2.6 Sample Cell Adapters
CAUTION: Do not
place vials that are
hotter than 100 °C
(212 °F) into any of
the sample cell
adapters. ATENCIÓN: No colocar cubetas cuya temperatura sea superior a 100 °C (212 °F)
sobre los soportes de muestra.
VORSICHT: Die Küvettentemperatur darf beim Einsetzen in die Küvettenhalter
nicht mehr als 100°C (212 °F) betragen.
PRUDENCE: Ne placez pas de cuve de plus de 100°C (212°F) dans un des
porte-cuves d'échantillon.
The DR/2400 Portable Spectrophotometer holds a 1 inch (25.4 mm) diameter
round cell or an AccuVac® Ampul without an adapter. The 16-mm cell adapter
(Cat. No. 59457-00) is used with Test ‘N Tube™, Chemical Oxygen Demand,
Total Organic Carbon, and UniCell procedures. Immunoassay tests and other
procedures using the 1-cm square cell require the square cell adapter
(Cat. No. 59459-00). See
Figure 9 . Tests requiring the multi-pathlength cell
(Cat. No. 59405-00) or Pour-Thru Cell Kit (Cat. No. 59404-00) require the use of
the multi-pathlength cell adapter (Cat. No. 59466-00).
2.6.1 Installing Sample Cell Adapters
To place a cell adapter into the instrument, align the tabs on the adapter with the
alignment recesses in the round-cell holder. Turn the adapter clockwise until the
alignment marks on the adapter line up to the base alignment marks on the
instrument. The adapter will snap into place. Place the sample cell into the cell
adapter. For best results, use only the sample cells recommended in the Hach
procedures.
Remove an adapter by turning it counter-clockwise until the tabs are aligned
with the grooves and the adapter slides out easily.
