Autoclavable Leak-proof Wide-Mouth Mason Jar Lids 86mm – Heavy-Duty Polypropylene for Plant Tissue Culture/Mycology/Canning

Description

Commercial-Grade Autoclavable Mason Jar Lids
Upgrade your spawn and culture jars with reusable, non-corrosive wide-mouth lids engineered specifically for high-heat laboratory conditions. Standard metal lids rust, warp, and degrade after a few pressure cooker cycles—our heavy-duty PP5 (Polypropylene) Autoclavable Lids are built to withstand repeated heat-sterilisation runs without warping or breaking down.

Designed to fit all standard Wide-Mouth Mason / Ball / Fowler Vacola / Kerr jars, these lids provide a clean, rust-free canvas to build custom liquid culture or grain spawn lids using self-healing injection ports and PTFE filter discs.

Key Highlights:

• Autoclave & Pressure Cooker Safe: Made from premium PP5 food-grade polypropylene rated to withstand temperatures up to 121°C (250°F) at 15 PSI.
• Rust-Free & Long-Lasting: Eliminates metal lid corrosion and peeling linings, providing dozens of reuse cycles.
• Universal Fit: Standard 86mm wide-mouth threading compatible with all major wide-mouth glass mason jars.
• Airtight Silicone Seal: Includes a food-grade, heat-resistant silicone sealing ring to prevent moisture loss and contamination during incubation.
• Easy to Modify: Smooth, flat surface ideal for drilling custom ports for filter patches, injection ports, or liquid culture lids.
• Leakproof
• BPA-FREE

Ideal Applications:

• Grain Spawn Jars: Drill air-exchange ports fitted with synthetic filter discs (0.2-micron) for breathing grain cultures.
• Liquid Culture Jars: Modify with self-healing silicone injection ports and gas exchange filters for clean liquid transfers.
• Agar & Slant Storage: Seal tight for clean, sterile long-term culture storage in glass jars.
• Plant Tissue Culture
• Pressure Canning
