Accurately determine the melting temperature of a solid.

Although bacterial viruses, or bacteriophages, are present in many natural environments, they cannot survive autonomously. They require a host cell to reproduce and survive. In this experiment, students will learn about the different life cycles of bacterial viruses. They will then perform a viral plaque assay to indirectly visualize the viruses and to determine viral titer and multiplicity of infection (MOI).

Determine the Amount of Nitrogen in Water Samples.

With this kit, students determine dissolved oxygen concentration without a meter.

Use Color Transition of Titration to Determine Water Hardness.

This kit allows analysts to perform a very simple titration to determine the alkalinity and the phenolphthalein of their fresh water sample.

Versatile, easy to use, and compact precision instrument for measuring α-, β-, and γ-radiation.
