Wilmad Q BAND CFQ EPR TUBES 1.6X1.1X100 OPEN ENDS 10/PK

Q Band Standard EPR Tubes

EPR Tube Q-band is the most popular frequency for pulsed and cw-EPR after X-band.

The larger Zeeman splitting would benefit EPR studies by

(1) improving SNR

(2) requiring less sample

(3) resolving individual components of the g-matrix

(4) disentangling spectra which overlap at X-band

(5) changing the spectral contribution interaction to field-independent interactions

Wilmad-LabGlass offers high quality EPR consumables to cover these high frequency applications.
