Students learn the fundamentals of paper and thin-layer chromatography (TLC) as they answer the inquiry question, “What colors my food?”
Introduces students to ink chromatography and its application in solving forensics cases.
Used in chromatography studies. United Scientific Supplies Chromatography Strips are 15 x 2cm in size.
Transparent Spotting Guide may be used with plates up to 20 x 20 cm. The guide rests above the surface of the plate without contacting the adsorbent layer, avoiding damage to the layer. It accurately positions micropipettes and syringes, even when the plate is removed for drying between applications. The metric scale on the Spotting Guide facilitates reading of Rf values. Standard area circles of 3 to 255 mm2 aid in estimating spot sizes.
Isolate a carbohydrate-binding lectin protein from an extract of jack bean meal.
Purified fractions of DNA and RNA are analyzed by agarose gel electrophoresis.
Are you planning a virtual curriculum or looking for experiments ideal for distance learning? With the MyLab™ Custom Kits, you can easily plan your curriculum. Each kit comes with instructions and materials for 2-3 runs of each experiment.
Learn the principles of ion-exchange chromatography.
Students perform paper chromatography on three dyes, a dye mixture, and determine the mixture's composition
In this activity, students will perform a paper chromatography experiment on three known amino acids, and then use their results to identify the components of an unknown amino acid mixture.
Uses paper chromatography to separate various pigments from a sample of plant pigment extraction
In this experiment, students become medical researchers and investigate the chemical contents of three simulated e-liquids using thin layer chromatography.
Investigate the oldest documented technique used to separate chemical substances.
See that commercial food colors contain more than meet the eye.
Develop understanding of thin layer chromatography, use Rf values to establish standards and use Rf standards to identify 'unknowns'.
