Description

Need to seal an EPR tube to your vacuum rack?
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. Other configurations can be prepared, so if you don't see the size you need.
