Measure transpiration rate or humidity with clever demonstration apparatus
Minimal glass components reduces risk of breakage
Great for studying essential plant physiological process
Includes instruction manual

Measure transpiration with minimal risk of breakages. The apparatus has only one glass component (capillary tube) which is securely mounted on a strong backing plate and printed with a 0-10cm scale. A cut plant shoot is inserted into an inlet tube, which is connected to a mounted syringe and capillary tube via a 3-way tap. The apparatus can also be used to measure humidity by connecting a porous pot to the third outlet. Size: 5.9"W x 3"D x 7.7"H.
