CAUTION - Addition of excess amounts of liquid (overfilling) to Cell or Filter
Concentrator will result in the fluid being “spun out” during centrifugation.
Spin the Sample
CAUTION - Never operate the CytoFuge 2 without the rotor cover 5 in place.
1. Screw on the rotor cover5.
2. Close and latch the centrifuge cover.
3. Select the time and speed (See Table 1)
4. Press start button.
Table 1: CytoFuge 2 Speed and Time Settings. CytoFuge 2 operating parameters generally
depend upon the size and specific gravity of the cells to be concentrated onto the microscope slide.
The operator should experiment with different settings to achieve optimum performance for specific
applications. The following are general guidelines:
Application Speed Range Time Range
Cytology 600 to 1000 rpm 2 to 4 minutes
Hematology 1000 to 2200 rpm 4 to 8 minutes
Microbiology 1600 to 4400 rpm 4 to 10 minutes
For fragile cells, reduce speed.
For wet preparations, reduce time.
For small particle (e.g. bacteria), increase speed and time.
