LABEC Z-L-450 - Manual (Page 5)

1 st . Terms of safety using
User’s better use it in accordance with the design of it; it may result in equipment damage or personal
injury if there is any incorrect or inappropriate way when using the machine:
● Not used in accordance with design requirements;
● Operators and maintainers use it without training;
● Users change the contents of the design without authorization;
● Users don't pay attention or understand the rules of safe-using.
Every people who involving the use or maintenance of Low-speed
centrifuge should read and understand the using way and rules of
safe-using of this manual.
You must totally enforce the following rules to avoid accidences:
The "Manual" is part of accessories of “Low-speed table-top centrifuge”, it must be put together with the
machine for the operator to check. Low-speed centrifuge of general air-cooled is designed for clinical
medicine, biology, chemistry, genetic engineering, immunology and so on. The density of the separated
sample can not exceed 1.2g/cm ³ under the maximum speed, when the density of the sample exceeds
1.2g/cm ³, the maximum speed of the rotor must be reduced accordingly.
When Low-speed centrifuge is running (separating the sample or the rotor is rotating), please make sure
that nobody or any hazardous materials can be existed within 30cm away from centrifuge, and no materials
block the vent of the centrifuge.
The centrifuge will injure the operator or other staff or there's damage on the centrifuge and separated
sample inside if the user don't follow the following safety measures when operating the Low-speed Table-top
centrifuge:
● The centrifuge can't be used in the environment of corrosion or there is possibility of explosion because
the design of the centrifuge is neither anti-corrosion, nor is anti-explosion (proof);
● Do not use following materials in the centrifuge:
- Flammable and explosive materials;
- Strong chemical materials;
- Toxic or radioactive.
● For the separation of corrosive substances and pathogenic micro-organisms cells, please take effective
measures of seal in advance, and do the sterilization in time after separation. For more details, please
check from "issues of repair and maintenance".
● The internal part of the centrifuge will be damaged and the mechanical strength of the rotor will be weaken
when using it for separating corrosive materials. In this case, corrosive materials should be put in the
protective container.
1.1 Notes of operation
● Please ensure that proper rotor are installed tighten before the running of the centrifuge (separating the
samples)
● Don't open the door manually if the centrifuge is still running (rotor is turning) or the rotors don't stop to
turn.
● The accessories of Low-speed centrifuge should be provided by Our company. For some general
accessories, such as glass and plastic containers used for the separation should be confirmed to meet the
requirements. It shall conform to requirement of the use of maximum turning speed and maximum
centrifugal force of the corresponding rotor.
● Do not use centrifuges or separate the sample with the door is open.
● The replacement of mechanical accessories and electronic device of centrifuge should be implemented by
designated person of Our company.
● When operators are using the centrifuge, they shall choose rotor with appropriate load and shall not use
the rotor overload;
● Check rotor regularly. Stop to use it once there is obvious corrosion or obvious damaged signs on the rotor;
● After a period of using, Please do the maintenance according to the rules of "cleansing and disinfection".
