Part Number 400640

The Lovibond® 400640 Powder Cell Holding Fixture is designed to hold a cell for liquid or powder measurement. The fixture is designed specifically for an Optical Circular Sample Cell (400740). The cell is enclosed in a black chamber which prevents ambient light from affecting the measurement. The fixture attaches to Lovibond® Models RT300, 400 & 500 Spectrophotometer Series. The spectrophotometer must be mounted in the Lovibond® 400620 Benchtop Stand.

Measurements taken with the Cell Holder and Optical Sample Cell are intended for relative measurements comparing a standard and a sample batch. The fixed errors resulting from the thickness of the glass or plastic and translucency of the samples prevent comparison to an absolute reflectance standard.
