AP7174 - $42.95
Black is the absence of color—or is it? The challenge in this inquiry-based activity is for students to reproduce beautiful multicolor art patterns created by the teacher using radial paper chromatography and a variety of black markers. Students will...
AP7199 - $83.15
Visualize the properties of amino acids using paper chromatography! The properties of amino acids—acidic or basic, polar or nonpolar, ionic or neutral—are enormously important. They dictate the structures of proteins and the catalytic activity of enzymes....
AP4503 - $64.75
Paper chromatography is fun! In this unique kit, students conduct two paper chromatography experiments. The first lab involves the separation of pigments from different inks (marking pens). Many inks are mixtures made up of several pigments. Each pigment...
AP4847 - $66.70
You are what you eat! Many vegetables contain carotenoids, chlorophylls, and other pigments which contribute to their characteristic color. Pigments such as ß-carotene make vegetables “good for us.” In this kit, students will extract pigments from...
AP8687 - $59.10
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 these mixtures. This kit incorporates...
AP4504 - $104.25
Separate complex organic molecules using thin-layer chromatography (TLC). Our simple, inexpensive, and easy-to-use lab activity clearly illustrates for students the principles of thin-layer chromatography. Best of all, we know you'll be pleased with...
AP5992 - $57.65
Perform chromatography separations using the chromatography centrifuge—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...
FB0586 - $61.60
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 different plants. This kit makes it easy to set up...
AP8686 - $102.45
Similar to our radial chromatography kit (Catalog No. AP8687), but using a technique that runs the chromatograms directly onto T-shirts. The process is fast, easy, safe, and it produces beautiful explosions of color. Let chemistry make the fashion...
AP7392 - $61.15
There is more to spinach than meets the eye! A green leafy vegetable, spinach contains iron, chlorophyll, and several other pigments. Students are guided in the use of basic column chromatography techniques to find and identify these accessory pigments...
AP7394 - $45.20
Food dyes have been used extensively for more than 100 years. Would you eat maraschino cherries if they were their natural color of beige instead of red? Explore the properties of the seven Food, Drug, and Cosmetic (FD&C) artificial food dyes with...
AP7405 - $78.10
Are any other acids found in fruit juices besides citric acid? Some edible fruits contain six or more carboxylic acids, including benzoic and traces of oxalic. How are these acids separated and identified? Thin layer chromatography, or TLC, is a quick...
AP7524 - $64.95
Have your students perform paper chromatography using metal ions! In this kit, students learn more about the basics of paper chromatography by developing and evaluating their own chromatograms. Students determine the components of an unknown solution...
AP7501 - $66.15
Caffeine is a naturally occurring heterocyclic molecule called an alkaloid. Alkaloids contain at least one nitrogen with lone pair electrons, giving them their characteristic basic property. Caffeine is found in the seeds, leaves, and fruits of many...
AP7605 - $127.95
Paper chromatography is fun! In this unique kit, students conduct two paper chromatography experiments. The first lab involves the separation of pigments from different inks (marking pens). Many inks are mixtures made up of several pigments. Each pigment...
AP7661 - $60.20
Big Idea 2, Investigation 5, Primary Learning Objective 2.10 The entire palette of artificial food colors is derived from just seven dyes certified by the FDA for use in food, drugs, and cosmetics. How can these FD&C dyes be identified in a mixture?...
