Safety
P 2.1S/P 4.1S user manual V6870, version 3.1
What must be taken into account?
All safety instructions in the user manual
The environmental, installation, and connection specifications in the user
manual
National and international regulations pertaining to laboratory work
Original spare parts, tools, and solvents made or recommended by KNAUER
Good Laboratory Practice (GLP)
Accident prevention regulations published by the accident insurance compa-
nies for laboratory work
Filtration of substances under analysis
Use of inline filters
Once they have been used, never re-use capillaries in other areas of the HPLC
system.
Only use a given PEEK fitting for one specific port and never re-use it for
other ports. Always install new PEEK fittings on each separate port.
Follow KNAUER or manufacturer's instructions on caring for the columns
More safety-relevant information is listed below:
flammability: Organic solvents are highly flammable. Since capillaries can
detach from their screw fittings and allow solvent to escape, it is prohibited
to have any open flames near the analytical system.
solvent tray: Risk of electrical shock or short circuit if liquids get into the
device's interior. For this reason, place all bottles in a solvent tray.
solvent lines: Install capillaries and tubing in such a way that liquids cannot
get into the interior in case of a leak.
leaks: Regularly check if any system components are leaking.
power cable: Defective power cables are not to be used to connect the
device and the power supply system.
self-ignition point: Only use eluents that have a self-ignition point higher
than 150 °C under normal ambient conditions.
power strip: If several devices are connected to one power strip, always con-
sider the maximum power consumption of each device.
power supply: Only connect devices to voltage sources, whose voltage equals
the device's voltage.
toxicity: Organic eluents are toxic above a certain concentration. Ensure that
work areas are always well-ventilated! Wear protective gloves and safety
glasses when working on the device!
Where is use of the device prohibited?
Never use the system in potentially explosive atmospheres without appropriate
protective equipment. For further information, contact the Technical Support of
KNAUER.
