Sweat-Chek™ Sweat Conductivity Analyzer

Discovery Diagnostics, Canadian distributor for Wescor's Sweat-Chek™ Sweat Conductivity Analyzer, diagnostic equipment providing electrical conductivity values for laboratory diagnosis of cystic fibrosis

 Wescor Model 3120 Sweat-Chek™ Sweat Conductivity Analyzer. Simple direct injection of six microliters of sweat from the Macroduct™ sweat stimulation & sweat collection system provides electrical conductivity values for laboratory diagnosis of cystic fibrosis. The temperature of the conductivity cell is automatically maintained, and calibration check is simply performed.
Hemotology Slide Stainer Cytocentrifuge Product Details
The Sweat-Chek™ Sweat Conductivity Analyzer is accepted by laboratory professionals worldwide as the standard for testing collected sweat. It makes accurate conductivity measurements on less than 10 microliters of sweat in about 10 seconds.

Dr. Lewis E Gibson, reports that "If this machine is kept clean, it gives results that are every bit as reliable as an analysis for sodium or chloride."

Dr. Gibson, co-originator of the venerable Gibson-Cooke sweat testing method, recommends that conductivity values ranging up to 60 mmol/L can be considered normal. Readings higher than 80 mmol/L are considered to be positive for Cystic Fibrosis. >Combined with the Wescor Macroduct® system for sweat stimulation and sweat collection, the Sweat-Chek™ Analyzer is becoming the new world standard for Reliable laboratory diagnosis of cystic fibrosis.
