Project Background:

In chemical R & D laboratories, precision weighing at the milligram level is the basis for many experiments. However, the dried chemical reagent bottle is easy to accumulate static electricity due to handling and friction, resulting in continuous drift and difficult stability of the reading of the high-precision electronic analytical balance. This electrostatic interference not only directly affects the accuracy of weighing data, but also slows down the development process, and even causes a double waste of reagents and time.

Cause analysis:

The reason is that the electrostatic charge forms an additional electric field between the reagent bottle and the balance, and the additional electrostatic force generated interferes with the normal operation of the balance weighing system, resulting in inaccurate and unrepeatable measurement results.

Solution:

In order to solve these 1 problems, a space static eliminator can be installed around the electronic balance. The device uses high-voltage electric field ionization technology, without wind assistance, can make a large number of positive and negative ions in the air. Under the action of electric field, these ions can quickly cover the reagent bottle and weighing area, effectively neutralize the static electricity on the surface, eliminate interference from the source, and create a stable static-free environment for weighing.

Implementation effect:

The practical application proves that after installing the static eliminator, the balance reading immediately returns to stability, and the reliability of the experimental results is significantly improved. This not only ensures the accuracy of the data, but also reduces the experimental rework and material loss caused by weighing errors, the overall research and development efficiency has been greatly improved, and has become a simple but key technical guarantee in the chemical experiment.
