Description

How Does it Work?

Colitag’s strength lies in its ease of use. Simply add Colitag to your 100ml sample, incubate for between 16 & 48 hours, use a simple visual check for coliforms in the first instance, then a fluorescence check to determine E.coli bacteria presence.

What about Controls?

To make a blank, dissolve one Colitag powdered test of the same lot being used for samples into 100mL sterile water. The blank may be used immediately or incubated along the test samples. Bacterial control strains should be inoculated individually by transferring a loopful of fresh non-selective liquid culture into 100mL of sterile water mixed with the contents of one Colitag packet. This process is essential for ensuring the accuracy of your water bottling equipment tests.
