Sanitizer Test Strips – Extra High Level

LABTEK Services can now supply a range of high level test strips, for a range of popular sanitizers including QAC, Chlorine & Peroxide.

Extra High Level Chlorine Test Strip, 10000ppm

The Extra High Level Chlorine test strip tests levels of free chlorine in a solution, in steps of 0-1000-2500-5000-7500-10,000ppm, giving results in just seconds. This test strip is great for environments requiring high levels of sanitation/disinfection, such as hospitals.


  1. Dip a test strip into the solution for 1 second.
  2. Remove the strip and wait 30 seconds, then compare to the color chart within the next 10 seconds.

Extra High Level Peroxide, 5000ppm

The Extra High Level Peroxide test strip is calibrated at 0, 500, 1000, 2500, and 5000ppm, and gives results in 90 seconds. These strips are used to test concentration levels of Peroxide solutions used in cases where strong disinfection is needed.

This test strip is designed to work with solutions prepared from concentrated hydrogen peroxide only. It should not be used to test solutions made using “accelerated” hydrogen peroxide products. These type of solutions require specially formulated test strips.


  1. Remove one test strip from the vial. Do not touch the test pad with your fingers.
  2. Dip the test strip into the solution being tested for 1 second.
  3. Remove and do not shake the strip.
  4. Compare the test pad to the color chart after 90 seconds.

Extra High Level QAC Test Strip, 10,000ppm

The Extra High Level QAC Test Strip (Quaternary Ammonium Compounds) measures the range of 0-10,000 ppm in increments of 1000, 2500, 5000 and 10000 ppm, and gives results in just seconds. Check for higher levels of QAC when testing stronger solutions that kill pathogenic organisms, as opposed to testing for residual QAC with our Low Level QAC test strip, or our standard QAC Quick Response Test Strip.


  1. Remove one test strip from the vial, being careful not to touch the test pad with your fingers.
  2. Dip the test strip into the solution to be tested and remove immediately.
  3. Immediately compare the test pad to the color chart. It is very important for the accuracy of the results to read the strip immediately (the maximum wait time is 5 seconds).

Allergens – The Power of ATP Testing

EnSURE_teaser_2Since 2003 there has been a rapid and continued development in ATP Bioluminescence.

ATP Hygiene monitoring has been traditionally used for the verification of cleaning where it measures low level residual organic contamination. The most recent ATP System development ENSURE with SuperSnap was evaluated by Campden BRI and compared with other leading ATP Systems. The ENSURE device showed improved sensitivity and improved tolerance to harsh samples and chemicals 5 times more resistant to acid and 10times more resistant to akali than UltrSnap and is totally resistant to 1000ppm hypochlorite.

The enhanced sensitivity of SuperSnap makes it suitbale for high care cleaning verification and in the support of allergen cleaning programs where it has shown to detect food residues below those detectable by specific allergen tests.

Hence a super ATP test provides better evidence of cleaning verification than specific allergen tests and is more cost effective.
