Contrast medium experiment with a blood vessel model

Principle:
When a blood vessel model is irradiated with X-rays, the blood vessels themselves are not visible at first. It is only after the injection of a contrast medium that the blood vessels become visible.

Determination of the Michaelis constant (with the Cobra3 Chem-Unit)

Principle

The enzymatic hydrolysis of urea in aqueous solution liberates carbon dixide and ammonia. The ions of these compounds increase the conductivity of the solution. Conductivity measurements can so be made to determine the rate of hydrolysis of urea by the enzyme urease ...
