4. Dampen cloth with water. Use it to clean the instrument from the outside, including the
display and the keyboard.
9.2 Cleaning Quartz Cuvettes
It is important to maintain the cleanliness of quartz cuvettes so that residues from prior
analyses do not contribute errors to future measurements. For most biological samples, the
following cleaning procedure will help keep these cuvettes working optimally for your
spectrophotometery system.
1. Wash cuvette with warm water.
2. Clean the cuvette with a mild acidic solution (0.1M HCl).
3. Rinse the cuvette with copious amounts of water.
Be sure not to use abrasive materials to clean the cuvettes as they may scratch the optical
surfaces and shorten the life of the cells. Similarly, care must be taken not to use highly acidic
(HF) or highly basic (>pH 9) to clean the cells as the optical surfaces could be damaged.
9.3 Changing Thermal Printer Paper
Installing New Thermal Printer Paper
Note: Use only Bio-Rad recommended thermal paper catalog number 170-2506.
• Remove printer paper door cover by pushing down on the center of the door and sliding
the door back away from the unit.
• Remove plastic core shaft from old paper roll and insert into center hole in new paper
roll.
• Un-roll enough paper to allow for enough space to feed leading edge of paper into slot
opening in paper storage area as shown in above figure.
Note: Feed paper from bottom of roll as shown. Do not fold or crease leading edge of
paper.
