PASCO Diffusion/Osmosis Kit

Purpose: It's an image found in nearly every biology textbook: a U-shaped tube with a permeable membrane separating a hypotonic and hypertonic solution. And yet few methods of studying osmosis take advantage of this simple and elegant design for lab work. Key Features: - The U-shaped design provides familiarity for students and the straight columns keep the volume of gas above the fluid constant Graduated transparent columns allow changes in volume to be seen and quantified Membranes are quick and easy to replace when compromised Airtight joints prevent pressure leaks Free standing unit requires no additional lab equipment to hold it in place Plastic rather than glass columns for durability and student safety What's Included: 1× PASPORT Dual Pressure Sensor (PS-2181) 1× Diffusion Osmosis Apparatus
