2.1 General safety instructions

Please read carefully!
The instrument Dispensette® S can be used in combination with hazardous materials, work processes
and equipment. However, the operating manual cannot cover all of the safety issues that may occur in
doing so. It is the user's responsibility to ensure compliance with the safety and health regulations
and to specify the corresponding restrictions before use.
1.
Every user must read and observe this operating manual before using the device.
2.
Follow the general hazard instructions and safety regulations, e.g. wear protective clothing,
eye protection and protective gloves.
3.
Observe all specifications provided by reagent manufacturers.
4.
When dispensing inflammable media, make sure to avoid to buildup of static charge, 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. Comply with the operating exclusions (Operating Exclu-
sions, p. 46)! If in doubt, contact the manufacturer or supplier.
6.
Always perform work in a manner that does not endanger yourself or other people. When dis-
pensing, the discharge tube must always point away from you or any other person. Avoid
splattering. Only use suitable vessels.
7.
Never press down the piston when the discharge tube closure is attached.
8.
Never remove the discharge tube while the dispensing cylinder is filled.
9.
Reagents can accumulate in the screw cap of the discharge tube. Thus, the screw cap should
be cleaned regularly.
10.
For small bottles, and when using the flexible discharge tube, use a bottle stand to prevent tip-
ping over.
11.
Never carry the mounted instrument by the cylinder sleeve or the valve block. Breakage or
loosening of the cylinder can lead to personal injury from chemicals (First Steps, p. 52, Fig. 3).
12.
Never use force. Use smooth gentle movements to operate the piston upwards and down-
wards.
13.
Use only original accessories and original replacement parts. Do not make any technical modi-
fications. Do not dismantle the instrument any further than is described in the operating man-
ual!
14.
Always check that the instrument is in proper working condition before use. The user can
come into contact with media if the instrument has been insufficiently cleaned or inspected. If
there is a sign of a potential malfunction (e.g., piston difficult to move, sticking valves or leak-
age), immediately stop dispensing and consult the Troubleshooting section of this manual
(Troubleshooting, p. 68). Contact the manufacturer, if necessary.
