Colitag™ provides unparalleled flexibility and accelerated testing speed in determining and detecting E. coli and total coliform for maximum lab efficiency. Eliminate time-consuming confirmations and obtain accurate test results within 16-48 hours.
Colitag™’s 3 Most Advance Features
16-48 Hour Testing Window
Colitag™ is an enzyme substrate test that offers unparalleled 16-48 hour total coliform and E. coli determinations. This method detects the presence of 1 MPN of total coliform or E. coli bacteria per 100mL water sample.
Colitag™ provides maximum flexibility by extending incubation times so that technicians can read results at their convenience, anytime from 16 to 48 hours.
Improved Laboratory Efficiency
Eliminate the need for time-consuming confirmations required by other enzyme substrate media that emit less-intense fluorescence. Colitag™’s bright blue fluorescence indicates a positive E. coli sample for clear determinations.
Determine the Presence or Absence of Coliforms and E. coli in 5 Easy Steps
Watch the quick how-to video and guide steps in performing P/A test with Colitag™.
1. Aseptically add the contents of one Colitag™ packet to a 100 mL water sample in a sterile vessel.
2. Secure vessel top and agitate to begin dissolution. Shake periodically until dissolved.
If the sample is not already at 33-38°C, then pre-warm the sample by placing vessel in a 44.5°C water bath for 7 to 10 minutes or alternatively 35°C for 20 minutes.
4. Incubate sample at 35 ± 0.5°C or according to local regulation temperature for the remainder of the desired incubation time; 16 to 48 hours.
5. Visually examine results.
