Safety Instructions
This instrument may sometimes be used with hazardous materials, operations, and equipment. It is beyond
the scope of this manual to address all of the potential safety risks associated with its use in such applica-
tions. It is the responsibility of the user of this instrument to consult and establish appropriate safety and
health practices and determine the applicability of regulatory limitations prior to use.
1. Every user must read and understand this
operating manual before operation.
2. Follow general instructions for hazard preven-
tion and safety instructions; e.g., wear protec-
tive clothing, eye protection and gloves.
3. Observe all safety precautions provided by
reagent manufacturers.
4. When dispensing flammable media, make pro-
visions to avoid electrostatic charging, e.g., do
not dispense into plastic vessels; do not wipe
instruments with a dry cloth.
5. Use the instrument only for dispensing liquids,
with strict regard to the defined limitations of
use and operating limitations.
Observe operating exclusions (see page 30)! If
in doubt, contact the manufacturer or supplier.
6. Always use the instrument in such a way
that neither the user nor any other person is
endangered. When dispensing, the discharge
tube must always point away from you or any
other person. Avoid splashes. Only dispense
into suitable vessels.
7. Never press down the piston when the dis-
charge tube closure/screw cap is attached.
8. Secure the piston lock during operation.
9. Never remove the discharge tube while the
dispensing cylinder is filled.
10. Reagents can accumulate in the closure cap/
screw cap of the discharge tube. Thus, it
should be cleaned regularly.
11. For small bottles, and when using the flexible

For serial dispensing the optional flexible discharge tube can be used (see 'Accessories' page 46).
The specified accuracy and coefficient of variation of the instrument are only obtained for volumes > 2 ml
and by gently approaching the upper and lower stops. The coil of the tubing can be stretched to a length
of the 800 mm max. The entire coil must lie in regular loops and must not be twisted.
The parts in contact with the media are made of: borosilicate glass, AI2O3ceramic, ETFE, PTFE,
platinum-iridium, PP.
Therefore, never use the flexible discharge tube for:
– liquids attacking borosilicate glass (e.g., hydrofluoric acid)
– Peroxides, as they are decomposed catalytically by platinum-iridium (e.g., H2O2)
Additionally the operating exclusions of the instrument apply.
Warning:
There should be no visible damage to the discharge tube (e.g., kinks
or the like). Each time you are going to use the tubing, examine it
carefully! To dispense aggressive liquids, you should take safety mea-
sures in addition to the normal precautions. We recommend use of a
protective shield. The bottle must be supported using a bottle stand.
To help avoid reagent splashing from the tube, always grip the tube
firmly by the handle and replace into the holder after use. For clean-
ing rinse the tube carefully. Do not dismantle!
Dispensing with flexible discharge tube
a) Attach the tube holder onto the valve
block and mount the receiver tube
(fig. a).
b) seripettor®: prior to mounting the
flexible discharge tube, remove the
installed elastomer sealing ring and
replace it with the accompanying
PTFE-sealing ring.
c) Check whether the gasket is properly
seated in the adapter (fig. c)!
d) Slide the discharge tube onto the
adapter and firmly finger-tighten the
locking nut. Then, slide the adapter
onto the valve block and firmly finger-
tighten the locking nut.
Use a bottle stand (fig. d).

Error Limits
Error limits related to the nominal capacity (= maximum volume)
indicated on the instrument, obtained when instrument and distilled
water are equilibrated at ambient temperature (20 °C/68 °F). Testing
takes place with a completely filled instrument and with uniform and
smooth dispensing.

Checking the Volume (Calibration)
Depending on use, we recommend that gravimetric testing of the instrument be carried out every
3-12 months. This time frame should be adjusted to correspond with individual requirements.
Gravimetric volume testing according to DIN EN ISO 8655-6 (for measurement conditions,
see 'Error Limits', page 38) is performed as follows:
