Product Details

A fantastic, yet inexpensive method of teaching column chromatography. Column liquid chromatography is used in industry to separate mixtures and detect trace components of a mixture. The Sep-Pak cartridge is filled with a solid nonpolar material that helps to separate components of mixtures. Sep-Pak cartridges are reusable if cleaned and stored properly after use. With each Sep-Pak purchase, you will receive instructions for separating the red and blue dyes in a grape-flavored drink (10-mL or 12-mL syringe required).

Performance Expectations

MS-PS1-1. Develop models to describe the atomic composition of simple molecules and extended structures.
MS-PS2-3. Ask questions about data to determine the factors that affect the strength of electric and magnetic forces
HS-PS1-3. Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
HS-PS3-5. Develop and use a model of two objects interacting through electric or magnetic fields to illustrate the forces between objects and the changes in energy of the objects due to the interaction.
