3 vwr.com I Instruction manual VWR® E-Burette

Follow general and safety instructions for hazard prevention. E.g., always wear protective
clothing, protective gear for the eyes and hands.
Carefully observe the specifications provided by reagent manufacturers.
When dispensing inflammable fluids, avoid the built up of static charge. Make sure that
you do not dispense into plastic vessels and do not wipe the instrument/equipment with a
dry cloth.
Use the instrument only for dispensing liquids, with strict regard to the defined limitations of
use and operating constraints.
Observe operating exclusions. When in doubt, contact the manufacturer or supplier.
Always use the instrument in such a way that neither the user nor any other person is in
danger. While dispensing, the discharge tube must always point away from you or any other
person. Only dispense into appropriate vessels and avoid splashes.
Do not press the piston when the discharge tube closure is attached.
Do not remove the discharge tube while the dispensing cylinder is being filled.
Reagents can accumulate in the cap of the discharge tube. Thus, clean it regularly.
Do not carry the mounted instrument by the cylinder sleeve or the valve block. Breakage or
loosening of the cylinder may lead to personal injury.
Use only original accessories and spare parts.
Do not attempt to make any technical alterations. Do not dismantle the instrument any
further than is described in the Operation Manual.
Always check the instrument for visual damage before use.
If there is any sign of a potential malfunction (e.g. piston difficult to move, stuck valve or
leakage), immediately stop dispensing. Consult the 'Troubleshooting' section of this
Operation Manual and contact the manufacturer if needed.
