A Round Air Filter Vent 0.22 Micron with 3m Backing is a small circular filter used for facilitating gas exchange in live culture containers, grain jars, and liquid cultures. The filter has a 0.22-micron rating, which means it can effectively trap particles and contaminants, preventing them from entering the culture. The filter also has a 3m backing, which is a strong adhesive that allows the filter to be easily applied to clean hard surfaces, such as standard metal and plastic jar lids. This product is waterproof and reusable, making it a popular choice for DIY projects and scientific applications.
