13mm Self Healing Injection Ports Vials Rubber Stoppers Mushroom Mason Jar Lids Butyl Seal for Glass Bottle& Liquid Culture Production Jars 100Pcs/Pack by Biomed Scientific(Red) …

Do exactly what I need them to do.

If you're looking for injection ports to make your own mycology lids, these are the ones you want. A 12 mm hole drilled in the lid, and these will press fit right in, no adhesive or silicone necessary. They have worked perfectly for me for my liquid cultures - no contamination. I have also used them on my grain jars by just spritzing down both sides with 70% isopropyl alcohol before putting them on.

Fits on regular mason jars

Works as intended.

I bough these to use on mason jar lids - as an injection point mushroom culture. Package arrived in good shape and no funky / chemical smells from the ports.I've used a dozen of the ports without issue. I'm cheap so I have actually reused a half dozen of the lids - again no problems. Both times pressure cooked for 2 hours at 15 lbs. I'm guessing I will get several more uses out of each before I have to toss the lids and make new ones with new ports.Not much else to say - they seem to work and no issues seen.

These are exactly what you hope them to be and they work fine.

Is correct product

I sterilized Mason Jars with modified lids (PFTE Filter and these self healing injection ports). Injecting spores into the jar left a small hole that leaks the liquid culture broth when the jar is turned upside down. These are definitely not self healing.

Justo lo que necesitaba para un experimento

I've used more than 15 of these since I have had them. No contamination so clearly doing the job required.

These are decent injection ports. The delivery took longer than most items, but I'd rather wait for a good quality item and these are good quality.

Llegaron antes de lo esperado y se ven de buena calidad, la relación con el precio es excelente
