Cleardrink™ is the first in history handheld, pocket-sized, single-use device for instant detection of methanol in alcoholic drinks.

Besides methanol, Cleardrink™ is designed to detect ethylene glycol and the rape drug GHB (γ-aminobutyric acid) as well.

The core of Cleardrink™ is a system of two interconnected vials, reactor and detector. Device provides permanent color result in seconds after the injection of a small sample of the drink.

Cleardrink™ is a patented test in Greece (Patent GR1009603B) which utilizes a unique, innovative technology of advanced oxidation and instantly converts the harmful substances to detectable gas, while non harmful substances are kept in the liquid phase.

Essentially, Cleardrink™ is an inexpensive technology ready to enter the market for the first time in human history as a useful tool in the pocket of the consumers and the law enforcement authorities.

Cleardrink™ has been tested in real conditions for repeatability and accuracy. Repeatability of its innovative analytical method is 100%, limit of detection is >0,3% in terms of methanol content.

Currently, Cleardrink™ is under final prototype development. Funding or investment is being seeked to enter the market soon.


Cleardrink™ has master benefits:

1. Consumers have a tool to check the drink beforehand and protect their health.

2. States with the rule of law have a unique tool to tackle tax evasion networks and illegal activities

3. Brand holders like Diageo and Pernod Ricard will raise their profits, when illicit drinks sold under their labels will be confiscated by the law enforcement authorities.

4. Cost per use for producing a unit is plastic shell plus 0,05$!


Methanol in drinks remains a global unsolved problem!

According to data by the MSF, more than 13.000 people have died during the last decades from the consumption of illicit alcoholic beverages that contained methanol.

Moreover, the World Health Organization had issued a directive in 2014, alerting the world for methanol in drinks and encouraging countries to implement preventive measures on the final parties of the supply chain. Here comes Cleardrink to protect the consumer before drinking.
