21.Centrifugation of materials with higher density 高浓度材料的离心
The rotors are designed to centrifuge substances up to a maximum mean homogenous density of 1.2
kg/ dm
3
when rotating at the stated speed. Denser substances must be centrifuged at lower speed.
转子的设计是用来在指定转速下分离最最大平均表观密度为 1.2 kg/ dm
3
的材料。对于密度更高
的材料,必须用较慢的分离速度。
The permissible speed can be calculated using the following formula: 可用下面的公式计算可允许
的速度。
e.g.: RPM 4000, density 1.6 kg/dm
3
比如 RPM4000, 浓度为 1.6 kg/dm

If in doubt you should obtain clarification from the manufacturer. 如果有疑问的话,您需要联系制
造商来确认。
22 Rotor Identification 转子识别
After every start of a centrifugation run the rotor utilised is identified.
在每次离心启动后,转子将会被自动识别。
After a change of rotor the drive switches off and the rotor code (R xx) as well as the maximum
rotational speed (n-max=xxxxx) of the rotor are displayed.
如果转子被更换过,发动机将会停止,同时转子编号及最大离心力等信息将会被显示出来。
转子更换后,要再次使用离心机,必须重新开启盖子一次。
转子更换后,若转子的最高转速低于设定值,则设定的转速将自动调整为转子的最高转速。
