Static and electrostatic charging can cause inaccuracies, greatly affecting sensitive balances like analytical, micro, and semi-micro versions.
Many tare vessels, especially plastic containers, are prone to electrostatic charging. Powdery samples then scatter or stick to the container from the static electricity. If the sample is toxic or harmful, this could be dangerous to the operator.
Discharge/neutralize your samples before weighing to ensure maximum security of the sample and user, and obtain more accurate measurements.
