Plant Enzyme Kit – Microzyme Phosphatase
This new kit was developed by SAPS (Science and Plants for Schools),
Homerton College, Cambridge, UK. The kit uses Microscience techniques to
help students understand the various factors that influence enzyme activi-
ty. Starting with Mung Beans, an extraction of Phosphatase is accomplished
followed by a series of semi-quantitive measurements. These include:
• Phosphatase activity
• Effect of pH on activity
• Effect of concentration on rate
• Effect of temperature (Heat Stability)
• Effect of time on product formation
• Effect of inhibitors on activity
Scope of delivery:
1 Comboplate®, 1 pack of pipettes, 1 spatula and forceps, 1 pH guide, 1 sy-
ringe (1 ml), 1x 1 ml syringe with adaptor (short length of silicone tubing),
10 micropipettor tips, 2 polypropylene microfuge tubes 1.5 ml) for centri-
fuging, 20 microfuge tubes for temperature studies.

Illumination Equipment for the Equipment Set
“Photosynthesis“
The illumination equipment serves as a source of light and a stand for
performing experiments regarding photosynthesis with the equipment set
9982-1012864.
Scope of delivery:
Laboratory lamp with power supply 12 V, 2.25 A, primary: 100 – 240 V,
50/60 Hz, tripod, plexi plate 150x150x3 mm, double socket
Photosynthesis Equipment Set
The equipment set can be used to observe the photosynthesis process and
establish the dependencies between light intensity, the wave length of the
light, the CO
2
content and other parameters. The equipment set is con-
ceived for use in school experiments, but can also be used for teacher-led
demonstrations. The CD-ROM included with the set contains extensive
teacher information with the theoretical background to each experiment
and an evaluation sheet (log) to be completed by the pupils.
Topics of the experiments:
• Proof of the oxygen produced by the plant
• The dependence of photosynthesis on light intensity
• The dependence of photosynthesis on light wavelength
• The dependence of photosynthesis on the CO
2
content of the water
• The dependence of photosynthesis on water temperature
• The dependence of photosynthesis on the number of the shoot sections
