Osmose meter

Osmose meter for educational use
For experiments by biology.
Place an dialyse membrane in this item (diameter circa 33 mm)
I used lemonade as high concentrated sugar liquid in the meter and tap water outside the meter
Works fine with high concentrations (lemonade =~ >50% Sugar)
But sadly not when compare 5% Sucrose with 5% Glucose
Easy use. No leakage, exact fit O-ring used.
