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.

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.
