Introduction
The PS-2521A Photosynthesis Tank is designed for use with
either PASPORT or ScienceWorkshop sensors. Although the
basic Photosynthesis experiment can be accomplished with
test tubes, as described in the Dissolved Oxygen Sensor
Manual, the Photosynthesis Tank allows for greater flexibil-
ity when conducting this important experiment.
In a typical experiment your primary sample (such as elodea)
and water are placed in the inner chamber. the size and shape
of the inner chamber can accommodate a stirring bar and
other biological samples in addition to your primary sample.
The outer chamber is used to regulate temperature and/or
add chemicals that filter the incoming light, without directly
affecting the sample. the large rubber stopper is used to iso-
late the micro-environment of the inner chamber while
accommodating a Dissolved Oxygen Sensor and a Tempera-
ture Sensor. If one or both sensors are not in use, the
included #3 rubber stoppers can be used to seal the sensor
port. An unused port can also be used to introduce chemicals
to the primary sample during an experiment.
Warning
• Although the Photosynthesis Tank is specifically
designed for PASCO sensors, extra care should be taken
when inserting the Dissolved Oxygen Probe to prevent
any damage to the probe membrane.
