How to load the Guard Bowl
1. Use an even number of specimens chamber
assemblies. Arrange them in the rotor so
that pairs of specimen chamber holder
assemblies are opposite pairs.
Caution: Place equal size specimen chamber holders in opposite
positions.
2. If there are an odd number of specimen
samples to process, maintain the rotor
balance by adding one specimen chamber
filled with water to pair with the last
specimen.
3. If all twelve specimen holder positions in
the rotor are not filled, additional pairs of
water-filled speci-men chamber holder
assemblies may be added as necessary to
keep the rotor balanced.

4. Make sure the cytochambers are placed in
the right position
