How do respirometers work
WebCarefully immerse all six respirometers in their waterbaths. DO NOT touch the respirometers once the experiment has started! Let the respirometer equilibriate for another 5 minutes before preceding to step 16; 16. Read all of the respirometers to the nearest 0.01 mL and take the temperature of each waterbath. WebDec 7, 2024 · How do Respirometers work? Respirometers measure the amount of oxygen we inhale and exhale. They measure the amount of carbon dioxide in our exhaled breath. Like the carbon dioxide concentration, the amount of oxygen we need to breathe is referred to as the arterial oxygen saturation or SaO2.

WebPlace one set of respirometers into the room temperature water bath and the other set in the ice water bath. Elevate the respirometers by setting the pipettes onto masking tape and allow them to equilibrate for five minutes. Next, lower the respirometers into the water baths and take reading at 0, 5, 10, 15, and 20 minutes.

WebRespirometry is a general term that encompasses a number of techniques for obtaining estimates of the rates of metabolism of vertebrates, invertebrates, plants, tissues, cells, or microorganisms via an indirect measure of heat production ( calorimetry ). WebIt is a closed chamber respirometer requiring only small (20ml) samples of activated sludge. By using multiple electrodes and dedicated software, respiration rates can be measured in only 5-10 mins. All of the time-consuming aspects of respirometry have been removed.
