Weighing Accuracy in Pharmacy
- Class A prescription balances are mandatory for all compounding procedures.
- These balances have a sensitivity requirement (SR) of 6 milligrams or less, both unloaded and loaded with 10 grams in each pan.
- Errors greater than 5% should be avoided.
- For minimal weighing error, weigh at least 120 milligrams. (5% error in 120mg = 6mg)
- Most Class A balances have a maximum weighing capacity of 120 grams.
