For glucose determination, 10 x 50 ml.
Separate the lightweight and durable two-piece polypropylene funnels for easy cleaning. These funnels won't chip, crack or break.
Used in various (vacuum) filtration operations.
Cylindrical body to demonstrate the temperature dependence of buoyancy.
If the body is placed in a vessel filled with cold (approx. 10 °C) water, the body will float.
If the body is placed in a vessel filled with hot (ca. 90 °C) water, the body sinks to the bottom.
At a temperature of about 50 °C, the body begins to rise to the surface in the vessel.
Edges: 100 mm
By filling the cuvette - liquid lens with different liquids and pointing the laser(beams) at the "liquid" lens, it is possible to demonstrate the refractive indices of different liquids.
Cuvette dimensions 105x50x20mm.
On the back of the cuvette there are magnets for fixing the cuvette vertically.
The set contains 2 cylindrical bodies and two 100ml measuring cylinders.
If the body is placed in a measuring cylinder filled with cold (approx. 10 °C) water, the body floats.
If the body is placed in a measuring cylinder filled with hot (ca. 90 °C) water, the body sinks to the bottom.
At a temperature of about 50 °C, the body begins to rise to the surface.
Two devices included in set.
A base plate with a motor, to which one of the eight supplied colored disks can be connected. When starting the electric motor, the colors of the discs merge into one. Required external DC supply voltage 2...6V.
