Digital microscope, USB, 5 MP
Digital microscope, USB, 5 MPA neat little microscope with 5 MP resolution and stand. Easy to use for examining small details and surfaces, and includes adjustable built-in LED illumination. When mounted in the stand, allows a slightly larger working distance, and less magnification. When holding it over a surface, you can use the focusing wheel to ensure sharp images at two different magnifications. Supplied with Windows and Mac compatible software.
Discover Pi Set
Discover Pi SetThis set allows students to derive the meaning of pi directly from their measurements. Includes four plastic disks with varying diameter in each set.

Dr FuelCell fuel cell car, basic
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.
Drop Dispenser
Drop DispenserThis Drop Dispenser has a 60 mL reservoir and two stopcocks to facilitate titrations.
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.
