More bang for your buck.

Hygiena's advanced device design and liquid-stable chemistry offer greater sensitivity than other test devices, enabling you to detect even lower levels of ATP. 

Charm Hygiena Sensitivity


Realistic results.

Our patented device design ensures superior sample recovery and accurate ATP measurements. Why is this important? Inferior sample recovery means the sample will most likely be lost or diluted in the activation and mixing process, leading users to believe a surface is cleaner than it truly is.

Compare with a Side by Side Comparison Kit.

Running an objective side by side comparison is critical to evaluating a new system. To make this process easier for you, Hygiena provides a simple kit with all the materials to compare two systems. Side by Side Comparison Kits includes 3 vials of liquid ATP at 3 different levels (20, 200, and 2,000 femtomoles), a 10 µL pipette, 50 pipette tips, and detailed instructions for running the side by side comparison. Order a kit now!

ATP Side by Side Comparison Kit


RLU conversions, simplified.

No ATP systems measure on the same scale. Though Hygiena and Charm systems are measuring the same thing, (ATP), they quantify ATP on different scales. Imagine the two sides of a ruler - one side is in inches, one side is in centimeters, but both measure the same length. The same concept applies when comparing relative light units (RLUs) on two different systems. 

Ruler Charm 01 01

All ATP systems measure femtomoles of ATP (1x10-15 moles). Hygiena keeps it simple: 1 femtomole of ATP equals 1 RLU. Use the conversion tool below to convert RLU values among various system configurations.


*Conversion is approximate due to natural sample variation in test-to-test results and user variability. Approximation is based on years of experience successfully converting Charm users to Hygiena systems.
