Cary 100/300 
The Cary 100/300 comes with a cell holder base and two single cell 
holders. These are shipped installed in the sample compartment; 
however, if removed, they can be reinstalled. 
To reinstall the cell holder base and cell holders: 
1  Open the sample compartment lid and remove the front panel. 
2  Loosen the two black screws at the back of the sample 
compartment and remove the black screw on the front right side. 
Note the position of the locating pin at the front left side of the 
sample compartment. 
3  Hold the cell holder base so that the black, solid section is away 
from you. Note the key holes at the back of the cell holder base.  
4  Carefully place the cell holder base in the sample compartment 
and slot the keyholes under the two raised black screws at the 
back of the compartment. The front of the cell holder base should 
fit over the locating pin. 
5  Tighten the raised black screws and also secure the black screw 
at the front right side of the compartment. 
6  Holding a cell holder so that the notched section is to the right 
(see Figure 2), carefully place the cell holder over the two 
locating pins on the cell holder base in the reference beam.
