- - - - Wash off any excess sucrose solution from the outside of the cellophane membrane and pat dry both tubes with the paper towels, check for the leaks and place the cellophane membrane with stand
        
        Immerse the cellophane membrane in the beaker containing water
        
        Leave it for 60 minutes then record the movement of solution in the pipette cavity rises above the initial every 10 minutes
        
        Similarly, set up the experiment using 2 M sucrose solution
- - - - Remove the assembled apparatus from the water. Hold it so that the tem cutting is upright
        
        Clamp the assembly to a ring stand. The water will not run out of the tube due to water’s adhesive and cohesive properties
        
        Place the assembled apparatus under the lamp. Observe the level of water in burett every 5 minutes for the next 40 minutes
        
        Mark the water level and measure (in ml) the distance the water has moved. Record your data
- - - - Immerse the 2 dialysis tubes in the side arm flasks
        
        Leave it for 1 hour, record the movement of solution every 10 minutes.
- - - - Now pour some water in the glass tube until water level can be seen above the rubber tube
        
        Mark the level of water in tube
        
        Keep your arrangement aside for 1 hour
        
        Observe and mark the water level in the tube
