Operating Limitations; Operating Exclusions; Storage Conditions - BRAND seripettor Operating Manual

2.4 Operating Limitations

•
Liquids, which form deposits may make the piston difficult to move or may cause jamming (e.g.,
crystallizing solutions or concentrated alkaline solutions). If the piston movement becomes slug-
gish or stiff, the instrument should be cleaned immediately (Cleaning, p. 55).
•
When dispensing inflammable media, make sure to avoid to buildup of static charge, e.g., do not
dispense into plastic vessels; do not wipe instruments with a dry cloth.
•
The instrument is designed for general laboratory applications. Compatibility of the instrument
for a specific application (e.g., trace material analysis, food sector etc.) must be checked by the
user. Approvals for specific applications, e.g. for production and administration of food, pharma-
ceuticals or cosmetics are not available.

2.5 Operating Exclusions

•
Liquids attacking FEP, PP, PE or EPDM
•
Non-polar solvents such as hydrocarbons and halogen hydrocarbons
•
Concentrated or oxidizing acids
•
Explosive liquids
•
Carbon disulfide
2.5.2 seripettor® pro
Never use seripettor® pro for:
•
Liquids attacking PP, PE, Al
•
Liquids attacking borosilicate glass (e.g., hydrofluoric acid)
•
Liquids which are decomposed catalytically by platinum-iridium (e.g., H
•
Non-polar solvents such as hydrocarbons and halogen hydrocarbons
•
Concentrated or oxidizing acids (except for HCl)
•
Explosive liquids
•
Carbon disulfide
•
Suspensions (e.g., activated carbon solutions) as solid particles may clog or damage the instru-
ment
* Dissolved sodium azide permitted up to a concentration of max. 0.1 %.

2.6 Storage Conditions
