Microbial identification and trending with ATP Test Kits

- serial dilution log growth
- colony forming units
- microscopy counts
All-inclusive results are available in minutes, providing enhanced monitoring capabilities for superior control of microbes in your process.
- Planktonic Kit: Used for liquid samples
- Sessile Kit: Used for solid samples
Both kits contain all the consumable materials required to run the specified number of tests.

ATP Testing Sample Handling Tips
- When collecting the raw sample use a clean container and triple rinse
- Complete the field portion of the kit at the sample point to obtain the most accurate ATP/microbial count
-
- Handle coupons by the edges, it is important to not disturb the surface of the coupon
- Place coupon directly into the Reagent X tube with the extraction fluid or into the field container and add the Reagent X
- For coupons with high amounts of hydrocarbon present use one of the following options:
- Hang or slightly shake coupons to allow the hydrocarbon to drip off
- Lightly run the coupon between thumb and forefinger (with gloves on) (Caution: if sand or solids present this may scratch coupon surface)
- Blotting the surface of the coupon with clean paper towel may be an option (Caution: there can be free ATP on the paper towel)
- Set a standard for handling all coupons; this will improve trend data
- For coupons with scale, if scale analysis is required remove scale first:
- Sterilize a sharp instrument (wipe with an alcohol swab) and if possible only disturb one side of the coupon
- Notes and pictures of coupons, as they are removed from the system, can help to understand the data generated from the testing. Keep in mind that there are no set rules, but it is important to treat all samples the same.

- Depending on the sample you may be able to pick up a small amount with a clean, gloved hand and place directly into the tube
- If using a tool or spatula sterilize with an alcohol swab to prevent contamination
- When possible get an accurate mass or volume

LIFECHECK ATP TEST KITS WERE DESIGNED TO HANDLE OIL AND GAS WATERS, OFFERING A POWERFUL COMBINATION OF SPEED, VERSATILITY, PORTABILITY, AND ACCURACY FOR MICROBIAL TESTING.
LifeCheck ATP Test Kits were designed to handle nasty, commingled waters. The Kits offer an easy, fast and accurate microbial enumeration method valuable in routine monitoring and microbial management programs.
Other ATP technologies have been designed with ‘clean’ water in mind. Due to the presence of hydrocarbons and interferences within oil and gas fluids, these ATP technologies provide variable results. LifeCheck ATP takes into consideration interferences present, providing a wash/rinse step along with enzyme verifications to ensure the highest degree of accuracy.

ATP takes approximately 5-10 minutes to complete and can be conducted on-the-go (portable) or in a lab. For more information, watch our training videos or see our LifeCheck ATP Handbook.
- Drawing the sample into the supplied syringe and passing it through a filter to remove any debris and trap the cells on the filter
- A rinsing step to remove contaminants
- Passing the Reagent X through the filter to break open the cells, releasing the ATP for analysis
- The solution collected after passing Reagent X through the filter contains the ATP
- Mixing the resulting liquid with Reagent Z that contains an enzyme that uses this ATP to emit light
- Measure the amount of light (RLU’s) using the LifeCheck PhotonMaster
- An easy to use calculator tool then converts the RLU reading to a measure of microbial load (Microbial Equivalents)
