Product Details

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 various ink mixtures into brilliant 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 required and available separately. Additional spinners (Catalog No. AP6202) are also available.

Performance Expectations

MS-PS1-4: Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.
MS-ESS2-6: Develop and use a model to describe how unequal heating and rotation of the Earth cause patterns of atmospheric and oceanic circulation that determine regional climates.
HS-ESS2-3: Develop a model based on evidence of Earth’s interior to describe the cycling of matter by thermal convection.
