Operating Instructions - Hoefer MacroVue UV-25 User Manual

Note: To protect the filter from
cuts and corrosive buffers, cover it
with a protective surface such as
the Hoefer UV transmitting work
surface before placing the sample.
Note: To remove the safety cover
for photography, lift the lid into
the up position and pull out both
inserts in the hinge assembly. Take
extra precautions to prevent skin
and eye exposure if the protective
cover is removed.

Operating instructions
1
Place the unit on a stable and level surface. Allow
space around the unit for air to circulate freely.
2
Plug the power cord into the receptacle at the back of
the unit and into a properly-grounded electrical outlet
of the proper voltage rating. (The voltage rating of the
unit is indicated on the label above the power cord
receptacle.)
3
Wear goggles, a UV-blocking face shield, gloves and
cover all exposed skin.
4
Place the sample on the filter and lower the
UV-blocking clear protective cover.
5
Set the variable intensity dial to the highest setting
and switch the power to on. After a momentary
flickering, the UV lamps should light and be visible
beneath the protective cover.
The high-intensity setting is for analytical
documentation and lower settings are for preparative
work (lower settings reduce photonicking and
photobleaching).
6
To reduce the UV intensity, turn the variable intensity
dial to a lower setting. The drop in intensity will
diminish the level of sample fluorescence.
7
After viewing the sample, turn the unit off and
clean according to the instructions in the Care and
maintenance section on the following page.
