Chloro-Chek® Chloridometer

The ChloroChek Chloridometer was designed to work with the Macroduct Sweat Collection System for analyzing sweat chloride for the laboratory diagnosis of cystic fibrosis.

ChloroChek is easy to operate and gives results in less than 20 seconds. Simply pipette in a 10 microliter sample of sweat and get a results of the display instantly.

ChloroChek has an intuitive touch-screen interface with simple prompts and leads the operator through the entire process of measuring chloride levels of sweat samples.

Electrodes are simple to install and remove for cleaning. Sweat controls are available with 3 levels to insure the highest level of quality control procedures for regulatory requirements.

Macroduct® Sweat Collection System

Standardized sweat testing for the laboratory diagnosis of cystic fibrosis.

The Macroduct system is the Webster Sweat Inducer, and the Macroduct Sweat Collector. Together they have revolutionized the laboratory sweat test for cystic fibrosis, and have brought early intervention to thousands of CF patients around the world. The heart of this system is simplicity.

The 1959 pad absorption method of Gibson and Cooke, which introduced pilocarpine iontophoresis for sweat stimulation, is generally regarded as the reference method for sweat testing. Although generally free of intrinsic error, the method is long, tedious, requires a great deal of technical skill to administer and therefore invites human error. The Macroduct System has forever eliminated the errors inherent in all previously used methods and offers an easily standardized test.

The Webster sweat inducer and Macroduct sweat collector produce a pure specimen of eccrine secretion for analysis by using either chloride analysis with a Chloridometer or total electrolyte analysis with the Sweat-Chek Analyzer. These instruments provide simple and accurate analysis of the specimen. Together with the Macroduct Sweat Collection System, they have become the world standard, used by thousands of labs worldwide.

Macroduct is approved for sweat stimulation and collection by the U.S. Cystic Fibrosis Foundation, and is rapidly replacing the pad absorption method where laboratories want standardized tests. With the Macroduct system, sweat testing is both accurate and simple.

Nanoduct® Neonatal Sweat Analysis System

The Nanoduct Neonatal Sweat Analysis System simplifies the sweat test and for the first time makes possible reliable laboratory diagnosis of cystic fibrosis in the first days of life.

The compact and ergonomic Nanoduct updates the classic method of inducing sweat by pilocarpine iontophoresis, followed by continuous-flow analysis using the unique Nanoduct sensor cell. Results appear quickly on the display.

Nanoduct has sensitive and robust self-diagnostics for complete monitoring of all system functions and now includes computer and printer interface capability. To record more detailed information or to capture the results in a computer file, Wescor’s Nanoduct Lab Report software for Windows® combines user-provided information with measurement results directly from the Nanoduct to a printable and/or savable report.

Sweat-Chek™ Analyzer

Dedicated analyzer for the Macroduct System for total electrolyte analysis of sweat samples.

Interfacing perfectly with Macroduct, Sweat-Chek brings simplicity and economy to the analytical phase of the sweat test.

A truly practical sweat testing system is now within the means of small hospitals, local clinics, or private practitioners. Larger clinics and hospitals need no longer tie down personnel and resources with the tedious and error-prone pad absorption procedure when the Wescor method is so simple, safe, and accurate! While clinicians have traditionally used sweat chloride or sweat sodium ion assay, sweat conductivity is a proven method of sweat analysis. It is a simple and reliable indicator to confirm or exclude the physician’s clinical diagnosis of cystic fibrosis.
