeps everything organized.
Size: Left Facing, Size: Left Facing
I am soooo happy with this purchase! I’ve been researching lots of spice racks to see which ones would best suit my needs. This definitely fits the bill. This product was perfect. It includes everything you need to organize your spices: the rack, screws, stickers, bottles, and a white gel pen to write additional spice names. The rack is heavy duty and sturdy. Once anchored to your cabinet, there’s no way it’s falling out. The bottles are a good size and you can transfer standard store bought spices directly into the bottles. An additional asset is that the bottles come with a shaker spout that has two options for use. It can easily snap off and on when refilling. The stickers are well thought out. They’re good quality labels and can easily be repositioned. I accidentally had an edge stick to the middle of a bottle and was scared that it wouldn’t come off. I was happy that it lifted up cleanly and didn’t wrinkle the sticker. I didn’t have a need to write a lot of new names, except for two so far. Using the pen included, I wrote labels for Dashi and Seasoning-Arrachera. I tried to match the font of the labels and I think I did a pretty good job. You wouldn’t notice it was hand written unless you really stared at it. The white pen is great and so easy to write with. I didn’t have to go over any letters. One pen stroke was enough. It also came with labels that you can place on the side of the rack for easy identification. I haven’t put them on mine yet because I still need to buy two more racks to store all my spices. Then I can get them all organized the way I want. This is such a space saver. One of my absolute favorite purchases!
