2.2 overview
Low speed frozen centrifuge is a high-speed desktop frozen centrifuge used for
routine analysis in medical laboratories, biochemical and molecular biology research,
and industrial laboratories. It can be widely used in clinical medicine, biology,
chemistry, genetic engineering, immunology, and other fields. It is a conventional
instrument used for centrifugation and sedimentation in laboratories. This machine is
equipped with 5 types of rotors (see Table 1: Rotor Types and Technical Parameters
for details).
2.3 Introduction to Equipment Structure
This equipment consists of refrigeration system, door cover system, cavity
system, drive system, rotor system, base system, power supply system, control system,
display system, and alarm system components.
2.3.1 The refrigeration system includes compressors, condensers, fans, etc.
Adopting a powerful fluorine-free high-efficiency refrigerant R134a, the temperature
control range is between -20
℃
and+40
℃
, and it can also quickly precool the
rotating head in a stationary state. When the centrifuge door cover is opened, the
refrigeration system will still ensure constant temperature operation at the set
temperature to avoid icing in the rotor chamber.
2.3.2 The door cover system includes door cover, door hinge and damping gas
spring, door lock, door alarm, emergency door lock mechanism, etc. The door hinge is
located inside the rear of the rack, and the door lock is in front of the rack. Only when
the door lock is locked can the centrifuge be started, otherwise the door alarm system
will work (the buzzer will sound) and the machine will not start.
To open the door cover, simply press the open button on the machine control
panel. When the door cover is opened to a certain height, the door hinge and damping
gas spring can support the door cover.
If there is a power outage or failure of the door opening key, and the sample must
be taken out in a timely manner, it is necessary to use the accompanying tool to insert
it into the emergency door opening hole and rotate it clockwise for one and a half
turns until the door cover is opened.
