Elevate your mushroom cultivation with the Ultimate Injection Ports from DrMyc — the gold standard for serious mycologists and hobbyists alike. These ports are built to outperform the competition in durability, reusability, and contamination resistance. Developed by professional mycologists, DrMyc injection ports are trusted by growers nationwide for their truly self-healing design, preventing contaminants from compromising your grain jars or liquid culture setups. 🧪 Key Benefits: Truly Self-Healing for 50+ Uses: Unlike standard ports that degrade after a few perforations, DrMyc's premium silicone formula with an 8mm thickness reseals tightly after each needle injection — even after 50+ perforations. Extra-Large 10.2 mm Diameter: Wider and more secure than typical repurposed or adhesive ports, our design provides a snug, flush fit and seals stronger — without risk of leaks or pull-outs. Ultimate Contamination Defense: Airtight seal ensures no outside air, mold, or bacteria enter your sterile environment. Great for LC jars and grain spawn jars. Never Pulls Out or Warps: High-grade adhesive and oversized design lock firmly into lids without lifting, warping, or dislodging during sterilization. Designed by Experts, Trusted by Growers: DrMyc products are created by a professional mycologist and battle-tested in real-world grow operations. Whether you're inoculating liquid culture, grain spawn, or agar, DrMyc Ultimate Injection Ports deliver the reliability, longevity, and sterility that mushroom growers demand. Make every injection count — choose the injection port that doesn't quit: Our purpose designed injection ports are the only injection ports custom designed with Mycology in mind. All other injection ports on the market are actually bottle or test tube stoppers, which are not made to be used multiple times, and are usually 1mm or less thick, limiting their "self healing" ability. Our injection ports offer more features, more longevity, less contamination & (not for nothing) look way cooler than the competitions' repurposed bottle stoppers: - Each injection port has 8 mm of injectable area, allowing for multiple injections - Each injection port can be used in excess of 10 times before any damage to the self-healing port underneath is observed we've used our ports for over 50 inoculations before replacing them - While most other "injection ports" contain only 1mm of injectable area leaving your jars susceptible to contamination, DrMyc injection ports are solid rubber the whole way through (8mm depth) - Each injection port has a lip to lock onto the jar lid - meaning no chance your injection port will pop out with your inoculation pull-out - DrMyc is an American owned and operated company, every dollar you spend with us helps a small American business
