Chromatography Stand

This is a 3D-printed stand designed for paper chromatography experiments.The top frame has narrow slots—each less than 2 cm wide—to hold the strips of chromatography paper securely in place.The overall height of the stand is about 15 cm, allowing the paper strips to hang freely and dip into the solvent at the bottom of a container.Its open design keeps the papers separated and stable, making it easy to observe the upward movement of the solvent front during chromatography.
