Self-adhesive Injection Ports - 18mm

These self-healing silicone injection ports adhere directly to jar lids and tissue culture containers, letting you inject liquid culture, spores or nutrients while protecting your media from contaminant spores and bacteria. The soft 30-35 Shore C silicone membrane closes around the needle and reseals after withdrawal, and a strong 3M adhesive backing on a transparent base film makes application fast and tool-free. Waterproof and fully autoclavable. Supplied 50 ports per sheet.
