Coliform/E. coli Results in 18 Hours

Colilert-18 is a test used for the detection of coliforms and E.coli in drinking water that gives you results in just 18 hours.

With Colilert-18, you can:
  • Read afternoon samples the next morning—before the next day's samples arrive
  • Lift boil water alerts in 18 hours
  • Provide results in record time for real estate, new well, and new construction samples
  • Read Friday samples early Saturday, leaving the rest of the weekend free

Colilert-18 Benefits

Easy
  • Ease of use simplifies training.
  • Unit-dosed packaging eliminates media preparation.
  • No repeat testing due to clogged filters or heterotrophic interference.
  • Quality Control (QC) procedure can be done in 15 minutes.
Rapid
  • Under one minute hands-on time.
  • Detects coliforms and E. coli simultaneously in 18 hours or less.
  • No confirmations needed.
  • No glassware cleaning or colony counting.
Accurate
  • Identifies E. coli specifically, which eliminates unneeded public notification due to Klebsiella pneumoniae.
  • Suppresses up to 2 million heterotrophs per 100 ml.
  • Eliminates the subjective interpretation found in traditional methods.
  • Detects a single viable coliform or E. coli per sample.
Economical
  • 95% less equipment costs than membrane filtration (MF).
  • Minimizes evening and weekend work.
  • Up to 12-month shelf life at room temperature.

1. Presence/ Absence
Add reagent to sample and incubate 24 hours at 35°C

Read results. Colerless = negative
Yellow = total coliforms
Yellow/fluorescent = E.Coli

2. Quantification
Add Reagent to sample and mix well

Pour into Quanti-Tray® (count from 1 to 200) or Quanti-Tray® (count from 1 to 2,419)

Seal in Quanti-Tray Sealer and place in oncubator for 18 hours at 35°C

  • Read Quanti-tray results.
    Yellow wells = total coliforms
    Yellow/Fluorescent wells = E.coli
    Refer to MPN table
  • Read Quanti-tray 2000 results.
    Yellow wells = total coliforms.
    Yellow/Fluorescent wells = E.coli
    Refer to MPN table
