Biological Activity Reaction Test (BART)

 

Biological Activity Reaction Test (BART)

A simple yet effective method for monitoring the population size and/or activity of specific groups of bacteria. Results are obtained by observation after 2-8 days of room temperature incubation.

BART Biodetector

With BART, you can monitor for Iron Related Bacteria (IRB), Sulfate Reducing Bacteria (SRB) and Heterotrophic Aerobic Bacteria (HAB) - the three most important agents involved in biofouling. Other BART systems are described below. These bacteria can cause corrosion, clogging, fouling of the water, and increased hygiene risks, so it is important to have an easy and accurate method of determining their presence and level of activity.

Easy to use

The BART Biodetector requires no microscope, no laboratory, and no incubator! The test is done at room temperature in your office or treatment room, on a desk, shelf, or in a cupboard, and is viewed daily. Different microorganisms like to grow at different heights in a column of water to which nutrients have been added. BART biodetectors contain nutrients in the base of a column and a ball. The ball restricts the amount of oxygen entering the water column, so that aerobic organisms grow around the ball and anaerobic organisms grow deep down in the water column. By changing the nutrients in the base of the column, different organisms are encouraged to grow. BART determines presence and activity levels.

Easy to analyze

The time taken for a color change (reaction) to occur gives a measure of the population size and activity. A color change occurs in the BART tube as a result of the oxygen gradient diffusing from the bottom upward. The change of color indicates a presence of bacteria within that sample. Interpretation is provided with the kit.

The Test

Full instructions for the use of BART biodetectors are included with your purchase. Each individual test consists of:

 

  • Test vial with media and BART ball
  • Outer tube for spill containment, odor control, disinfection, and disposal

Coliform Testing Kit

4-3616

Total Coliform Test Kit for Drinking Water

Order Code: 4-3616

The Coliform Indicator Test Kit utilizes an easy-to-use, disposable 5-tube method to indicate the presence of Total Coliform Bacteria in a drinking water supply.


Product Details



4-3616-uv

Total Coliform/E. coli Indicator Bacteria Test Kit

Order Code: 4-3616-UV

The Total Coliform/E. coli Indicator Bacteria Test Kit (Code 4-3616-UV) includes five tubes, each with a nutrient tablet. The five tubes are inoculated with 10 mL of sample water each and incubated for 24 to 48 hours depending on the ambient temperature. A change in the color due to acid production and the formation of gas bubbles in the reconstituted gel indicates the presence of coliforms.
