Some EPR samples are air-sensitive. Since oxygen is paramagnetic, many EPR samples are best studied after degassing. For long-term storage, no other closure is better, but most vacuum racks incorporate Pyrex® components. Sealing quartz to Pyrex® is a problem, unless you use sample tubes that incorporate a graded seal. Order Wilmad's Graded Seal/Constricted EPR Tubes, available in a variety of sizes.
