Dialysis Funnel/Holder
The dialysis funnel/holder attaches to dialysis tubing with a rubber band and
requires a separate tubing clamp or knot for the other end. The funnel/holder will
accommodate tubing up to 45 mm flat-width and will attach to the rim of any appropriate

Diffusion
Demonstration Model
By: The Flinn Staff
The semipermeable membrane in the center of the model allows the passage of
“small” molecules while keeping the “large” molecules trapped on one side of the
membrane. Randomly shake the model and watch what happens! The dramatic
increase in volume on one side will help students visualize difficult concepts of
diffusion and membrane permeability.

FB1573 Diffusion Demonstration Model $23.45
Plasma Membrane Model
By: The Flinn Staff
Students easily view the molecular structure of the phospholipid molecules, as
well as the structure of the membrane as a whole. Rock the model back and forth
to demonstrate the fluid nature of the membrane. The model includes a membrane
protein. Move the protein around the membrane using a magnet to represent different
types of membrane proteins and to show that the structure of the membrane is
not disrupted by the motion of the protein. Can be reused for years!
A strong magnet is required and sold separately.

Double Thistle Tube, Osmosis Apparatus
Molecules diffuse through the semi-permeable membrane at the bottom of the
double thistle tube. The thin column of the thistle tube magnifies the volume and
color changes.
This easy-to-use set includes a 16" double thistle tube, an aluminum thistle tube
support stand, a battery jar, a semi-permeable membrane and instructions.

Animal Cell Model
12 key structures of an animal cell are illustrated with this large, colorful, crosssectional
model. The protective transparent cover can be removed for easy viewing
of the inside of the cell, while still maintaining the three-dimensional focus of a real
cell. Teaching strategies are included in the Teachers Guide as well as a key to the
numbered structures on the model. The cell is 8" in diameter—stand included.
