2 Basic Safety Instructions
2.1 General information
WARNING !
Warning notices must be observed. Disregarding them may lead to damage to health
and property.
The biovac 106 Aspiration Systems must be operated by personnel who can detect im-
pending dangers and take action to prevent them from materialising.
The manufacturer or authorized workshops will only service or maintain the aspiration sys-
tems if it is accompanied by a fully completed damage report. Precise information about the
contamination (also negative information if necessary) and thorough cleaning of the system
are legally binding parts of the contract.
Contaminated aspiration systems and their individual parts must be disposed of in accor-
dance with the legal regulations.
The local regulations apply in foreign countries.
2.2 Electricity
The biovac 106 Aspiration Systems are supplied for operating mode S1. Please note that
the testing must be repeated in accordance with DIN EN 0105, DIN EN 0702 and BGV A2 in
case of portable devices.
The local regulations apply in foreign countries.
Please note the following when connecting to the electrical power supply system:
The electrical power supply system must have a protective connector according to DIN
VDE 0100-410 (IEC 60364-4-41).
The protective connector must not have any breaks.
The connecting cable must not be damaged.
2.3 Mechanical System
Improper use can lead to injuries or material damage. Observe the following instructions:
Only operate the biovac aspiration systems with hoses of the specified dimensions.
Solid particles in the pumping medium impair the pumping action and can lead to dam-
age. Prevent their penetrating into the pump.
Hazardous substances must be separated out as far as this is technically possible before
they reach the pump.
External mechanical stresses and vibrations must not be transmitted to the system. Only
use a flexible laboratory hose for connecting the aspiration system.
The overpressure generated at the pressure port must not exceed 1 bar.
The pump must not be used to pump liquids.
Set the biovac aspiration systems on a flat and horizontal surface.
Do not close the space beyond the bottom of the device in order to enable the pump to
cool.

Basic Safety Instructions
112037 7
2.4 Hazardous Substances
The responsibility for using the biovac aspiration systems rests with the operator.
Hazardous substances in the gases to be pumped can cause personal injuries and property
damage. Pay attention to the warning notices for handling hazardous substances.
The local regulations apply in foreign countries.
Explosive gases
The aspiration system is not certified according to ATEX guidelines 2014/34/EU.
The system operator is obliged to comply with the ATEX 137 guidelines 1999/92/EC when
us-ing the pump within and for danger areas.
Aggressive gases
An MP series diaphragm pump is used for extracting vapours and aggressive gases.
The warranty shall lapse if the biovac aspiration systems are used with diaphragm pumps
from other manufacturers.
Poisonous gases
Use a suitable separator when pumping poisonous or harmful gases. Prevent such sub-
stances from leaking out of the appliance or pump. Treat these substances according to the
applicable environmental protection regulations.
The diaphragm pump, control valves and hose lines can be damaged by poisonous or ag-
gressive gases.
Test the strength and leak-tightness of the connecting lines and the connected apparatus.
Prevent environmental poisons, e.g. mercury, getting into the diaphragm pumps.
Fulfil the requirements, for example:
German Hazardous Substances Regulation (GefStoffV) of 01. December 2010
Regulations 2016/1179/EU
(classification, packaging and identification of hazardous substances),
Manufacturer's safety data sheets on hazardous substances.
2.5 High Temperatures
The diaphragm pump may heat up as a result of the temperature of the gas being pumped
and through compression heat.
Prevent the following maximum permissible temperatures from being exceeded.
+ 40 °C for the environment and
+ 40 °C for the medium to be pumped.
The motor for single phase alternating current is protected against overload by a fine-wire
fuse and integrated motor-protective switch.

3 Description
3.1 Design
►Aspiration System biovac 106 with secretion glass container 2 liters
A filter holder for a PTFE filter is located between the secretion glass container (1) and the
diaphragm pump (2). Filters down to a minimum pore size of 0.22 µm may be inserted in this
holder. According to the filter fineness used, it is possible to achieve different types of filtra-
tion, enabling, among other uses, the handling of bacteria and viruses.
The cap (3) of the secretion glass container consists of a plastic cap with a seal.
Fig. 1a Aspiration-System biovac 106 with secretion glass container 2 liters
A quick coupling (4) is used for the connection to the diaphragm pump (2). It is provided with
a stop valve.
The used-resistant diaphragm pump (2) used has a long useful life.
Secretion container (1) and handvac (5) are connected with a hose (6). After disconnecting
the unions (7), the two flexible tube ends at the container may be connected to one another
to ensure safe transport.
The Aspiration System is switched on and off directly at the device switch or the optionally
available foot switch (9).
The user appropriate pipette tips (8) can be used in the respective adapter of the handvac
(5). All hoses (6) located outside of the Aspiration System are made of silicone.

►Aspiration System biovac 106 with secretion PP - container 4 liters
Between secretion - PP container (1) and membrane pump (2) is a inline filter (10) with a
pore size of 0.22 microns to protect the membrane pump against pollution caused by fine
solid particles and aerosols.
Fig. 1b Aspiration-System biovac 106 with secretion PP - container 4 liters
3.2 Function
The biovac Aspiration Systems with an integrated resistant diaphragm pump is used for the
safe and precise aspiration of non-flammable chemical and biological liquids.
The fluids can be removed easily and very precisely from slides, Petri dishes, cell culture
containers etc., by using different pipets or glass tips which are inserted into the handvac.
The integrated secretion container has a built-in float valve. This valve shuts the suction line
automatically as soon as the maximum fill level is reached.
A hydrophobic PTFE filter with a suitable filtration grade is inserted in order to provide
additional safety. The scope of supply includes a filter with a filtration grade of 1 µm.

5.3 Operation
CAUTION!
Observe the basic safety instructions when using the aspiration systems!
CAUTION!
Before the device is switched on, the voltage selector must be set with a screwdriver
to the voltage of the local power supply, either 115 or 220 V (+/-10%).

Installation and Operation
112037 15
Procedure:
1. The biovac aspiration systems is switched on and off at the operating switch (illuminated
rocker switch).
2. Set mode selector switch to "Hand".
3. For operation using the optional foot switch, set the selector switch to the "Foot" position
and actuate that switch.
4. A low air pressure is generated in the reservoir.
5. Press the black button at the top side of the “handvac” to suck the fluid into the reservoir.
6. A regulator screw is located at the bottom side of the “handvac”. It is used to set the ex-
traction speed.
7. For the safety of the user, a 55 mm PTFE filter (if necessary hydrophobic) suitable for
the requirements and work task must be inserted into the filter casing.
CAUTION !
Please observe the operating instructions included when using the "handvac" !
5.4 Storage
The pumps are to be stored in a low-dust, interior room within the temperature range from
+ 5 to + 40 °C and at a relative air humidity < 90%.
Leave the protective elements on the intake and pressure ports. Another equally good pro-
tection may be used.
5.5 Scrap Disposal
CAUTION !
The aspiration systems must be disposed of in accordance with the 2012/19/EU
guideline and the specific national regulations.
Contaminated systems must be decontaminated according to the laws.
The user is responsible for disposing of the products extracted and decontaminating the se-
cretion container and hoses.
Secretion glass container and container cover are autoclavable. Against hoses and pipettes
are expendable materials.
A contaminating of the diaphragm pump is to be avoided by use of a suitable filter.
The used materials of the gas-affecting parts are glass, PP, PEEK, PTFE and EPDM.
