Cleaning

5.1.1 Spectrophotometer

5.1.2 Sample Cells

5.1.3 Pour-Thru Sample Cell

CAUTION
Do not use the
Pour-Thru Cell in
tests that call for
the use of organic
solvents such as
toluene,
chloroform,
trichloroethane or
cyclohexanone.
These solvents may
not be compatible
with the plastic
components of the
Pour-Thru Cell
creating the
potential for
equipment damage
and chemical
exposure for the
analyst.

MAINTENANCE

Keep the spectrophotometer and sample cells clean at all times. Wipe up
spills promptly. Use a lens tissue or a soft, lint-free cloth (that will not
leave an oil film) to wipe the photocell window located on the left-hand
side of the cell holder.
Clean sample cells with detergent, rinse several times with tap water, and
then rinse thoroughly with demineralized water. Some cells may require
acid washing or other special cleaning procedures (see each procedure).
Rinse sample cells used with organic solvents (chloroform, benzene,
toluene, etc.) with acetone before the detergent wash, and again as a final
rinse before drying. Polystyrene disposable sample cells are available
(refer to REPLACEMENT PARTS).
Remove the Pour-Thru cell occasionally to check for accumulation of
film on the windows. If the windows appear dirty or hazy, soak in a
detergent bath and then rinse thoroughly with demineralized water. Do
not use solvents (e.g., acetone) to clean the Pour-Thru cell. The Pour-Thru
cell can be disassembled for cleaning if necessary.
ADVERTENCIA
No utilice la Célula de Flujo Continuo para pruebas que requieran el uso deo solventies
orgánicos tales como tolueno, cloroformo, tircloretano o ciclohexanona. Es posible que
estos solventes sean incompatibles con los componenetes de material plástico de la
Célula de Flujo Continuo y existe el riesgo de daños al equipo y exposición del analista
a las substancias químicas.
AVISO
Não use a Pilha de Vazamento em testes que exigem o uso de dissolventes orgánicos
como tolueno, cloroformo, tricloroetano e ciclohexanona. Existe a possibilidade que
estes dissolventes não dejam compatíveis com os componentes de plástico da Pilha de
Vazamento, o que pode criar a possibilidade de estrago ao equipamento e exposição
química para o analista.
ATTENTION
Ne pas utiliser la cuve à circulation dans les techniques d'analyses qui utilisent des
solvants organiques tels que le toluène, le chloroforme, le trichloroéthane ou la
cyclohexanone. Les solvants organiques peuvent ne pas être compatibles avec les
composants en plastique de la cuve à circulation et endommager l'équipement en créant
un risque chimique pour l'opérateur.
WARNHINWEIS
Die "Pour-Thru-Zelle" darf nicht in Tests verwendet werden, die organische
Lösungsmittel wie Toluol, Chloroform, Trichlorethan oder Cyclohexanon erfordern.
Die Möglichkeit besteht, daß diese Lösungsmittel nicht mit den Kunstoffkomponenten
der "Pour-Thru-Zelle" kompatibel sind und somit Geräteschaden verursachen und
eine Chemikaliengefahr für den Untersuchungschemiker darstellen können.
