esi laboratory tests
The antimicrobial efficacy of esi has been tested and certified by the following laboratories:
esi test on coronavirus
Evaluation of the remote action of esi technology against the CORONAVIRUS HCoV-OC43 on a plastic surface.
The virus used: human coronavirus HCov-OC43 which has an extremely high homology of structure with the virus responsible for CoViD-19, HCoVSARS-2, from both a phylogenetic and molecular point of view.
Deposit of a 100μl aliquot of HCoV-OC43 viral suspension, on a surface of 2.5×2 cm of a plastic plate.
Two A + B emitters were used in the 2,280 cm3 experimental chamber:
A = code 480C
B = code 480A
at 15 seconds there was a reduction of> 82%
at 2 hours there was a reduction> 99%
test results of esi against bacterial
esi has been tested extensively to verify its action on bacterial loads. Important laboratories, research institutes and universities have conducted tests to verify the antibacterial action of esi in different conditions. Some of the most important experiments are those shown in the table opposite, where dangerous bacteria were tested. All bacterial loads were reduced to zero after exposure to esi.
Escheria Coli, highly contagious and dangerous, is known as “nightmare bacteria” because it is resistant to all known antibiotics and causes death in 50% of cases. Exposure to esi for 24 hours eliminated any bacteria, as shown in the petri dishes opposite.
Lo Saphylococcus Aureus, which belongs to the same class as Covid-19, Class 2 according to Legislative Decree 81/08, is very dangerous for humans. Exposure to esi for 24 hours eliminated any bacteria, as shown in the petri dishes opposite.
Candida, Saprophytic Fungus, a habitual commensal of the skin and mucous membranes, can cause serious health problems. Exposure to esi for 24 hours eliminated any microbial presence, as shown in the petri dishes opposite.
The methodologies used in the laboratory tests:
ISO 22196:2011 – JIS Z 2801:2010, ISO 18593:2004, UNI ISO 4833,
UNI 10802, PT048 rev00 2002, IL042 rev01 2005
The description of the laboratory methodology used, can be consulted on our website in the Laboratory Tests section.
test on 88 m² office with esi
An open space office of 88 m² with 14 workstations equipped with windows, air conditioners, desks and other technical furnishings, used by 14 people continuously over 8 hours with visitors during working hours, was subjected to comparative testing for cleanliness before and after the installation of the esi system.
T0: Detection carried out before installation esi. A test carried out on the surfaces of the desk top, PC keyboard, mouse, flooring, walls, window panes and door handle, revealed an average bacterial load on all surfaces of 610 CFU/cm2.
T1: After the T0 detection, the office was equipped with an esi system consisting of: Mouse Pads, esi-Monitor, esi PC Keyboard, Remote Control Door, Door Handles, and EMQ48 environmental emitters. After 12 hours, a second test was performed to detect the reduction of the bacterial load, with a detected value of 0 CFU / cm2.
The work environment tested with the use of esi technology confirmed the complete absence of bacterial loads even in the condition of normal use of the office by employees and guests.
test on 16 m² office with esi
An office with a workplace equipped with a window, air conditioner, desk and other technical furniture, used by a person continuously in the 8 hours that normally receives visitors, was subjected to comparative tests before and after the installation of the esi system.
T0: Detection carried out before installation esi. A test carried out on the surfaces of the desk top, PC keyboard, mouse, flooring, walls, window panes and door handle, revealed an average bacterial load on all surfaces of 540 CFU / cm2.
T1: After detection, the office was equipped with a system consisting of: Mouse Pad, esi-Monitor, esi PC Keyboard, Remote Control Door, Door Handle, EMQ48 environmental emitters. After 12 hours, a second test was performed to detect the reduction of the bacterial load, with a detected value of 0 CFU / cm2.
Considerations: The work environment tested with the use of esi technology confirmed the complete absence of bacterial loads even in the condition of normal use of the office by the employee and guests.
test on bathroom with esi
A men’s company bathroom of 2 m² was tested. At Time 0 an invasive test of bacteria inoculation was carried out, on the bathroom wich has a normal average of bacterial loads between 500 and 1000 CFU / cm2.
A bacterial load of Saphylococcus aureus, which belongs to the same class as Covid-19 (Class 2 according to Legislative Decree 81/08) with a deactivated bacterial strain was inoculated into the bathroom. The portion of the wall involved in the test was 10 x 10 cm located 130 cm from the esi nearest emitter.
The environmental esi emitter PR01 + esi WC pushbutton + esi WC KIT had been previously installed in the room.
12 hours after the inoculation of the bacterial load, a second test (Time 1) was performed to measure the residual bacterial load, and a value of 0 UFC/cm2 was detected.
esi eliminated all bacteria in the environment even in the presence of an extremely high starting value.
test on handle with esi
Every handle poses a potential threat to the health of people who can contract viruses, bacteria and fungi from surface contact.
esi technology has been applied to develop handles that are now in the Razeto and Casareto collection. In addition to design and functionality, the esi handles offer the added insurance of anti-covid, antibacterial and antifungal action.
A laboratory test conducted on a handle made with esi certified that after prolonged contact of 15 seconds with a hand contaminated by bacteria, the handle remained sterile at 0 CFU / cmq.
Furthermore, the same test performed on the person’s hand, after contact with the handle, found a 10% reduction in the bacterial load present on the hand.
The esi handles are perpetually free of microbial loads. Placed in all spaces with a high number of people, they guarantee the impossibility of contagion from the “touch of the handle”.
test on carpets
Wherever carpeting is used as flooring, it poses a threat to the health of the people inhabiting the space.
Various tests have found very high microbial loads even in normal conditions of cleaning and maintenance. Values of 3,000 CFU/cm2 were found in hotel rooms or yacht cabins; the World Health Organization considers a value of 50 UFC / cm2 “normal”. Therefore, these carpets were found to be 30 times dirtier.
Installed in the carpet substrate, esi acts through the humidity in the air. The ions emitted pass through the weft of the carpet weave, carrying out a 24/7 disinfection while neutralizing the bad odors characteristic of dirty carpets. In yachts, where carpeted floors are often used by barefoot guests, the values of “microbial dirt” found were considerably higher. The same is true in cars, particularly those used to transport pets.
esi guarentees a constant “microbial cleaning” through the continuous emission of silver (Ag+) and other metal ions.
The carpet test after 6 hours of being exposed to esi brought the bacterial load from 3.000 CFU/cm2 to 0 CFU/cm2.
test on armchairs and
sofas with esi
Sofas, armchairs and seats are normally contaminated by high microbial loads due to continuous contact with people. Fabric covers, compared to leather or similar coverings, have higher “microbial dirt” values due to the thickness of the upholstery and padding that makes thorough cleaning difficult. For this reason the various tests carried out during the sessions have found very high microbial loads even in conditions of normal cleaning and maintenance.
In some hotels and boats tested, values of 1,900 CFU / cmq were found; while 50 CFU / cmq is the value considered “normal” by the World Health Organization. The use of seating in yachts implies regular contact with the human skin of the guests and was found in various tests to have values of “microbial dirt” 1.52 times higher than the values typically found in seating for domestic use. This was found to be true for all the seating of “common areas” in any work environment.
esi installed in the lower part of the seats or within the structure allow constant disinfectation of the furniture as well as the surrounding environment.
Test: Starting value of a fabric armchair on a yacht: 1900 CFU / cmq
After 6 hours esi brought the bacterial load from 1900 CFU / cmq to 0 CFU / cmq.
Multipurpose esi Trunk
The trunk was designed for daily use in RIVA boats, to contain wetsuits, towels, shoes, accessories and other objects following their use.
Soiled sports clothes were subjected to laboratory tests to detect the bacterial load. Values of 2,500 CFU/cm2 were found.
The same clothes, placed in the trunk, were tested again after 3 hours and a charge of 0 CFU/cm2 was found. esi eliminated any form of bacteria previously present.
