The PASCO Photosynthesis Tank PS-2521B is an ideal apparatus for studying photosynthesis and respiration in aquatic life. With this tank, students are able to measure the dissolved oxygen content of the aquatic plant environment and thus directly measure its photosynthetic activity. To control fluctuations, water in the outer tank is used. Turning the light on and off produces an easily interpreted graph in real-time, showing the relationship between light and the rate of oxygen production.

Typical experiments involving photosynthesis require students to infer photosynthetic rate changes by using chloroplasts and dye. Students can enhance their understanding of photosynthetic concentrations by using dyes as colored filters. The PASCO Photosynthesis Tank has been designed specifically to improve the measurement of oxygen in photosynthesis. Help students understand this concept more completely by directly measuring the production of oxygen.

The photosynthesis tank has two concentric Plexiglas chambers. This unique design allows students to control the environment without interfering with the measurements. In addition, the rubber stopper seals the inner environment so oxygen is not exchanged between the atmosphere and the sample. Two back-bored openings in the stopper form a tight seal with the sensors, but also allow for easy insertion and removal.

This product requires a PASCO interface and software, plus the PASCO PASPort Optical Dissolved Oxygen Sensor. We also recommend the PASCO Magnetic Stirrer for use with the Photosynthesis Tank. For more optional products, see the 'You Might Also Like' section below.
