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 w
ater to prevent the polymer from drying in the capillaries. Check
periodically and add distilled water as needed.
Maintain the pump
IMPORTANT! W
ear appropriate protection, including gloves, laboratory goggles, and
coat whenever you work with the uids used on this instrument, or parts that may
come into contact with these uids.
IMPORTANT! T
o minimize background uorescence, 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.
