Pyrex MAS Rotor Inserts - Product Group B

For air-sensitive samples and semi-solid samples such as gels or highly viscous liquids, the sample is simply sealed into the insert tube by heat-sealing with a torch, or by applying a small drop of epoxy to the constriction. After the epoxy is set and dry, the sealed insert is then cut through the constriction with a glass saw.

Using a small funnel, powder samples can be packed into the insert. Gelatinous samples can be incorporated for the sealing of air-sensitive samples.
