⚫Do not place dangerous materials within 30cm of the centrifuge.
⚫Prepare all necessary safety measures before using samples that are toxic, radioactive or contaminated
with pathogenic micro-organisms. Use of these is at your own responsibility.
⚫If the centrifuge, rotor and accessories that have been contaminated by solutions with toxic,
radioactive or pathogenic materials, clean it according to the decontamination procedure as specified.
⚫If you require service at site, please sterilize and decontaminate the centrifuge in advance, and then
notify the service center the details of the materials and procedure.
⚫To avoid electrical shocks, insure hands are dry before handling the power cord or turning on/off the
power switch.
⚫For safety purposes, do not enter within 30cm around this centrifuge when it is in operation.
⚫While the rotor is rotating, never release the door lock.

strictly prohibited.
CAUTION
⚫This centrifuge must be located on a firm and level table.
⚫Make sure the centrifuge is horizontal before running.
⚫Do not move or relocate the centrifuge when it is running.
⚫If fluid spills in the rotor chamber, please promptly clean and dry with a dry cloth to avoid sample
contamination.
⚫Ensure to remove any objects and fragments of the tubes dropped inside the rotor chamber before
running the centrifuge.
⚫Cautions with rotor
(1) Always check for corrosion and damage on the rotor surface before using it. Do not use the rotor
if an abnormality is found.
(2) Do not set the speed beyond the allowable minimum speed of the rotor kits (rotor and adapters).
Make sure to run it below the allowable maximum speed.
(3) Do not exceed the allowable imbalance.
(4) Use the rotor and tubes within their actual capacities.

Table 12-2 Cleaning and sterilizing conditions for tubes
1) Cleaning PC tubes
PC material is low in chemical resistance against alkaline solutions. Avoid using neutral detergents with
pH higher than 9. Note that pH of some neutral detergents are still higher than 9 even if diluted according
to the manufacturer’s instructions. Use detergent with its pH between 7 and 9.

LCEN-401P
17
2) Autoclaving PA、PC and PP tubes
PA begins softening at about 120℃, PC and PP at about 130℃. Autoclave PA tubes at 115℃（0.7kg/cm2）
for 30 minutes, PC and PP tubes at 121℃（0.1kg/cm2）for 20 minutes. If a certain temperature is exceeded,
the tubes may be deformed.
When use a sterilizing chamber, please operate as follows:
(1) Place tubes in vertical position, mouths upward. If tubes are placed sideways, they may deform into an
oval shape due to gravity.
(2) Remove locking nut and lid to prevent from deformation or rupture.
(3) Wait until the sterilizing chamber cools down to the room temperature before removing tubes.
4)Conditions and life expectancy of tubes
The life expectancy of plastic tubes depends on the characteristics of samples, speed of the rotor used,
temperature applied and so on. When the plastic tubes are used for ordinary aqueous samples (pH between
5.0 and 9.0), their life expectancies are defined as follows.
Be operated at the maximum speed:
High quality tubes (PA、PC、PP): 30-50 operations
Ordinary tubes(PA、PC、PP): around 10 operations（Using in low speed can extend the tube life）.
Life expectancy of tubes also depends on the pretreatment conditions such as cleaning and sterilization,
lifetime can be cut down.
Notice: Do not use damaged or cracked tubes.
13. Calculate RCF
An RCF can be determined with the following calculation formula.
RCF=1.118×r×n2×10-5
r—rotating radius, unit: cm; n—rotating speed, unit: rpm
14. Returning and Disposal
14.1 Returning Devices
Before returning the device, a transport securing device has to be installed.
If the device or its accessories are returned back, in order to provide protection for people, the environment
and materials, it has to be decontaminated and cleaned before being shipped.

LCEN-401P
18
14.2 Disposal
Before disposal, the device must be decontaminated and cleaned to protect people, the environment and
property. When you are disposing of the device, the respective statutory rules must be observed.
