Dialysis Bag Holder
Strong plastic clip designed to fasten over the rim of a large beaker to easily suspend dialysis tubing bag. Holder may be marked for sequencing. Six per package.
AP4348 I $26.00
Dialysis Tubing and Clamps
Regenerated, seamless cellulose membrane tubing for dialysis demonstrations. Choose from three widths, each in three lengths. One-piece polypropylene, reusable clamp eliminates tying knots in dialysis tubing. Fits tubing with flat width up to 45 mm.
AP4351 I Tubing I $7.25 AP4349 I Clamp I $2.35
Plasma Membrane Model
Bring the fluid mosaic membrane out of textbooks and into the classroom with this model. Students view molecular structure of the phos- pholipid molecules and membrane structure as a whole. Rock the model back and forth to demonstrate the membrane’s fluid nature. Model includes a membrane protein that can be moved with a magnet to represent different membrane proteins and show how the membrane structure is not disrupted by the protein motion.
FB1768 I $57.50
Disposable Dialysis Tubing Clamps
An inexpensive dialysis tubing clamp that works! Just twist the end of the wet dialysis tubing a few times, place the clamp over the twisted area, and squeeze the vise-like clamp together. Package of 100.
FB1232 I $14.55
Diffusion Demonstration Model
Students love this functioning diffusion model. 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!
