Cylindrical Cell Holder
This option provides a holder for 27-mm to 30-mm (OD) cylindrical sample tubes at the instrument
transmission port. This holder may be used for measurement of transparent liquids in cylindrical glass
tubes with 20-mL, 40-mL, or 60-mL volumes (not sold by HunterLab).
Complete the following steps to install and use the tube holder:
1. Place the tube holder in the transmission compartment, orienting the holder so that the slotted
portion of the base faces away from the sphere with the flat side at the sphere. The open viewing
hole in the holder must be centered over the hole in the sphere.
2. Locate the appropriate two mounting holes in the transmission compartment floor and fasten the tube
holder to the instrument using the two thumb screws provided.
3. Standardize the instrument in TTRAN mode using the large area of view and 1.00” (25.4-mm) port
size. When prompted to read the black card, slide it between the tube holder and the transmission
port. Use a tube of the type you will be using for samples filled with distilled water (for water
solution samples) or a clear organic solvent (for organic solution samples) as your standardization
blank.
4. Remove the blank liquid and fill the glass tube with sample and then insert the tube into the open
column in the tube holder. If needed, adjust the ball detent screws until the tube is held snugly in
place. Read the sample.
