Solid-state NMR spectroscopy often requires loading rotors with isotopically labeled gases under vacuum. Traditional glass gas-loading systems are fragile, costly, and bulky typically handmade by skilled glassblowers who are increasingly unavailable at many institutions. These systems are not scalable, portable, or gas-efficient, especially when using expensive labeled gases.
The MAST Gas Loader Cell solves all these issues. This compact, 3D-printed device uses a threaded plunger system with molded silicone grips to hold the rotor cap and insert it under vacuum sealing in the gas without air exposure. The transparent body provides full visibility during operation, and its modular design supports different rotor sizes while keeping internal volume low to reduce gas waste. It’s easy to fabricate, easy to use, and ideal for labs needing flexible, cost-effective gas-loading tools for solid-state NMR rotors.
This cross-sectional rendering shows the internal structure of the MAST Gas Loader Cell. The threaded plunger (green) compresses the rotor cap into position while O-rings (red) ensure a vacuum-tight seal. The design minimizes gas loss and supports precise loading for solid-state NMR rotors of multiple sizes.
