REACTASTICK™ BY CHEMSEE
Rapid Colorimetric Screening for Food and Beverages
When a sample needs a prompt chemical check, ReactaStick™ dipsticks provide a visible color response without an electronic reader. Choose from seven individually sold products for formaldehyde, chlorine, hydrogen peroxide, borax, nitrate, nitrite and sulfide.
Food manufacturers, quality-control teams, inspection programs and commercial laboratories can use ReactaStick to screen incoming ingredients, check process samples and investigate suspected contamination. The visible response helps identify samples that warrant further testing, whether you are making occasional checks or running a recurring screening program.
Simple colorimetric screening: prepare your sample, dip for 5 seconds and compare the color at 3 minutes. One shared testing approach, matching reference cards and illustrated instructions help you put the selected detector to work.

Ranges show the color comparison scales for prepared samples; sensitivity denotes the first positive reference level, with peroxide specified at 0.1%.
* The nitrate detector also detects nitrite.
Simple Screening in Three Steps
1 · PREPARE
Prepare your sample
Prepare a liquid sample using the illustrated guidance for your detector.
2 · DIP
Dip for 5 seconds
Bring the sensing area into contact with your prepared liquid sample.
3 · COMPARE
Compare at 3 minutes
Read the visible response against the matching color chart—no electronic reader required.
Six products offer semi-quantitative color comparison; hydrogen peroxide provides a simple None/Positive result. Matching reference cards and illustrated instructions are included with each product.
