Vivitar 40 piece microscope set shrimp hatchery instructions
1. To hatch the eggs, first prepare a brine solution. Pour the entire contents of a vial containing sea salt into a quart of
tap water. Add the brine shrimp eggs into the
solution. Allow the solution to stand at room
temperature (70 - 80F or 21 - 26C) for 24
to 48 hours and the eggs will hatch into nauplius larvae (this is the first stage of development after leaving the eggs).
2. Place some of the larvae into one of the compartments of the shrimp hatchery .
3. Place some fresh brine solution in another
compartment. Add a small amount of yeast to
this new solution. Then, using the eyedropper, transfer some of the larvae into this compartment as well. The yeast will
serve as food and produce oxygen for the larvae as they develop into maturity. Without food and oxygen, the shrimp cannot develop
and will die. Mature brine shrimp are known
as Artemia Salina.
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.
4. Observe the life cycle of the shrimp as they
grow: the dried eggs, the hatching eggs, the
developing larvae, and finally, the mature
5. The mature shrimp may be fed to fish in an
aquarium if you so wish. However, first
remove the shrimp from the brine solution
and place them into fresh water. An increase
in salt may harm the fish in the aquarium.
NOTE: Use the color filter especially when looking at clear or dim specimens.

Heraeus pico biofuge
Are you sure that the lid safety interlock switch isn't damaged/dirty? If the centrifuge can't detect that the lid is closed it will never start. Sometime it just needs an extra push down on the lid.

Premiere MS01u microscope bulb flickers. Won't come on.
It sounds like either the bulb is loose or the connection between the bulb socket and a wire is loose. To check both, Loosen the screw knob on the underside of microscope and open the panel to expose the bulb. Use a small screwdriver to loosen the screws holding (the two screws closest to the bulb) the prongs of the halogen bulb. Note that the prongs of the bulb are held in place by small brass plates which shift slightly when the screws are loosened. Remove the old bulb. Important: Do not touch the new halogen bulb with bare hands. Wear gloves or hold the bulb using tissue or lens paper. Body oils may damage the halogen bulb. Insert prongs of replacement bulb into top of socket (above the brass plate) and tighten screws slightly. (The brass plates will move up to hold the prongs in place.) Close door and hand tighten the thumbscrew knob.
If this does not work, contact Premier for assistance: Premiere® Microscope Service, 7241 Gabe Court, Manassas, VA 20109 (703) 330-1413
