Sweat-Chek Analyzer Model 3120

Sweat Chek is the dedicated sweat conductivity analyzer for use with the Macroduct® Sweat Testing System.

Sweat samples are collected in Macroduct using the normal procedure. A syringe is attached to the end of the microbore tubing before the tubing is uncoiled and severed from the collector body. The end of the microbore tube is then attached to the inlet nipple of the Sweat-Chek conductivity cell.

A separate length of clean microbore tubing is attached to the outlet nipple of the cell to act as a take-up reservoir.

The specimen is transferred into the cell by moving the syringe plunger. When the specimen contacts both cell electrodes (less than 10 microliters are required), the conductivity of the specimen is measured, converted to equivalent NaCl molarity, and the result displayed.
The conductivity cell is temperature-controlled for stable calibration and operation. A stable reading obtains in about 10 seconds as the specimen equilibrates to the cell temperature. The digital readout is calibrated in units of molarity (mmol/L) representing the molar concentration of a NaCl solution equivalent in conductance to that of the sample.

The specimen can be drawn back into the cell for repeat measurement, or it can be expressed into a storage cup for subsequent corroborative analysis by any microanalytical procedure including anion assay, cation assay, osmolality assay, or electrical conductivity if desired.
