Background Description:

In drug development and quality control, electronic balance with one-in-ten-thousandth precision is often used to weigh trace drug powder. Drug powder can easily generate and accumulate static charge due to friction and transfer, resulting in serious weighing interference.

The specific performance is as follows: the powder is electrostatically adsorbed on the weighing spoon, resulting in residual loss; More importantly, the electrostatic field formed between the powder and the balance by the electrostatic charge causes the balance reading to drift and jump for a long time and cannot be stabilized.

Solution:

In order to solve this problem, the laboratory introduced the space static eliminator as the core measure. The device achieves full coverage and neutralization of static electricity in the weighing area (beaker, conical flask, weighing paper, tweezers, medicine spoons, gloves,) and the operator's clothing through wind-free static elimination technology. It can accurately eliminate the static electricity on the surface of the drug powder and the container. What is especially important is that the working process does not require airflow assistance, which fundamentally eliminates the risk of loss or cross-contamination of trace samples due to airflow disturbance, and provides an ideal static-free environment for high-precision weighing.

Implementation effect:

After the implementation, the powder static electricity is quickly neutralized, the adsorption and floating phenomenon is basically eliminated, and the balance reading is rapid and stable. The repeatability and accuracy of weighing results are significantly improved, which effectively guarantees the research and development process and data quality, and reduces sample waste and experiment redo caused by weighing errors.
