[. . . ] Instruction Manual Meade 900X Microscope 2 Your new MEADE 900X Microscope is a doorway to new and exciting adventures and is designed to bring hours of enjoyment, wonder and just plain fun. . . discover the hidden microscopic world around you!Before trying out your new equipment, please take the time to read the important Cautionary and Safety information below. CAUTIONARY STATEMENTS NOTE: This set may include chemicals that could be harmful if misused. This also contains instruments and other materials with sharp points and edges. [. . . ] 1) and slowly turn the focus knob until the specimen can be seen in focus. Adjust the mirror or light source to provide the amount of light that gives you the best image. Look in the eyepiece and observe what happens to the image when you move the slide from side to side and up and down. If you wish to increase magnification, rotate the objective turret to a higher power and refocus. Below the stage, a fitting will line up with the opening in the center of the filter. Remove the filter, turn it around 180°, and reinstall it onto the stage. 4 NOTE: The view presented in the eyepiece is upside-down and reversed from left to right of the object. In other words, if you wish to examine more of the left side, move the slide to the right. Or if you wish to examine more of the top of the image, move the slide down-- and vice-versa. CAUTION: When you are finished observing, be sure to turn the light source around, if necessary, so that it turns off and doesn't wear down the batteries. Remove the batteries before storing the microscope for a month or longer. Fig. 5 8 NOTE: Use the color filter especially when looking at clear or dim specimens. ors are available in this position. Install the filter as described above and turn the light source (U, Fig. Rotate the filter and see how the filtered light enhances the image of the salt or sugar. The Brine Shrimp Hatchery Brine shrimp are tiny crustaceans that are ideal for study with a microscope. Your microscope kit comes supplied with sea salt , brine shrimp eggs (G, Fig. The brine shrimp eggs included with this set are dried and will remain alive for up to five years if stored in a cool, dry place. Allow the solution to stand at room temperature (70° - 80°F or 21° - 26°C) for 24 to 48 hours and the eggs will hatch into nauplius larvae (this is the first stage of development after leaving the eggs). Place some of the larvae into one of the compartments of the shrimp hatchery (M, Fig. The yeast will serve as food and produce oxygen for the lar- 9 vae as they develop into maturity. Note: Using an eyedropper with just the right pressure to get a desired amount of liquid onto a slide can be harder than it looks. Take out a clean slide and practice squeezing a drop of water onto the slide until you feel comfortable that you can control the size of the drop that you're squeezing out. Observe the life cycle of the shrimp as they grow: the dried eggs, the hatching eggs, the developing larvae, and finally, the mature shrimp. [. . . ] When the slide is dry, use the eyedropper to place one drop of eosin (F, Fig. Perform this operation a few times to clean out all the eosin from the eyedropper. Tilt the slide from side to side to spread the stain over the specimen. To flush away the excess stain and to stop the staining action, hold the slide at an angle over 13 the waste cup. [. . . ]
