Langmuir trough
WebbLangmuir and Langmuir Blodgett trough tops are made from single pieces of pure PTFE for optimized cleanliness and reliability. This unique design prevents any leakage in any part of the trough top including the dipping well. It avoids the use of potentially contaminating glues or other seals. WebbWhen you compress the monolayer area decreases but the number of surfactant molecules remains the same. Thus the area per molecule is decreased. number of …
