What is GMP in Weigh & Dispense?

GMP compliance in weighing and dispensing ensures that:

• Correct material is weighed

• Correct quantity is dispensed

• All activities are documented, traceable, and auditable

• Risks of mix-up, contamination, and human error are minimized

This is critical for pharmaceutical, biotechnology, food, and chemical manufacturing.
