3 General requirements   
3.1 Structure
The typical centrifuge bowl structure is shown in figure 1.
Each connection position (excluding protective case) of the centrifuge bowl shall be able
to withstand static tension of not less than 15N for 15s.
4.5 Friction heat
When the centrifuge bowl is tested based on Annex B B.2, the water temperature shall not
exceed 37°C centigrade.
4.6 Noise
When the centrifuge bowl is operated under 7 000 r/min, if sound level meter (A-weighting)
is used to measure four points when the distances of front, back, left and right position are
1m away the center of the centrifuge bowl, the average noise shall not exceed 70dB.
Note. when centrifugal machine is idling during test, the average noise shall not exceed
4.7 Blood residues
When the centrifuge bowl is tested based on Annex B B.3, residues inside the bowl shall
not exceed 5.0 mL.

When test is conduced based on Annex C, the separation plasma hemoglobin content
shall not exceed 60mg /L.
4.9 Protective case
Protective sleeve which is firm and easy to be disassembled shall be equipped at the inlet
and outlet of the centrifuge bowl. The protective sleeve shall be able to keep cavity sterile
in the bowl.
4.10 Inlet and outlet of the centrifuge bowl
The inlet and outlet of the centrifuge bowl shall be matched with the centrifuge bowl
interface of plasma tubing as specified by YY 0326.2.
Note. The suitable inlet and outlet are external-cone joints with root diameter of 8mm and
conical degree of 1.40.

Annex A
Measurement method of fine-particles limits
A.1 Principle
The method is to simulate the use state of the centrifuge bowl; collect the particles in
eluent through internal cavity surface of centrifugal rinse bowl; count it to evaluate the
particle pollution.
A.2 Test instrument and solution
A.2.1 Special centrifugal machine. matched with the centrifuge bowl; centrifugal machine
can achieve centrifugal rotation speed of 7000 r/min.
A.2.2 Special particle counter. equipped with mixing system. Sampling amount for one
time is 100 mL; it can count 15 ~ 25 um particles and particle of more than 25 um at the
same time.
A.2.3 Rinse solution. 9g/L sodium chloride solution, filtered by microporous membrane of
0.45um (it’s applicable to resistance method particle counter) or distilled water (it’s
applicable to light resistance method particle counter.
A.3 Test steps
A.3.1 Eluent preparation
Inject 200mL of eluent from the inlet of the centrifuge bowl; place the inlet and outlet into
the special centrifugal machine with protective sleeves. The rotation speed of centrifugal
machine is adjusted to 7000r/min; turn up and down for 5 times after centrifuging for 5
A.3.2 Particle inspection
Take 200mL of eluent out from the outlet of the centrifuge bowl; put into the sampling cup
of particle counter; count it with pa......
