2 Safety Instructions
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. 68).
•
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
2.5.1 seripettor®
Never use seripettor® for:
•
Liquids attacking PP, PE or EPDM
•
Hydrofluoric acid and liquids that can release hydrofluoric acid
•
Liquids that tend to polymerize spontaneously (e.g., adhesives and their components)
•
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
•
Hydrofluoric acid and liquids that can release hydrofluoric acid
•
Liquids which are decomposed catalytically by platinum-iridium (e.g., H
•
Liquids that tend to polymerize spontaneously (e.g., adhesives and their components)
•
Suspensions (e.g., activated carbon) because solid particles may clog or damage the instrument
•
Non-polar solvents such as hydrocarbons and halogen hydrocarbons
•
Concentrated or oxidizing acids (except for HCl)
•
Explosive liquids
•
Carbon disulfide
* Dissolved sodium azide permitted up to a concentration of max. 0.1%.
2.6 Storage Conditions
Store the unit and accessories in a cool and dry place in cleaned condition only.
Storage temperature from −20 to 50°C (−4 to 122°F).
