Four Doty Scientific High Voltage Capacitor Wands

Description

Four Doty Scientific High Voltage Capacitor Wands.
The four probes are labelled as follows:
#1 is used for 2H at 37.6-53.5 MHz
#2 is used for 14N at 22.5-24.7 MHz
#3 is used for 14N at 21.5-23.5 MHz
#4 is used for 14N at 19.9-21.5 MHz
Two or more high power rf capacitors are mounted on the surface of a printed circuit board that has been developed, etched, and plated to receive the capacitors and to engage mating spring contact fingers for electrical contact between the tuned circuit and the capacitors on one or both sides of the strip. An extension handle is attached to the strip to permit external insertion of the capacitor assembly into close proximity to the coil in an NMR probe, thereby permitting efficient multinuclear capability in a high power NMR probe.
See Patent # 4,710,719 for more info.
No wear can be seen on any of the wands.
