No contamination so clearly doing the job required. ### ⭐⭐⭐⭐⭐ Bonne présentation du produit satisfait *by J***E on 21 February 2026* Très bonne qualité ### ⭐⭐⭐⭐⭐ Bonne résistance à la chaleur *by W***E on 10 January 2025* Conforme à la description. Pour l'injection de mon mycelium à ma culture de champignons j'avais besoin d'un port comme celui ci. J'ai fait un teste en autoclave voir si il tenais bien sur des bocaux de stérilisation et il résiste à une température de 130 degrés plongé dans l'autoclave pendan50 minutes. Il ne ce déforme pas et garde toujours sa texture souple à la sortie d'une température élevé. 10/10 :-) ## Frequently Bought Together - 100Pcs 20mm Self Healing Injection Ports,vials Rubber stoppers,Butyl Cap for Glass Bottle& Mushroom Liquid Culture Mason Jars by Biomed Scientific(Grey） - AOZITA Wide Mouth Mason Jar Lids [16 Pack] for Ball, Kerr and More - White Plastic Storage Caps for Mason/Canning Jars - Leak-Proof - Dishwasher Safe & Food Grade - Zonon 128 Pieces Synthetic Filter Paper Stickers 20 mm 0.3 ?m Synthetic Filter Disc Tape Mushroom Applied Under Wide Mouth Mason Jar for Mushroom Cultivation --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/235298642-100pcs-20mm-self-healing-injection-ports-vials-rubber-stoppers-butyl](https://www.desertcart.hr/products/235298642-100pcs-20mm-self-healing-injection-ports-vials-rubber-stoppers-butyl) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-11*
