GLASS ENCAPSULATED CALIBRATOR SOLUTION 
FOR SWEAT-CHEKª CONDUCTIVITY ANALYZER 
For In Vitro Diagnostic Use 
Intended Use 
WescorÕs CALIBRATOR solution is for calibration 
of the Sweat-Chek Sweat Conductivity Analyzer. 
Product Description 
WescorÕs CALIBRATOR solution is liquid, ready to 
use, and requires no reconstitution or dilution. Each 
ampule contains 0.75 mL of NaCl solution, at 90 
mmol/L molarity. 
Warnings and Precautions 
No special precautions are required in handling the 
product other than those routinely used in the laboratory. 
Storage and Stability 
1. CALIBRATOR should be stored at room temperature. 
2. Each ampule contains 0.75 mL of solution. This volume 
adequately mitigates evaporative concentration 
for a few hours after the ampule is broken. Ampules 
are intended for one-time use only. 
Instructions for Use 
1. Invert gently to ensure homogeniety of the contents. 
2. Before opening, flip the neck of the ampule or tap 
the ampule bottom against a hard surface to clear 
solution from the neck. 
3. Place the ampule in the ampule breaking position of 
the organizer. 
4. Place the safety sleeve over the neck of the ampule. 
5. Holding ampule organizer down against the counter, 
grasp the neck of the ampule firmly between thumb 
and forefinger and snap the neck off. 
6. Sample directly from the ampule, using a fresh 
Sweat-Chek take up tube to avoid contamination of 
the solution. 
7. Follow procedures in UserÕs Manual to assay 
CALIBRATOR solution. 
Expected Values 
The Sweat-Chek conductivity cell has an extremely 
stable response characteristic that is virtually linear 
through the critical range from 75 to 110 mmol/L. The 
main purpose of calibration is to ascertain that the conductivity 
cell temperature is within the correct range and 
that the electronics are otherwise functioning normally. 
If the conductivity cell is free of residual salt or water, a 
reading within ± 2 of the labeled value of 90 mmol/L 
indicates overall performance to a very high level of 
confidence. If the reading falls outside of this range, 
follow the instructions listed in the UserÕs Manual for 
calibrating the instrument.
