Review: work well, flexible rubber - These injection ports work well and are made of a soft, flexible rubber. I use large needles for my mycology cultures, and the ports last between 30-40 injections with a 16ga needle. Once I went past 40 injections, the rubber had trouble self-healing. The way the bottom is designed, the thick walls help for a strong seal with the vial, but they reduce the area that is thin enough to easily stick a needle through to 5mm so the injections are more concentrated to the center of the stopper and not spread across the total surface area. The injection ports last longer with 25ga needles, and you can get 300-400 injections before the stopper starts to have trouble sealing. Review: Work perfect - Been useing them awhile now, very strong rubber. Have literaly been through 100s of Pressure Cooks at 15psi for 90minutes a go. Quality product. ## Features - Material:made of high quality Butyl rubber material, durable, washable and reusable - Size:used for 20mm glass vial and liquid culture jars, fit about 13mm diameter opening - Easy to use: no need to remove the glue plug, you can inject the culture with the injection needle - Perfect seal: resistant to high temperature and washable, creating a great seal that extends the life of the material in the bottle - Various Usages:suitable for kitchen, laboratory, hospital, etc.Great for liquid culture, injection ,refill tanks and grain masterbatches ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.6 out of 5 stars 443 Reviews | ## Images ![100Pcs 20mm Self Healing Injection Ports,vials Rubber stoppers,Butyl Cap for Glass Bottle& Mushroom Liquid Culture Mason Jars by Biomed Scientific(Grey） - Image 1](https://m.media-amazon.com/images/I/61bv5PoDcEL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ work well, flexible rubber *by E***. on November 5, 2024* These injection ports work well and are made of a soft, flexible rubber.
