2. Application and Operating Limitations
This instrument is designed for dispensing of aqueous and highly diluted
agents, observing the following physical limits:
– use temperature from +15 °C to +40 °C of instrument and reagent
– density up to 2.2 g/cm
– vapor pressure up to 500 mbar
– viscosity up to 200 mm
3. Operating Exclusions
The user has to ensure the compatibility of the instrument with the
intended application.
When the instrument is correctly used, the dispensed liquid comes into
contact with only the following materials:
Borosilicate glass, FEP, ETFE, PFA, PTFE and Platinum-Iridium.
Never use Dispenser with:
– Concentrated acids and alkalis
– Liquids which attack FEP, ETFE, PFA and PTF; e.g., dissolved sodium
azide
– Liquids attacking borosilicate glass (e.g., hydrofluoric acid
– Suspensions (e.g., of charcoal) as solid particles may clog or
damage the instrument
– Solutions which decompose and form solid particles
(e.g., Biuret reagent);
– Substances which undergo catalytic transformation or react with
Platinum-Iridium (e.g., H
– Explosive liquids (e.g., carbon disulfide)
– Tetrahydrofuran
– Trifluoroacetic acid
