About This Product
This bottle-type potometer is used in plant physiology lessons on water uptake. The stem of a cut shoot passes through the hole in the rubber stopper into the wide-mouth bottle, and the movement of water in the narrow-bore bent glass tube is read against the 0 to 30 cm scale. The dropping funnel fitted in the stopper is used to add water to the bottle.
Frequently Asked Questions
What range does the scale cover?
The narrow-bore bent glass tube is clipped to a scale reading 0 to 30 cm with 1 mm divisions.
Where does the plant go?
The rubber stopper has a hole that takes the stem of the plant, so the cut end sits in the water inside the wide-mouth bottle.
