Used two of these so far to inoculate a couple bags of grain with some chestnut culture. The bags remained sealed, letting no air in or out. Colonization rate seems good and there are no contaminations. These are definitely worth the price for a beginner mycologist.

These are indeed the best self injection ports. I’ve used others and they tend to need specific sized holes for a perfect seal to keep contamination away from your project. These you only need to make a hole big enough for your needle and then stick one of these puppies on. The healing factor is amazing. Less than a second and could barely tell I ever punctured the port. Not to mention they can handle multiple runs through a pressure cooker. Still have yet one to feel as if it lost its bond to my mason jar lid.

These were great for mushroom green bags after sterilizing them. The glue is very sticky and resealed itself with a 16 gauge and a 14 gauge needle.

Used these on Mason jars for mushroom grain spawn. These stayed on well after putting them through the pressure sterilizer. I am having successful mycelium growth with no contamination in all 12 jars that I made so they seem to work well.

Well, they serve a pretty simple function. They work well and I've had no issues whatsoever.

Perfect size and does an excellent job sticking and forming to the plates. Definitely creates a strong barrier and confident it will keep any contamination out of my agar work. Good stuff!

Work well and adhesive cleanly survives the autoclave.
