Ideal for laboratory and field use, this apparatus allows the student to measure transpiration with minimal risk of breakages. The apparatus has only one glass component (the capillary tube) and is mounted on a strong backing plate. It consists of a capillary tube with millimeter scale connected via. 3 -way tap to a syringe. The cut shoot is connected to the third outlet. The apparatus can ...
For demonstration of transpiration rates and rates of water absorption by a cut shoot under various external conditions. A plant shoot is sealed into a stopper which fits the end tube and the whole apparatus is filled with water, the open end of the capillary tube, which is graduated in millimeter, dipping into beaker of water.
Suitable for individual student use, the cut shoot is attached to the side arm with tubing and the wide glass tube acts as the reservoir. Glass tube 160 x 20 mm., with side arm 8 mm. diameter. Capillary tube length 140 mm. with 1 mm. Bore.
For measuring the rate of uptake of water by a cut plant shoot. The apparatus consists of a central reservoir with a three whole stopper holding a capillary tube graduated in millimeters, a funnel with stopcock and a short length of 10 mm glass tubing, to hold the plant shoot.
Designed for demonstration of osmotic pressure at an elementary level in biology. A semi-permeable is attached to the wide end of a funnel having an indicator tube. The funnel is fixed in the reservoir, supplied with teat dropper pipette.
A complete unit, for comprising rates of absorption or revolution of gases by small organisms, during respiration, the apparatus consists of two boiling tube with stoppers connected by three way taps to either limb of a graduated manometer. One tube holds the organism and has a syringe for altering the level of liquid in the manometer during setting up.
For clinostat in place of the cork disc. A cylindrical aluminium vessel, 87 mm. and 100 mm. high. Holder accommodates any size or shape of pot up to 75 mm. dia.
For demonstration of heliotropism and geotropism. Germinating seedlings are pinned to the cork table which is rotated by an electric motor at 4 revolutions per hour. The motor is spindle mounted and may be clamped by a thumbscrew so that the place of the table can be set at any angle between horizontal and vertical.
