Increase Weighing Accuracy by Eliminating Electrostatic Charges
Electrostatic charges on weighing containers and samples can result in false readings or instability as they create attractive and repulsive forces. The ION-100A is designed to be used in conjunction with an OHAUS balance to neutralize electrostatic charges that can lead to inaccuracies.


Standard Features Include:

  • Increases the Accuracy of Lab Measurements
    The ionizer neutralizes the electrostatic charge between the test tube and the balance,
    increasing the accuracy of measurements—particularly with low-volume samples.
  • Fan-Free Technology Neutralizes Static with No Sample Disruption
    ION-100A’s electrodes generate positive and negative ions that are delivered through
    fan-free technology that doesn’t disturb fine samples.
  • Compact and Versatile Design
    The ionizer can be adjusted for optimal alignment with the balance, and its small footprint
    takes up minimal space. The durable electrodes can be easily replaced and have an
    operating life of 15,000 hours.

How does static affect your weighing results?
When the ambient relative humidity (RH) is below 45%, insulators such as plastics are typically charged with static electricity.
This can cause errors of several milligrams, and impact weighing results. For example, powdery substances with a static charge might stick to to the edge of the test tube—making it difficult to weigh and to clean up.

DC Corona Method
Ionizer ION-100A uses the DC Corona Method to eliminate static charges. Two polarity electrodes continuously generate positive and negative ions. These ions are attracted to ions of the opposite polarity, neutralizing the sample within a charged environment. Eventually, 99% of the static charge will be removed from the
container. The most effective area is 10–40 cm away from the charged body.

DC Corona Method

  • Two electrodes work simultaneously to generate 1*106 /cm3 bipolar ions
    Covers a wide range of effective area
    Ionization occurs in areas up to 40 cm away from the charged object
  • Fan-free technology
    No need to worry about fine samples such as powders being blown away
  • Conventional Method
    One discharge needle generates a single type of positive or negative ions at intervals
    Static is removed most effectively in areas closest to the electrode only
    Requires a ventilator or an electronic fan to blow ions on to the sample
