Pyrex® MAS Rotor Inserts

Wilmad’s Pyrex® MAS Rotor Inserts are designed for air-sensitive samples and semi solid samples such as gels or highly viscous liquids. The sample can be sealed into the insert tube by heat-sealing with a torch or applying a small drop of epoxy (we recommend E-6000® Craft Adhesive) to the constricted part as shown in the picture below. After the epoxy is set and dry (24 hours), the sealed insert is then cut through the constriction with a glass saw.

Using a small funnel powder samples can be packed into the MAS Rotor Insert. Gelatinous samples can be warmed and transferred to the insert using a syringe. A glove box may be required for the sealing of air-sensitive samples.

These borosilicate glass inserts are specifically engineered for use in MAS (Magic Angle Spinning) NMR rotors.
