Learn about the different pigments in plant material and how chromatography can help to separate molecules in a mixture.

Pink to bright rose color.
Characterized by cilia; nearly all possess two types of nuclei.

Cleans without leaving residue.

Examine the morphological characteristics of typical soil nematodes with the specimens in our well-populated culture.

Includes 500 ml each of buffer solution pH 10, pH 4, and pH 7. Also includes 100 ml of electrode storage solution, KCl.

Ideal for use as a model system, this free-living nematode has biological processes similar to those of other animals. The transparent animal normally inhabits soil.
