Micro Respirometer Manufacturer,Supplier and Exporter in India
Product Code : EL-CL-12655
Jlab Export is a leading Micro Respirometer Manufacturer,and suppliers in India
Micro Respirometer (code EL-CL-12655) is a board-mounted apparatus, 400 × 150 mm, for studying gas exchange during respiration: it measures the oxygen taken up by a small organism and, from a second run, the carbon dioxide it gives out. A rod on the board fixes it to a retort stand. JLab manufactures the micro respirometer, model JLG368/040, in Ambala, India.

How the Oxygen Reading Works
The organism, such as germinating seeds or small insects, is enclosed with potassium hydroxide or soda lime, which absorbs the carbon dioxide it breathes out. As the organism uses oxygen, the volume of gas around it falls, and the coloured liquid drop that serves as the marker moves towards the organism. The distance the drop travels in a timed interval shows the rate of oxygen uptake. Keep the absorbent from touching the organism, as potassium hydroxide is caustic.
Finding the Carbon Dioxide Given Out
Repeat the run with water in place of the absorbent. The drop now moves only by the difference between the oxygen used and the carbon dioxide released, so subtracting this reading from the first gives the carbon dioxide evolved. Dividing carbon dioxide by oxygen gives the respiratory quotient. Hold the temperature steady during both runs, since warming or cooling also moves the drop; a control with glass beads in place of the organism shows any drift.
