Ionizer (fan type) IZF10-X275

1. Objective To replace the competitor’s fan type ionizer, which Siemens currently uses. Customer Siemens Healthcare Diagnostics Inc. Application Eliminate static electricity (prevent static cling during alignment and delivery) of plastic cuvette (test tube) used for the hematology analyzer instrumentation. Plastic cuvette

2. Dimensions Competitor Volume reduce by 41%

4-1. Features Easy maintenance ・ Electrode needle can be cleaned easily (not available with competitor). Since enclosure of an electrode needle can be removed from ionizer, the needle can be cleaned without any adverse effect to operating environment of the ionizer. ・ Electrode needle can be replaced (not available with competitor). If the needle performance did not restore even after clean, it can be replaced to new one. Improving static electricity elimination performance ・ Static electricity elimination performance (actual) Static electricity elimination time: 2.0 secs Ion balance: 4.6 V (fluctuation)

4-2. Features Alarm function ・ High voltage irregularity Stop when high voltage applied, Indicate by LED, External output available ・ Detection of electrode needle contamination (not available with competitor) Indicate by LED 5. Progress ・ Evaluation started by Siemens from January, Final approval to replace the competitor in July, 2010.
