Functions And Limitations Of Use - BRAND seripettor FEP Operating Manual

The bottle-top dispenser seripettor
and is offered in two models: seripettor
When the instrument is correctly used, the dispensed liquid comes into contact with only the following
chemically resistant materials:
seripettor : FEP, PP, PE, EPDM
®
seripettor pro : PP, PE, Borosilicate glass, AI
®
seripettor
®
Limitations of Use
This instrument is designed for dispensing liquids,
observing the following physical limits:
– use between +15 °C and +40 °C (59 °F and
104 °F) of instrument and reagent
(seripettor : agar culture media up to 60 °C)
®
– vapor pressure up to 500 mbar
– kinematic viscosity:
2 ml instrument: 300 mm
10 ml instrument: 150 mm
25 ml instrument: 75 mm
(dynamic viscosity [mPas] =
kinematic viscosity [mm²/s] x density [g/cm³])
– density up to 2.2 g/cm

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).
When dispensing inflammable media, make sure
to avoid to buildup of static charge, e.g., do not
dispense into plastic vessels; do not wipe instru-
ments with a dry cloth.
The seripettor 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 produc-
tion and administration of food, pharmaceuticals
and cosmetics are not available.
