Answer:

These two HunterLab 2mm transmittance cells share the same basic design. The D04-1015-323 2mm Flow Cell has separate inlet and outlet ports; the D04-1015-179 2mm Manual Loading Cell has a single capped port for loading and draining the cell.

This thin cell is very robust (does not break easily) with a large viewing area that does not compromise the performance of Hunter Lab sphere instruments in making repeatable color measurements. It comes in two formats, flow and manual loading, that meet the needs of most clients for a thin path-length cell design. It is easy to flush clean. It is particularly useful in measuring highly saturated, water-based transparent liquid samples.

The path-length for both is 2mm with a tolerance of +/- 0.2-mm. This means the normal path length can be anywhere from approximately 1.80mm to 2.20mm.

If the variation in path-length is an issue, the user can select one 2mm cell as a reference and incorporate a bias offset for the other cells relative to the reference cell. This can be incorporated as a Custom Formula field in EasyMatch QC.
