Edu science 600x microscope: no instruction manual and I cannot see anything through the lens (only a blurred blue light). What must I do to be able to see something ? Thx
Well I have the instruction manual, but it is not too helpful. When I was a child I put fleas and ants on the slides, but I guess this microscope is different. Here is what my manual says.
How to make a prepared slide: If the given sample is not thin and transparent, it cannot be observed by the microscope as the light from the reflector or the light source does not pass through it. Fibers, pollen, wool, or salt can be observed easily and a cover glass is optional. Clear samples are stained first with a drop or 2 of methylene blue, Eosin or other dying solutions (not included).
1. TEMPORARY MOUNT: Wipe the slide and cover glass clean. Slice a thin sample with the micro-slicer (blade is very sharp...adult supervision). Pick up the sample with tweezers and put it on the center part of the glass slide. Put one drop of water on the sample using the needle that came with your kit.
2.PERMANENT MOUNT:Proceed as above, however, before covering the slide with the cover glass, add a few drops of gum media (not included, available at the store) or Canada balsam solution or transparent adhesive glue with a disecting needle to the slide. Push down on the cover glass with the tweezers to fix it in place and leave to dry for a day.
VIEWING LIVE BRINE SHRIMP:
1.Pour a small amout of brine shrimp eggs into the petri dish.
2.Add enough water so that the eggs are submerged and add just a dash of table salt.
3.Place the petri dish in a well lit area (under a lamp with a 60 watt bulb is good, for 24 hours).
4. When you see movement in the petri dish place it on your microscope stage, turn on the light and watch the brine shrimp in action.
