AquaSnap® Total and AquaSnap® Free Water ATP Tests
For water samples
Product No. AQ-100X (AquaSnap Total, 100 tests)
Product No. AQ-100FX (AquaSnap Free, 100 tests)
Introduction
Description and Intended Use
AquaSnap® water testing devices are self-contained ATP tests for use with
Hygiena® luminometers. Tests are used to monitor ATP levels in water as a
quality indicator in areas like clean-in-place (CIP) systems and rinse water
samples. They are also used for water treatment applications in healthcare and
monitoring biomass in cooling towers. AquaSnap Total measures both ATP
contained within living cells and particulate matter (microbial ATP) as well
as ATP dissolved in water (non-microbial or dead microbial ATP). AquaSnap Free
measures only dissolved ATP outside of living cells (non-microbial ATP). Used
together, AquaSnap Total and AquaSnap Free can be an effective quality
monitoring system. The difference between Total and Free test results
represents ATP from living organisms (also referred to as biomass).
Total ATP = Free ATP + Microbial ATP; therefore,
Microbial ATP = Total ATP – Free ATP

Important Tips and Notes Before Starting the Test
- Allow the AquaSnap device to equilibrate to room temperature (21 to 25 °C) before use.
- Turn on the luminometer. If the luminometer has been programmed with test locations, select the appropriate location before running the test.
- Use one of the following sampling recommendations when using both AquaSnap Total and Free:
o When possible, split the water sample into two aliquots. Dip each AquaSnap test (Total and Free) in a separate aliquot of the same water sample.
o If two aliquots of the water sample cannot be made and two devices must be dipped in the same sample container, first use AquaSnap Free followed by AquaSnap Total.
Test Procedure
-
Forcefully flick the device in a downward motion to shake the liquid extractant from the sample collection dipper to the bottom of the tube.
Note: this is important for accurate extraction of ATP and helps with sample collection consistency. -
Holding the tube firmly, twist and pull the top of the collection dipper out of the tube.
-
Submerge the collection dipper in the water sample for 1 – 2 seconds.
-
Lifting vertically, remove the collection dipper from the sample and reinsert into the tube.
-
Gently shake the device for 1 – 2 seconds to mix the water sample with the extractant at the bottom of the tube.
-
To activate the device, hold the tube firmly and use your thumb and forefinger to break the Snap-Valve by bending the bulb forward and backward. Squeeze the bulb twice to expel all the liquid into the tube.
-
Shake for 3 – 5 seconds to mix the sample. Once activated, the sample must be read in the luminometer within 15 seconds.
-
Holding the luminometer upright, insert the entire AquaSnap device into the Hygiena luminometer.
-
Refer to the instrument manual for operating instructions. In brief:
a. If using the EnSURE® Touch luminometer, close the lid and press “Run Test” to initiate the measurement. Results will be displayed in 10 seconds.
b. If using the EnSURE® or SystemSURE Plus® luminometer, close the lid and press “OK” to initiate the measurement. Results will be displayed in 15 seconds.
Additional Information
Interpretation of Results
Hygiena recommends setting RLU thresholds according to user’s test
application. Higher RLU results indicate higher contamination in the sample.
In clean or treated water samples, Free ATP results are similar to Total ATP
results. In some circumstances, when organic matter is present and where
microbial contamination is low, Total ATP results may appear lower than Free
ATP results; this is normal and is due to the presence of extractant in
AquaSnap Total. View the technical bulletin, Lower and Upper RLU Limits for
ATP Monitoring Programs, at
www.hygiena.com/documents or contact your
local sales representative or regional technical services team for guidance.
Calibration and Controls
It is advisable to run positive and negative controls according to Good
Laboratory Practice. Hygiena offers the following control: CalCheck LED
Calibration Verification Device (Product No. CAL).
