Electric Generator
Attach this functioning electric generator to a steam engine (AP5718) and amaze
your students as you convert steam power to electrical power. The included drive
belt is easily attached to the flywheel of the steam engine and starts generating
power instantly. The steam engine will generate enough energy to light the attached
lightbulb. Some assembly required. Engine and generator must be mounted to a new
base, such as a wooden board.

Calorimeter, Foam
By: The Flinn Staff
The thick walls and lids make these calorimeters
more effective than ordinary foam drinking cups by preventing heat loss in all directions.
Their wide, stable base prevents tipping when mixing with a magnetic stir bar.
Use a sharp knife to cut the foam lid to fit any thermometer. 900 mL capacity. Sold
in packages of two.

Calorimeters, Small-Scale
By: Walter Rohr, Retired Chemistry Teacher
The perfect small-scale calorimeter! These high-quality, 2"-thick polystyrene
calorimeters allow for quantitative thermodynamics experiments with only 15
mL of reagents. Smaller amounts provide faster results so several trials can be
completed in a single class period. A specially formulated coating permeates the
pores of the foam to prevent water absorption and maximize heat efficiency. The
calorimeter constant and the calorimeter’s mass will remain the same for the
entire experiment! An Introduction to Small-Scale Thermochemistry lab manual
(AP5912) provides excellent hands-on experiments that utilize the full potential of
these calorimeters (sold separately).

Calorimeter,
Economy Choice
By: The Flinn Staff
Here it is—the easiest and most inexpensive way to determine the caloric content
in solid foods. For instance, to determine the number of calories in a peanut, simply
suspend a flask containing 50 mL of water in the calorimeter, place a peanut of
known mass beneath the flask and ignite it with a match or lighter. The released
energy from the burning peanut heats the water in the flask. Once the flame burns
out, students measure the increase in water temperature and the decrease in mass
of the peanut to calculate the caloric content of the peanut. Multiple trials can be
performed in just one class period. Kit includes calorimeter chamber, flask and
detailed laboratory instructions.
Note: Solid food items like peanuts or cracker pieces are needed.

Calorimeter, Aneroid, Dry
A specially insulated outer wall makes this quality calorimeter five times more sensitive
than traditional instruments. It is constructed of an aluminum inner cylinder
surrounded by a thick layer of styrofoam insulation, then enclosed in a durable
plastic case. This special design results in minimal heat loss. Accepts Specific Heat
Cylinders (AP6112).
