Glutaraldehyde ChromAir Badge (380017-10)

ChromAir chemical exposure badges are a color indicating making them easy to use and perfect for monitoring personnel safety.

Quantity = 10 badges  *clips are NOT included*

Note: we are not able to ship these badges outside of the US

Shipping Note: We now only ship the Glutaraldehyde badges Monday – Wednesday 2nd Day air. Since we only ship them those days, they do not require a cooler pack for transport. But badges should be refrigerated after receipt.

Glutaraldehyde Information


Color change for Glutaraldehyde is from pink to violet.

The ChromAir Glutaraldehyde badge may be used for personnel or area monitoring for exposure times of 15 minutes.



Glutaraldehyde is a colorless liquid with an irritating odor. It has an odor threshold in the ppb level. Glutaraldehyde may be fatal if inhaled, swallowed or absorbed through the skin. Symptoms of exposure may include burning sensations, coughing, shortness of breath, headache, nausea and vomiting. To the best of our knowledge, toxicological, chemical and physical properties have not been thoroughly studied. OSHA and NIOSH STEL are 0.2 ppm. Glutaraldehyde is used extensively in the medical field. It is used in hospitals for cold sterilization of medical supplies and instruments.

Glutaraldehyde is also used as a disinfectant in urology, endoscopy and dental departments.


Principle of Operation

The ChromAir passive detector is a patented direct-read autogenic exposimeter. The monitor is constructed from five cells attached on one side to a flat indicator layer and on the other side to a series of different diffusive resistances. Glutaraldehyde vapor diffuses to the cells through the different diffusive resistances and reacts with the indicator layer, producing color change from pink to violet. The color produced on the indicator layer is a direct measure of the concentration in ppm. Visual color comparison is achieved by observing the formation of the violet threshold color on the individual cell and reading the corresponding concentration.

Direct Read Color Comparator Safety Monitor

Pictured above is the additional color comparator that is used for higher resolutions and accuracy (available for Carbon Monoxide, Formaldehyde, Mercury).


Operating Instructions

1. Remove the pouch from refrigerator and allow it to warm to room temperature.

2. Remove the badge from its protective pouch.

3. Enter all pertinent information on the I.D. label before monitoring is started (i.e. name, location, date and start time).

4. Remove the scavenger strip from the front of the badge.

5. For personnel monitoring, attach the badge near the user's breathing zone (i.e. collar) with the front side exposed to the surrounding atmosphere.

6. For area monitoring, attach the badge to a stand and mount in a centralized area with the front side exposed to the surrounding atmosphere.

7. Expose the badge 15 minutes.

8. At the end of the exposure period (15 minutes), return the badge to its original pouch and let stand for 45 minutes at room temperature to allow complete development of color. Read the badge no later than 3 hours after exposure.

9. At the end of the development period, locate the highest level cell with violet threshold color and read the corresponding average concentration from the scale.



The ChromAir STEL glutaraldehyde monitor should be refrigerated in its sealed bag at all times.
