Differential Model, permits the instructor and student to manually turn the handle and apply a load to the transparent wheels to demonstrate the differential mechanism, permits power from the engine to be transmitted to a pair of driving wheels.
Diffraction Apparatus, Used to map light intensity versus position for many-slit geometries, Slits are made by depositing metal film on glass, creating extraordinarily clean slits with fully opaque blocking areas.
Diffusion and Osmosis kit, Includes: Agar, Bromothymol blue concentrate, Hydrochloric acid, Plastic cups, knives, stirrers, Cork borer Dialysis tubing, Microscope slides, Coverslips, Sucrose, Ovalbumin, Sodium chloride, Glucose QuickSolution, to study movement of water
Digital Counter For event counting, a fixed counting period can be programmed in a range from 0.1 ms to 99999 s. Counter events (e.g. start or stop) can either be triggered by a signal to the input sockets or manually via switches. The unit includes a plug-in power supply.
Nexpensive, compact counter for measuring milliseconds. Each count is started and stopped by a signal at the input sockets. The device is automatically reset to zero each time it is restarted.
