4. Operating Exclusions
When the instrument is correctly used, the dispensed liquid comes
into contact with only the following materials:
Borosilicate glass 3.3, FEP, ETFE, PFA, PTFE and platinum-iridium.
Never use this instrument for:
– Liquids which attack FEP, ETFE, PFA and PTFE
– Solutions containing hydrofluoric acid
– Solutions which tend to crystallize, fuming acids and concen-
trated bases
– Suspensions containing solid particles
– Solutions which decompose and form solid particles (e. g.,
Biuret reagent)
– Substances which undergo catalytic transformation or react
with platinum-iridium (e. g., H
2
O
2
)
– Carbon disulfide as this media inflames easily
– The instrument should not be used in an aggressive atmos-
phere (e.g., HCl fumes).
– The instrument must not be autoclaved!
