Virucidal gels became a scarce commodity before the COVID-19 coronavirus could cross the borders. Fortunately, according to the information provided by WHO, the antibacterial gel can be made by yourself with high-grade alcohol.

According to the recommendations of the Ministry of Development, developed in cooperation with the Chief Sanitary Inspector, the employer’s task is to “promote regular and thorough washing of hands by persons staying in public places: with soapy water or disinfecting hands with an alcohol-based agent (min. 60%).” Josef Prusa, the founder of Prusa Research, followed the guidelines and did it as always in his own, unconventional style…

The Prusa Research team adapted one production line for the production of antibacterial gel, thanks to which 1000 liters of fluid was created, which is a weapon in the fight against COVID-19. The gel was created for the health of employees – they will be able to use it both at work and at home.

The fluid was created on the basis of isopropyl alcohol (exactly the same which is used to clean 3D prints of excess unalloyed resin), hydrogen peroxide and glycerin. It is true that high-percentage alcohol (> 60%) alone is deadly to bacteria, but in order to prevent the alcohol from evaporating too quickly and increase its effectiveness, it is necessary to prepare an appropriate dilution. However, glycerin prevents excessive drying of the skin of the hands.

The liquid was distributed to dispensers with an original label, on which Josef Prusa is depicted as Mr. Prusa – a character inspired by Mr. Proper (or Mr. Clean), with the likeness of Procter & Gamble cleaners.

In the case of Prusa Research, a modern way of doing business and flexible production allows us to adapt to the most extreme situations.

Well done, Prusa Research!
