Silicone Sponge Closures, 28 mm (CAT#: STEM-L-2316-LC)

The Silicone Sponge Closures are ideal for aerobic culture. They allow for efficient gas exchange. Compared with cotton plugs, they can also reduce the loss caused by evaporation by half, thereby minimizing changes in pH. They can be repeatedly sterilized by dry heat at a temperature of 180°C, and are easy to clean and maintain (reusable).

Size: 28 mm
