Carolina® Volumeter/Respirometer



Newly updated, this volumeter's unique design makes respiration experiments a gas!

This apparatus is sure to set the standard for ease of use, data reproducibility, and value. Easy to set up with no loose lines or awkwardly placed tubes, it is sleek, compact, and provides an airtight closed system that is simple to manipulate and generates easily read data. Ring stand compatibility makes photosynthesis and temperature-controlled experiments a cinch. This hands-on apparatus is ideal for studying metabolic rate and oxygen consumption in plants and animals such as crickets, mealworms, elodea, and germinating peas. Dye indicator effortlessly adjusts to zero for easy data gathering without disturbing experimental setup. Detailed teacher's manual includes sample data, teacher tips, and reproducible student guides. Designed for use as a teacher demonstration or a small group activity.
