DNA MOLECULE CONSTRUCTION KIT (3003)
Quite different from the conventional models. This unique plastic model provides easy assembly of the model and then twisting it into a double helix, instead of building it around a center post as in other conventional models. Each of the four nitrogenous bases comes in a different unlabeled color, so the students can design their own base pair coding. The model is removable from the plastic base and can be extended to its full length to demonstrate standard separation with numbered Key Card.

PARAMECIUM (3005)
Comprise two detailed, descriptive, accurate and complete models combined in one and mounted on a common base. Provides the overall view of Paramecium, magnified about 1600x. The stand mounting of the model allows convenient viewing by a group of students, even at a distance. The model is sectioned longitudinally, the outer half can be detached to reveal macroand micronuclei, a contractile vacuole, membranelles, myonemes, neuroneme network, food vacuoles, and formation of endo and ectoplasm. The second model, the pellicle enlarged 6,500x, facilitating an upclose view of trichocysts and ciliary bending action illustrating a metachronal wave. The pellicle is mounted directly on the base, while the paramecium is mounted on the stand with numbered Key Card.
