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.
DNA Model 50cm
DNA Model 50cmAssembled
As FR-527565, but with 12 base pairs:thymine (t), 6 adenine (A), 6 guanine (G) & 6 cytosine (C).
The side chains consist of dextroribose (red) and phosphate (purple), which can also be separated.

DNA model, 22 layers
DNA model, 22 layersThis DNA model makes it easier to study the double helix structure.
The model contains 22 base pairs consisting of:
12 thymine (T) (orange), 11 adenine (A) (blue), 11 guanine (G) (green),11 cytosine (C) (yellow).
DNA model, large, for hanging
DNA model, large, for hangingLarge, attractive DNA model, which can be mounted on a tripod pole or hung from the ceiling.
Shows DNA in double helix with 12 base pairs with correct bond angles
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.
