FAQ’s

We solve all your questions about our chemical submission prevention technology.

How does the wristband work?

It’s very simple—it works like a miniature chemical laboratory. The wristband contains chemical sensors on its surface. You only need to place a drop of your drink on the sensor area using your finger (dip your finger into your drink and touch the sensor directly; you can then dry your finger with a tissue if you wish).
• If the drink is safe: The color remains the same—nothing happens.
• If a drug is detected: An immediate chemical reaction occurs, showing a visible color change. The GHB detector darkens (from orange to dark green or bluish), and the amine detector changes from yellow to red, alerting you to danger instantly.

Is it safe to use the wristband?

Yes, absolutely. The wristband has been designed as a product for external use. The chemical reagents are fixed within the material and do not come into harmful contact with your skin, complying with REACH chemical safety regulations. In addition, it is a passive device: it has no batteries, no chips, and no electronic emissions, so there is no risk of electric shock or overheating. Its sole purpose is to analyze the liquid, not the user.

Where can I get it?

At Celentis, we adapt to your protection needs, no matter the quantity.
If you’re an individual or want to look after the safety of your group of friends, you can purchase our wristbands in small quantities directly through our website and, very soon, in selected pharmacies.
On the other hand, if you represent an institution, festival, or nightlife venue, we offer bulk purchasing for events and public awareness campaigns — get in touch with us. In fact, thanks to these institutional agreements, it’s very likely that our technology is already being offered at access points in your favorite venues.

How much does it cost?

We have optimized our manufacturing process through industrial printing techniques to offer an accessible and cost-effective product. This scalability allows us to adjust pricing: the higher the purchase volume, the lower the unit cost.
While the final price may vary depending on the distribution channel or whether the wristband is included directly with an event ticket, our non-negotiable goal is to ensure that your safety is always affordable—costing less than a standard drink at any nightlife venue.

Does it work in all drinks?

Our technology has been scientifically validated to work across a wide range of complex matrices. This includes alcoholic beverages (mixed drinks, beer, wine, spirits) as well as soft drinks or juices typically consumed in leisure settings. The sensors are calibrated to avoid false positives caused by the alcohol or sugar naturally present in the drink.

What drugs does it detect?

The current version of the wristband features a dual detection system for the most common substances involved in drink spiking:
• GHB (Liquid ecstasy): Detects the presence of gamma-hydroxybutyric acid.
• Amines: A broad group of drugs that include the amine functional group in their chemical structure, comprising more than 15 stimulants and other psychoactive substances such as ketamine, methamphetamines, MDMA, scopolamine, or burundanga.

Is the wristband reusable?

Yes, it is reusable. Unlike single-use test strips, our wristband allows multiple tests throughout the night. You can check your drink, a friend’s drink, or verify a new glass later—or even the same one several times. As long as there are unused test areas or the reactive sensor has not been excessively diluted, the wristband remains functional.

How long does storage last without losing the properties?

Thanks to stability studies carried out, the wristband maintains its effectiveness for several months when kept in its original packaging, protected from direct light and excessive humidity before use. Once opened and worn on the wrist, it is designed to ensure maximum reliability throughout the entire duration of the event.

Testimonials

Real stories of people who have found security in our bracelet

★★★★★

“Never let your drink out of sight when you’re out partying. Someone might contaminate it with liquid ecstasy (GHB).”

Guardia Civil recommendation

★★★★★

“I’ve sometimes thought that someone might have put something in my drink — you feel very drunk very quickly, like it doesn’t match the amount you’ve had. I wish I’d had something like this to check it.”

Workshop Participant

★★★★★

“It’s very important to raise awareness about a reality like this. I have friends this has happened to, and thanks to us staying alert it didn’t escalate, but the feeling of confusion is overwhelming. Being able to test immediately allows you, for example, to go to the emergency room with more information.”
