WARNING!
SHARP The load-end of the capillary array has small, blunt ends
that can lead to piercing injury.
If you remove a capillary array for storage, insert the loading-end of the capillary
array in distilled water to prevent the polymer from drying in the capillaries. Check
periodically and add distilled water as needed.
Maintain the pump
IMPORTANT!
Wear appropriate protection, including gloves, laboratory goggles, and
coat whenever you work with the fluids used on this instrument, or parts that may
come into contact with these fluids.
IMPORTANT!
To minimize background fluorescence, use clean, powder-free,
silicone-free latex gloves whenever you handle the pump assembly or any item in the
polymer path.
The polymer delivery pump can be irreversibly damaged if:
• Polymer dries in the polymer channels of the pump assembly, which can scratch
the channels in the pump, and can cause blockage.
• The pump assembly is exposed to organic solvent, which can cause cracking and
clouding of the acrylic pump material.
• The pump assembly is exposed to temperatures greater than 40°C, which can
damage the pump components.
• There is arcing in the pump assembly, which can damage the acrylic pump
material.
