Our Gas-Permeable Plates Sealers protect samples in 96-well and 384-well plates while allowing oxygen to flow into the wells.  This facilitates the growth of bacteria, yeast, and other cells in the wells of the microplate.  In order to achieve high cell growth, organisms must be supplied with sufficient oxygen.  By using Gas-Permeable Plate Sealers, rather than a traditional plate lid which can limit oxygen flow, you will significantly improve cell growth.
