Insulated Neck Plug

Minimize evaporation rates and seal in extreme cold with our high-efficiency Insulated Neck Plug. The neck opening is the most vulnerable area of a liquid nitrogen tank where temperature loss occurs. This core accessory fits snugly into the container opening, acting as a critical thermal barrier that stops valuable gas from venting too quickly, ensuring your stored breeding samples remain safe and frozen for longer periods.

Key Features

High-Density Thermal Foam: Made from specialized, low-conductivity insulating foam that effectively blocks heat transfer and traps extreme cold inside the tank.

Precise Snug Fit: Molded to the exact factory dimensions of the container neck to prevent vapor leaks while remaining incredibly easy to insert and remove.

Integrated Handle Cap: Features a durable, wide top cap that serves as a comfortable handgrip, allowing smooth, hassle-free removal during daily inventory checks.

Built-In Canister Slots: Designed with precise perimeter grooves or notches that allow canister hanger hooks to rest neatly without breaking the tight thermal seal.
