Powder Cell Kit - Large
The Powder Cell Kit measures reflectance of powdered samples and pastes. It mounts in the standard sample holder against the reflectance port of the External DRA. The kit contains a pre-packed PTFE cell for use as a reflectance standard and an empty powder cell holder for sample measurements. Each cell has a quartz window and measures samples across 200 - 2500 nm wavelength ranges.
The powder cell holder is plunger operated to accommodate a range of sample volumes. The minimum practical volume is approximately 1000 mm3 (equating to a depth of 1 mm), and the maximum volume is approximately 5000 mm3. These volumes are dependent on the particle size and opacity.
