Sample Cup Set for Translucent Liquids
This set provides a device for holding powders, pellets, granules, and translucent
liquids at the sample port. It includes a 64 mm (2.5 inch) glass sample cup, plastic
ring and ceramic disk set, special port plate insert, and sample cup cover
The ring and disk set are provided for translucent liquids, transparent liquids, and
semi-solids where the path length is related to color concentration and must be
fixed. First, the sample cup port plate should be installed to hold the sample cup in
the proper position. Place the ring inside the sample cup and fill the cup with sample
to a level above the ring. Then place the ceramic disk on top of the sample (until it
rests on top of the ring) with the white portion facing the sample. Cover with the
sample cup cover to exclude external light. Measure the sample at the sample port
through the glass bottom of the sample
cup with the instrument in the port-up
orientation . .

port insert by pulling it out of the port insert retainer. Replace it with the sample cup
port insert, then standardize the instrument.
