Safety and Responsibility
25 February 2019 Page 9of 146
2 Safety and Responsibility
This section describes general considerations relating to user
safety that must be taken into account when working with the
equipment.
In the remaining sections, warning notices are used only to high-
light particular hazards directly arising from the actions being de-
scribed in the section in question.
It is essential to read the operating manual carefully – espe-
cially this section and the warning notices in the text – and to
follow the instructions therein.
This section also refers to areas that are the responsibility of the
provider due to certain risks arising from particular applications for
which the equipment is used deliberately and with full awareness
of the associated risks.
2.1 Intended Use, Incorrect Use and Misuse
Depending on its features, the equipment is designed to be
used as an incubation shaker for cultivating microorganisms
or cell cultures only under the following conditions:
Cultivation of non-pathogenic microorganisms or cell
cultures of risk category 1 in a biotechnology labora-
tory of biological protection level 1.
Cultivation of pathogenic microorganisms or cell cul-
tures of risk category 2 in a biotechnology laboratory
of biological protection level 2.
When using the equipment in protection level 2, users are re-
sponsible for taking appropriate protective measures to en-
sure that organisms cannot escape uncontrollably due to
flask breakage, unintentional detaching of the sterile seal or
similar.
WARNING
The equipment is designed and constructed exclusively for the
intended use described above.
Each instance of non-conventional use is considered as misuse
and may lead to dangerous situations.

Multitron - Incubation Shaker
Safety and Responsibility
Page 10 of 146 25 February 2019
Intended use also includes following all the instructions in this man-
ual, especially those relating to:
The installation site
Use of suitable cultivation vessels
User qualifications
Permissible parameter setpoints
Correct operation and maintenance
Any failure to observe the requirements specified in this manual
shall be deemed incorrect use, in particular, use of inappropriate
cultivation vessels and/or unsuitable holders at speeds that are too
high.
Any use of the equipment outside the scope of the intended use as
described above shall be deemed misuse. This also applies to ap-
plications for which the equipment is not designed, especially the
following:
The equipment is not protected against explosions. Use and
manufacture of explosive gases as well as operating the
equipment in the Ex area are therefore not permitted.
The equipment is not designed to sufficiently protect its users
if pathogenic organisms escape uncontrollably. Cultivation of
pathogenic organisms of risk categories 3 and 4 is therefore
not permitted.
To use the equipment for special applications not covered by con-
ventional, intended use, the equipment must be modified and certi-
fied accordingly by the manufacturer.
Any use of the equipment outside of a biotechnology laboratory,
i.e. in any environment in which the conditions required for the
safety of users cannot be met or cannot be met to their full extent,
shall also be deemed misuse.
2.2 Cultivation Vessels to Be Used
Significant forces are applied to cultivation vessels, in particular in
case of large vessels and high speeds. Hence, the cultivation ves-
sels used are particularly significant in relation to user safety.
ATTENTION
Use of unsuitable or defective cultivation vessels can lead to
glass breakage and therefore damage to property.

Multitron - Incubation Shaker
Safety and Responsibility
25 February 2019 Page 11 of 146
Approved cultivation vessels
The equipment has been designed for use with the following ves-
sels using the holders designed specifically for them:
Erlenmeyer flasks up to 5,000 mL made of borosilicate glass
(e.g. Schott Duran®) or high-grade plastic, such as polycar-
bonate (z. B. Corning®) etc.
Fernbach flasks up to 3,000 mL made of borosilicate glass
(e.g. Schott Duran®) or high-grade plastic, such as polycar-
bonate (z. B. Corning®) etc.
Other vessels with the holders designed for them:
Test tubes
Centrifuge tubes
Microtitre plates
Deep well plates
To avoid the vessels coming out of the clamps at very high speeds,
they might have to be secured using cable ties underneath the
springs or some other suitable measure.
Cultivating organisms of risk category 2
When cultivating pathogenic organisms of risk category 2, special
measures must be taken to stop the organisms from escaping. The
user is responsible for this.
When using the equipment under protection category 2, stainless
steel clamps of the correct size must be used to affix the flasks.
Due to limited resistance to disinfectants as well as the risk of unin-
tentional detaching of flasks, «Sticky Stuff» adhesive matting is not
suitable for this purpose.
We further recommend using disposable plastic flasks with screw
tops and filter membranes. We recommend using sticky tape to
secure the lid against loosening unintentionally. Using glass flasks
with cotton wool or paper plugs is not sufficiently safe.
Trays with «Sticky Stuff» adhesive matting
INFORMATION
For trays with «Sticky Stuff» adhesive matting, special provi-
sions apply in relation to maximum permitted speeds. These
must be observed to prevent cultivation vessels from detaching.
For detailed information see chapter 5.1.3 "Tray with «Sticky
Stuff» Adhesive Matting", page 55.

ing from its operation, the equipment may only be used by quali-
fied, specialist personnel.
2.3.1 Provider
The term “provider” applies to all persons who are responsible for
making the equipment and the necessary infrastructure available.
These persons may also be included in the group of people known
as “users”, though this is not always the case.
Irrespective of whether a provider is a member of the company’s
board of management or a supervisor, they bear a special level of
responsibility with regard to the processes and the qualification and
safety of the users.
2.3.2 User
General
The term “user” applies to all persons who come into contact with
the equipment in any way and perform work on or with it. This pri-
marily applies to the following activities, which can be performed by

2.7.5 Pathogenic Organisms
The device is not approved for cultivation of pathogenic organisms
of risk categories 3 and 4. In the context of intended use, it is none-
theless possible for pathogenic organisms and viruses to be culti-
vated. Contact with pathogenic organisms bears a significant

2.8 Safety Features
The equipment comes with the following safety features:
Main switch with emergency switching off function
In addition to allowing you to switch the equipment on and off nor-
mally, the main switch also works as an emergency switch. If the
main switch is switched off, all circuits of the equipment are discon-
nected completely from the grid.
Equipment fuses
Two safety fuses (230 V version) or two thermal protection
switches (115 V version) protect the equipment from impermissibly
high power input. The equipment fuses are located right next to the
mains connection on the left-hand side of the casing. For descrip-
tions of which fuses to use for which equipment type, see chapter
12.2 "Specifications of the Basic Unit", page 129.
Overheating shut-down
The heating of the equipment is protected against overheating by a
temperature limiter. This triggers as soon as the temperature on
the heating element exceeds the maximum allowed value and im-
mediately turns off the heating.
Door monitoring
The position of the door is monitored electronically. If the door is
opened, the shaker drive is stopped immediately. As soon as the
door is fully closed again, the shaker drive restarts automatically.
