Chromatography—Laboratory Kits
Introduction to Paper Chromatography—
Student Laboratory Kit
By: The Flinn Staff
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 has a different molecular structure and, usually, a different polarity. A lot of “great science” will be learned in this activity. The second experiment involves the separation of pigments found in plants. Using fresh spinach leaves students sepa- rate out four to five different pigments responsible for photosynthesis. These pigments are identified by their colors and relative position on the chromatogram. A great activity to introduce the relationships between chemistry and biology. Lab instructions include a detailed explana- tion of chromatography, student-friendly instructions and helpful tips. Chromatography pens, paper and wood splints are included.
Complete for 24 students working in pairs. Super Value Kit is complete for 5 classes of 30 students working in pairs.
Chromatography Challenge—Science,
Inquiry, and Art—Guided-Inquiry Kit
By: The Flinn Staff
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 using radial paper chromatography and a variety of black mark- ers. Students will be amazed at the unique art chromatograms that can be made. An excellent activity to teach compounds and mixtures, the separation of mixtures, and the principles of chromatography. Includes detailed instructions with reproducible student handouts, valuable Instructor’s Notes, and a page of beautiful color photos of sample art.
Complete for 90 radial chromatograms. Includes one set of eight markers. Additional sets of markers are available separatSelTy.EM
