Safety Precautions
• READ the instructions before using the apparatus.
• The exclamation mark within an equilateral triangle
is intended to alert the user to the presence of
important operating and maintenance instructions in
the literature accompanying the instrument.
• Always unplug electrophoresis units from their
power supply before removing the safety cover.
Unplug the power supply from the mains FIRST,
then disconnect the leads.
• DO NOT exceed the maximum operating voltage
or current.
• DO NOT operate the electrophoresis units in
metal trays.
• It is advisable to always place the unit on a plastic
safety tray during electrophoresis.
• Ethidium bromide is a known mutagen. Wear
effective protective clothing when handling and
follow recommended handling and disposal
procedures.
• Ultraviolet light can cause permanent damage to
the retina and skin cancer. Wear UV safety goggles
and cover any exposed skin when using a UV
light source.
• Following the replacement of a platinum electrode,
have the unit inspected and approved by your safety
officer prior to use.
• DO NOT fill the unit with running buffer above the
maximum fill lines.
• DO NOT move the unit when it is running.
•
CAUTION: During electrophoresis, very low
quantities of various gases are produced at the
electrodes. The type of gas produced depends on
the composition of the buffer employed. To disperse
these gases make sure that the apparatus is run in
a well ventilated area.
