Microppose Adherable Injection Port

Self-healing 18 mm injection ports with a 3M adhesive backing. Stick one over a drilled hole in a jar lid or culture container and you can inject through it repeatedly — the port closes behind the needle every time, so the vessel never has to be opened.

That is what makes liquid culture and spore syringe work practical without a flow hood. Every time a sealed vessel is opened, room air and everything in it reaches the media. An injection port removes the open step entirely: the needle goes through, the port reseals, and the media stays isolated from start to finish.

Specifications

• 18 mm diameter
• Self-healing material, rated for repeated needle penetration
• Strong 3M adhesive backing
• Waterproof
• Fully autoclavable, high-temperature resistant
• Applies in seconds, no tools required

Used for: grain jar lids, liquid culture jars, spore syringe inoculation, agar and tissue culture containers, and any vessel that needs repeat access.

Apply ports before sterilizing — they are rated for autoclave temperatures and can go through the cycle in place. Pair with our Microppose adherable lid filters so the same lid breathes and injects, and verify every load with sterilization indicator strips.

Available in packs of 50, 100, 250 and 1,000.
