ecautions
Before servicing the PerfectSpin 24 R refrigerated microcentrifuge for the first time,
p
l
ease
read
this entire service manual carefully. It’s also important to refer the operation manual about
how to operate the unit correctly. For your safety, please observe the following points:
1.1
Operation
Safety
P
r
ecautions
1. When using infectious, radioactive or toxic solutions which may pose health risks,
please observe the appropriate safety precautions.
2. Do not use this machine in a potentially explosive environment or with potentially
explosive chemicals.
3. Install the machine in location free of excessive dust.
4. Avoid placing the machine in direct sunlight.
5. Choose a flat, stable surface capable of withstanding the weight of the machine.
6. Install the machine in the room temperature 15~30°C, relative humidity 20~80%.
7. Do not install the machine in a location that blocks the air vents.
8. Make sure the power source conforms to the required power suppl
y
specifications.
9. To avoid electric shock, make sure the machine is plugged into a grounded electric
outlet.
10. Do not allow water or any foreign objects to enter the various openings of the
machine.
11. Switch off the power switch before cleaning or performing any service on the
machine, such as replacing the fuses.
12. The rotor and the rotor lid must always be installed securely on the motor shaft.
13. Always load the rotor symmetrically. Each tube should be counterbalanced by
another tube of the same type and weight.
14. To ensure sufficient ventilation, install the centrifuge with at least 30 cm of free
space on all sides, including the rear.
15. Repair should be carried out by Labnet International authorized service personnel
only.
16. Only use spare parts and accessories provided by Labnet Int. or an authorized Labnet
distributor.
Warning
Label:
Please be aware of the danger of electric shock.

Description
The PerfectSpin 24R is a refrigerated, microprocessor-controlled tabletop
microcentrifuge with rotor speeds up to 13,500 rpm. It is supplied with a 24 x
1.5/2.0
ml rotor for micro samples. The temperature range is from -10 to 40 ºC.
2.1.
Design
Block
Diagram
The unit is equipped with the Display/MCU Board PCB to control the function of lid
open/close, compressor ON/OFF and motor speed, etc. The Power Board PCB which
contains Motor Driver IC and MOSFET is used to supply power and control the brushless
DC induction drive Motor which contains a Hall sensor to detect the motor speed. Other
function controls are shown in Figure 1. Design Block Diagram.
