Project Background:

In the fine operation of medical laboratory, the electronic balance with one ten thousandth gram precision is an important tool to obtain key data. However, in a dry environment, especially when the humidity is lower than 40%, the medical test tube is easy to generate electricity due to high insulation, resulting in continuous drift and beating of the balance reading during weighing, and the milligram weighing error significantly exceeds the standard, seriously affecting the reliability of the experimental results.

Cause analysis:

The root cause is that the electrostatic charge accumulated on the surface of the test tube will produce unpredictable electrostatic forces between the balance, and this additional interference makes the true weight data masked. In order to solve these 1 difficult problems, the laboratory introduced a targeted solution-space static eliminator.

Solution:

At the heart of the solution is the deployment of a windless space static eliminator. By generating a balanced group of positive and negative ions, covering the weighing area silently and without airflow disturbance, it can actively neutralize the electrostatic charge on the surface of test tubes and other items, fundamentally eliminate the interference of electrostatic field, and create a stable "no electrostatic" environment for precision weighing.

At the same time, the laboratory is supplemented by systematic measures: the environmental humidity is accurately controlled at 45%-60% RH; To ensure that the electronic balance itself is well grounded; And standardize the operation process, requiring personnel to wear anti-static equipment, before the operation to release human body static electricity.

Implementation effect:

After using the space static eliminator, the static electricity on the surface of the medical test tube is quickly and effectively neutralized, the balance reading is rapid and stable, and the repeatability and accuracy of the weighing results are significantly improved. This ensures the reliability of experimental data and reduces experimental rework and sample loss due to weighing errors.
