StaticMaster 1U400 Self Powered Alpha Ionizer – 1 Inch – 500 uCi


Availability: In Stock


Installation inside equipment, narrow webs, small trimming jobs, analytical scale and precision weighing, semiconductor, microscopy, microtome sectioning, DNA process. Any handling of small items that will be adversely affected by static charge.

Staticmaster® 1U400 Ionizing Cartridge. Similar to the 2U500 and with a square configuration, the 1U400 has the same static eliminating potential in the smallest configuration we offer, measuring only 1.02″ x .93″ x .24″ thick. Please feel free to contact us about the unique applications of the 1U400.

Staticmaster® Ionizing Cartridges are the only self-powered
static eliminators available today. Their small profile makes
them an ideal solution for in-balance static elimination.
They eliminate the problem of “fly-away” powders and
inaccurate measurements in analytical and precision
weighing applications as well as semiconductor, In-Tool,
glovebox and forensic environments.
These ionizing cartridges utilizing NRD’s proven alpha
ionizing technology can be easily mounted within a balance
chamber, assuring quick and accurate measurements. They
offer “zero-volts balance” technology, which means that
they can effectively remove all of the static charge present
in your media and samples, ensuring accurate weighing.
Staticmaster Ionizing Cartridges are available in four
variations including, Model 2U500, Model 1U400, Model
1U200 and Model 1U200S.
Each Ionizing Cartridge offers optional accessory, Model
5060 Grounding Kit
, to provide a faster static elimination
time for your process. Extensive testing has shown
that adding the Grounding Kit to the alpha ionizer can
significantly increase the performance of these advanced
static eliminator solutions.

So small as to fall below minimum requirements for regulation, this unique unit may be used without the strict requirements of the US Nuclear Regulatory Commission regulations and OSHA regulations (29 CFR 1910.1096) that cover the use of ionizing radiation in general industry. Even without needing to meet this requirement, since you become a General Licensee by receiving our devices, you shall be deemed to be in compliance with the OSHA requirements with regard to the use of our nuclear static eliminator, provided that you use them in accordance with the instruction sheets provided to you with these devices.

Often used in accurate laboratory scale weighing operations, this static removal tool can be used at microscope or in tool process to solve static control in small areas.

A self-powered static eliminator with optional pulsed Alphaboost Power Supply to extend coverage of over 10 times the normal 3cm distance. When used in laminar airflow the distance is extended to 36 inches or more. Its small profile makes it an ideal solution for in-balance ionization, and it is inherently balanced to zero volts – which helps ensure thorough static removal for accurate weighs every time.

By choosing the 1U400 ionization source for you Alphaboost configuration, you will save annual cost for replacement and due to the micro size, eliminate the regulation oversight normally associated with nuclear devices.

United States Nuclear Regulatory Commission § 30.15 Exemption (2)(i) Static elimination devices which contain, as a sealed source or sources, byproduct material consisting of a total of not more than 18.5 MBq (500 µCi) of polonium-210 per device.

Note on Ion Source

All NRD ion sources are encapsulated in precious metals by means of a patented process. This results in a static eliminator which resists oxidation, solvents, heat, cold and vibration.
