AbstractPressurization of a Pasteur pipet for microscale chromatography is simplified by connecting a 20- or 30-mL syringe to the pipet using a length of Tygon tubing. This simple system allows the student to easily dry-pack a column using common chromatography packing materials. Results were uniformly good for introductory, organic, or upper-division research chemistry students.
