QTest Photometer
The QTest Photometer is a portable and standalone device for the evaluation of our quantitative tests. It measures the color intensity and outputs the direct values for the measured alkaloids.
It displays directly how many milligrams of psilocybin are in your mushroom sample or how many micrograms of LSD are on your blotter, for example.
We have already measured all pure substances at the university and have shared all data and calibration lines publicly. Regardless of this, it is a proper open-source photometer and can measure different wavelengths and be useful for a lot of other experiments besides QTests.
Introducing the QTest Photometer: Precision in Drug Analysis
The QTest Photometer by Miraculix in cooperation with IO rodeo, revolutionizes drug checking by combining cutting-edge spectrophotometry technology with user-friendly design. This portable device allows individuals to accurately measure the concentration of active compounds, such as MDMA and psilocybin, using minimal sample sizes from the comfort of home or in harm reduction settings. With its quick results, precise measurements, and ease of use, the QTest Photometer empowers users to make safer, informed decisions about their substance use, ultimately enhancing harm reduction efforts in an increasingly risky market.
If you would like to learn more about how the idea for the QTest Photometer originated, how Miraculix pioneered the use of this technique in drug checking, and discover key features, check out our blog. We also provide a step-by-step guide on how to use the QTest Photometer, along with insights into the advantages of photometry over traditional qualitative reagents.

Frequently asked questions about the QTest Photometer
These are the answers to frequently asked questions so far:
A "blank" is an initial measurement using an unused detection solution. Its purpose is to eliminate any interference from the detection solution, ensuring that the results reflect only the substance being measured. It is essential to perform this blank measurement before testing your samples for accurate results.
Before performing the detection solution step, take 800 µl from the unused detection solution and add it to a cuvette. Use this cuvette to blank the photometer. After blanking, return the 800 µl of detection solution back to the original container. Complete the Qtest procedure as usual, follow the instructions in the manual for this.. After finishing, take 800 µl of the colored detection solution and measure your sample. Important!: It is crucial that you do not change any settings between performing the blank and measuring your sample. If the settings are changed, you will need to blank the photometer again.
The cuvette has a face marked with a triangle pointing downwards. This side should be positioned parallel to the photometer screen, with the triangle pointing toward you. This ensures proper orientation for accurate measurement.
Yes, always use a clean cuvette to measure your sample. After performing the blank, carefully pipette at least 800 µl of the colored detection solution into a new, empty cuvette to avoid any contamination or interference from previous samples.
No, once you have performed the initial blank, you can measure several samples consecutively without needing to perform another blank, as long as the samples are from the same QTest. Be sure to use the correct detection solution for each QTest.
If you switch from one QTest to another (e.g., from the MDMA-QTest to the LSD-QTest), remember that the blanks are not interchangeable. You will need to perform a new blank using an unused detection solution specific to the QTest you are about to conduct.
The LSD-QTest has two protocols: one for measuring the amount of LSD on a blotter and another for measuring a drop of liquid LSD. Make sure to follow the correct protocol depending on the form of LSD you are testing for accurate results.
