Transmission Cell Holder
The optional transmission cell holder permits measurement of liquids in
10-mm, 20-mm, 33-mm, or 50-mm transmission cells.
To install it, slide the
transmission cell holder
into the transmission
compartment at the
center, widest part of the
transmission
compartment. To use the transmission cell holder,
position the holder inside the transmission compartment so
that the flat end of the holder is aligned with the rear wall
of the transmission compartment. The slanted end will be
at the sphere wall at the front of the compartment. Ensure
that the holder is flush against the sphere wall. Depress
and turn the captive screws clockwise. If the holder is slightly off-line, reposition it so that the screws
align properly in the holes on the floor of the transmission compartment.
You may use the holder for measurements in either total or regular transmission by following the
software prompts to standardize in the desired mode. If you are using total transmission (TTRAN),
place the cell at the
sphere opening at the front of the transmission compartment. If you are using
regular transmission (RTRAN), place the cell at the lens port at the rear of the transmission
compartment.
Transmission Cells
The transmission cell option provides an optically-clear
glass cell with a fixed path length of 50 mm, 33 mm, 20
mm, or 10 mm. Transmission cells are recommended for
transmission measurements of lightly-pigmented materials
and some reflectance measurements. When used for
transmission measurements of liquids, the cell filled with
distilled water or another clear solvent should be used
