Use of Reagent Powder Pillows
Dry powdered reagents are used when possible to minimize problems of
leakage and deterioration. Powders are packaged in individual, pre-
measured, polyethylene "powder pillows." Each pillow contains enough
reagent for one test and is opened easily with nail clippers or scissors;
see Figure 10.
Using PermaChem Pillows
For best results, slightly tap the pillow on a hard surface to collect the
powdered reagent in the bottom. Then:
1. Tear across, from A to B, holding the pillow away from your face.
2. Using two hands, push both sides toward each other to form a spout.
3. Pour the pillow contents into the sample cell and continue the
procedure according to the instructions.
