Bacterial contamination

When bacteria levels need to be controlled, reagent grade types should be further classified as follows:

	Type A	Type B	Type C
Maximum heterotrophic bacteria count	10/1000 mL	10/100 mL	100/10 mL
Endotoxin, EU/ml^B	0.03	0.25	not applicable

*pH is not a significant indicator when comparing ionic contamination.
