Chemiluminescence
Explain and view chemiluminescence!
Observe how luminol is converted to an
excited state in the presence of an oxidizer
such as hydrogen peroxide. As the excited
state molecule decays or returns to the
ground state, energy is produced as light.
Includes 100 ml of luminol solution and 50
ml of 6% solution of hydrogen peroxide.
Grades 6—12. Sh. wt. 0.69 lbs.

Spectrophotometer
This simple, practical laboratory instrument is precisely designed, ruggedly built, and
easy to use for general analysis and experiments. It features a large screen graphic
LCD that gives you clear, quick, and accurate readings in absorbance and transmittance.
The sample compartment accepts both round optical glass or square, 10 mm
path length cuvettes. The built-in secondary optical filters reduce stray light and
increase precision. This unit has a wavelength range of 350-1,000 NM with a bandwidth
of 10 NM. Includes a 1⁄2" round tube holder, 3⁄8" square cuvette adapter, box
of 12 round optical glass cuvettes, USB port, dust cover, and manual. 90-240V AC,
50-60 Hz. Shipped directly from factory. Allow extra delivery time. Sh. wt. 15 lbs.
