Objective Wrench & Pliers Instructions
Objective Wrench is a tool used to hold the base of an objective while
its outer decorative collar is removed with the Objective Pliers.
Some microscope objectives have an outer sleeve or collar
containing written information such as magnification, N. A., etc.
This sleeve must be removed in order to expose sufficient
cylindrical surface to install the Bioptechs Objective Heater. The Objective Wrench is designed to enable the user to
isolate the stress necessary to be applied to the objective when
removing this collar. The
rotational force applied to the objective must be applied exclusively to
the mounting threads and the collar.
The wrench has with two thread sizes 0.8" x 36 TPI (RMS) and
25mm x 0.75mm/thread. It
will enable the user to securely bind these threads and provide
sufficient leverage for removal of the cover.
