Dialysis tube, 25 mm wide, Ø16 mm
Dialysis tube, 25 mm wide, Ø16 mmThe dialysis tubing is a semipermeable membrane tubing intended for osmosis and diffusion experiments. The tubing is supplied as a 5 meter roll and is 25 mm wide in flat form, while it achieves an internal diameter of approximately 16 mm when filled with liquid.
Diamagnetic floating graphite
Diamagnetic floating graphitePyrolytic carbon is the material with the highest diamagnetic susceptibility at room temperature.
Dicot Stem model, small
Dicot Stem model, smallThe model shows the structure of a stem from a dicotyledonous plant. The vascular and spicate parts are marked in clear colours so that students can see the vascular system. The growth zone is shown in yellow-green and the dermis is in dark green, while non-functional wood is shown in light green.
Digital balance, 15 kg / 1 g
Digital balance, 15 kg / 1 gDigital scale in a slim design with a large weighing plate and an easy-to-read, 5-digit LCD display. The scale has a maximum capacity of 15 kg. and weighs with an accuracy of 1 g.
Digital microscope, USB, 5 MP
Digital microscope, USB, 5 MPSmart USB macro magnifier with 5 MP resolution and included stand, which makes it easy for you to examine small details and surfaces on the screen. The macro magnifier has a built-in LED light with 8 diodes and light control, so you can adjust the lighting as needed. With the included stand, you get a slightly larger working distance and lower magnification, while if you use the magnifier directly on a surface, you can easily adjust the magnification and focus with the focus wheel. The magnifier connects to your computer via USB and comes with Windows-compatible software, where you can both view live images and record photos or videos.

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.
