Dr FuelCell fuel cell car, basicThis fuel cell car set contains an electrolysis unit that is reversible and can thus both function as an electrolyzer that generates hydrogen, and which can subsequently function as a fuel cell that generates electricity to drive the electric motor in the car. Also included is a bottle of distilled water , a solar cell and a stopwatch, as well as a manual with various tasks.
Drive belts, set
Drive belts, setSet of 4 flexible drive belts made from black synthetic rubber. The belts measure approx. 240 mm, 390 mm, 580 mm and 780 mm. Oil-resistant.
DualScope
DualScopeRobust low-priced hobby/student microscope with simple optical glass objectives mounted on a revolving nosepiece. It comes with a plastic vertical stage with stage clips and a 6-hole disc condenser.
The eyetube is mounted at a 45 degree angle for comfortable viewing and has a wide-field eyepiece with built-in pointer. In addition to the traditional bottom light the microscope is provided with a top light, and is thus also suited for observation of surfaces of leaves, coins, insects etc.
A simple microscope ideal for hobby use and for smaller children. The simplicity of the design makes it a good choice as an introduction to microscopes or as a supplement to the traditional school microscopes.
