Without the oil, the refractive index will be incorrect. Don't the microscope science kits you can buy for kids educational toys contain a variety of stains ready to use? Yes realise that. The 100x objective is oil immersion and with a 10X ocular gives 1000x magnification. Sorry I gave the magnification of the objective lenses instead of total magnification. Some kids microscope sets have simple stains but not really suitable. I want to make Loffler's Methylene Blue which when ripened give a polychrome stain forming a violet compound with polychrome qualities. I am also interested in Algae, Protozoa and diatom specimens. |

| 559972 | 2007-06-19 12:01:00 | Thanks all. Very informative. I am making Methylene Blue stain to be able to see those little nasties. Anybody out there interested in microscopy ? You can get methylene blue at some aquarium / pet stores. It's used because it's tozic to many disease microbes but relatively harmless to Nitrobacter & Nitrosomonas which are required for aquarium filtration. Be careful with this stuff. A single drop of 5% solution in a cup of water can stain the bathroom sink blue for weeks! I know as I did it several times. The first was an accident, while the second was to see how strong it had to be to stain :D P.S. If you see an aquariast with blue seals on their tanks, now you know why! |

| 559973 | 2007-06-19 13:24:00 | I have a recipe for a microscope stain which requires an item 95% ethanol. Any chemistry students out there who can tell me what it is and where to get it. well i know of a particular drink that you can get about that strong smells like licorice and tastes like burning:lol: good ol' Absinthe:D fun night, what i can remember of it |
