Plant Pigment Chromatography—
Student Laboratory Kit
By: The Flinn Staff
Provide your students with an exciting method to study and compare plant pigments. Using thin-layer chromatography, students can separate and compare chlorophylls and accessory pigments found in two differ- ent plants. This kit makes it easy to set up, perform this interesting experiment and get terrific results in a single class period. Perfect for biology, botany and environmental science students.
Complete for 30 students working in pairs. Perform this experiment in a fume hood or well-ventilated lab.
Chromatography Centrifuge—
Student Laboratory Kit
By: Jeff Bracken
Westerville North H.S., Westerville, OH
Perform chromatography separations using the chromatography centri- fuge—it’s fast, easy and fun! Simply spot the water-soluble inks on the absorbent paper, place the paper on the motor, and turn it on. Within seconds the spinning disk separates the various ink mixtures into bril- liant patterns. Teach the concepts of chromatography, separation of mixtures and physical properties with this unique kit! Includes two Bracken’s Demonstration Spinners, 100 sheets of absorbent paper and 30 Beral-type pipets.
Complete for 30 students to perform at least three separations each. Water-soluble pens are required and available separately. Additional spinners (Catalog No. AP6202) are also available.

Radial Chromatography— Chemistry with an Artistic Flair! Super Value Laboratory Kit
By: Bob Becker
Kirkwood H.S., Kirkwood, MO
Black inks used in commercially available pens are often mixtures of several pigments, and each pen company usually has its own unique, patented “recipe” for black ink. Paper chromatography can be used to separate the ink mixtures.
This kit incorporates a simple technique in which the solvent moves out radially from a central point. This produces remarkably beautiful circular chromatograms in just minutes. Through a series of hands-on activities, students can exercise their artistic creativity while learning the basics of chromatography. Includes all necessary materials and an assortment of eight water soluble black markers that each produce unique, colorful patterns.
Super Value Kit is complete with enough materials for 180 12.5-cm chromatograms, plus 10 extra-large, demonstration-sized (24-cm) chro- matograms. Additional sets of black markers are available separately.
