Limitations of Use

This instrument is designed for dispensing liquids,
observing the following physical limits:
– use temperature from +15 °C to +40 °C (from
59 °F to 104 °F) of instrument and reagent
– vapor pressure up to max. 600 mbar. Aspirate
slowly above 300 mbar, in order to prevent the
liquid from boiling.
– kinematic viscosity up to 500 mm
(dynamic viscosity [mPas] =
kinematic viscosity [mm²/s] x density [g/cm³])
– Density: up to 3.8 g/cm

Operating Exclusions

like ETFE, FEP, PFA, PCTFA
and PTFE (e.g., dissolved sodium azide*)
– liquids which are decomposed catalytically
by platinum-iridium (e.g., H
pending on the construction of the instrument.
– organic solvents
– trifluoroacetic acid
– explosive liquids (e.g., carbon disulfide)
– suspensions (e.g., of charcoal) as solid particles
may clog or damage the instrument
* Dissolved sodium azide permitted up to a
concentration of max. 0.1%.

Operating Limitations

Liquids, which form deposits may accelerate wear
on the piston seal, and make the piston difficult
to move or may cause jamming (e.g., crystallizing
solutions or concentrated alkaline solutions). If the
piston becomes difficult to move, the instrument
should be cleaned immediately (see page 41).
The VITLAB Dispenser TA
®
laboratory applications and complies with the
relevant standards, e.g. DIN EN ISO 8655. Compat-
ibility of the instrument for a specific application
(e.g., trace material analysis, food sector etc.) must
be checked by the user. Approvals for specific ap-
plications, e.g. for production and administration
of food, pharmaceuticals and cosmetics are not
available.

Storage Conditions

Store the instrument and accessories only in
cleaned condition in a cool and dry place.
Storage temperature: from -20 °C to +50 °C
(from -4 °F to 122 °F).
