Handheld Microscope Users Guide
A. The Deep Well Slide
These plastic slides are perfect for use with the hand-held microscope! The depressed, circular
area in the center holds a few drops of water and other small objects, such as algae. It has a 1-
2mm thick ridge with a cover, so your organisms do not get crushed and the water does not spill
out! Organisms can live in a deep well slide for as much as a week, as long as the water does
not dry up and you have some plant matter inside of it to produce oxygen.
B. The Petri Dish Sandwich
Since not everyone has deep well slides handy, Petri dishes are a good alternative. You can
"sandwich" your specimens in between the cover and the bottom of the dish to create a slide.
Just place your sample (a few drops of pond water, onion skin, etc.) inside the lid of the Petri
dish. Then cover it with the bottom of the dish, creating a sandwich. There are small ridges
inside the lid of Petri dishes, so your organisms will not get crushed in this setup either. Care
must be taken when using a Petri dish, as water will spill out if it is disturbed.
