miraculix QTEST PHOTOMETER  

miraculix is the first to bring photometric analysis — a laboratory-grade technique for measuring the concentration of active compounds — into the field of drug checking.

In collaboration with IO Rodeo, experts in open-source scientific tools, we developed the QTest Photometer: an open source portable, user-friendly device that accurately quantifies the color reaction of your QTest.

Whether you're testing psilocybin in mushrooms, MDMA, or LSD, the concentration appears instantly on screen — no lab, no software, no calculations.

It solves one of the biggest challenges in drug checking: not just identifying what’s in a sample but knowing how much. By transforming a visual color shift into a precise numerical value, within minutes, it empowers safer, more informed decisions.

The QTest Photometer is ideal for analyzing batches, comparing sources, or ensuring consistency across multiple samples.

Now one of our best-selling tools, it’s used by individuals at home, by drug checking teams across Germany and Switzerland, and by university research projects.

Why Use a Photometer in Drug Testing?

As the market for substances becomes increasingly risky, with dangerous adulterants often present, simply knowing what is in a sample is not enough—you need to know how much. Misjudging the potency of a substance can lead to serious health consequences. That’s why miraculix pioneered the use of photometry in drug testing. Our QTest Photometer allows users to detect both the presence of a substance and its exact concentration.

Photometric analysis provides a scientifically validated approach to quantitative testing, offering a significant advantage over traditional reagent tests, which only give qualitative results (yes/no). This level of precision empowers users to make informed, safer decisions.

Refer to our Step-by-Step Guide to learn exactly how to get started with your QTest Photometer—from setup to your first measurement.

Pioneering Spectrophotometry in Drug Checking

miraculix: Pioneering Spectrophotometry in Drug Checking

miraculix has been a pioneer in bringing advanced scientific techniques into drug checking. Driven by the vision of our scientist, Dr. Felix Blei, we set out to combine the proven reliability of our QTests with the precision of spectrophotometry — not just to identify substances, but to measure their exact concentration. This integration marks a breakthrough in harm reduction: a method that is both accessible and scientifically rigorous.

To make this vision a reality, we partnered with IO Rodeo, specialists in open-source hardware for research applications. Together, we developed a photometer specifically designed for drug checking—accurate, portable, and simple enough for anyone to use. After multiple development stages, the result is a tool that empowers users with lab-grade precision, right at home.

Photometry vs. visual QTest reading

While our QTests with visual color chart readings are great for one-time or occasional checks, the QTest Photometer offers the next level of precision. It gives you exact numerical results, reducing interpretation errors and removing light-related variability.

The photometer is ideal for people who test frequently or in batches, and it's especially useful when tracking changes over time or comparing potencies. With the Psilocybin Bulk Kit, it also becomes more eco-friendly and cost-effective per test.

Whether you're starting out with harm reduction or already doing regular testing, this comparison helps you decide what best fits your needs.

The QTest Photometer is a small analytical device that measures how much of a specific substance (like MDMA, LSD, or psilocybin) is in your sample. 

The photometer provides results in just minutes after testing.

It measures the concentration of an active compound in your sample—like psilocybin, MDMA, or LSD—based on colorimetric reactions. Unlike traditional tests that only show presence (yes/no), this device tells you how much is present.

Yes! It runs on a rechargeable battery and is designed for use at home, at harm reduction booths, or even at festivals. It’s compact, durable, and travel-friendly.

No calculations are needed. The QTest Photometer automatically interprets the colorimetric reaction and displays the concentration of the active substance in your sample—no math, no charts, and no software required.

A blank is a cuvette filled with the detection solution but without any sample. It's used to calibrate the photometer and set a baseline before testing your actual sample. This step ensures that your results are accurate and not affected by light or impurities in the liquid. If you want to know more please refer to our Step-by-Step Guide.
