The test principle of the MICRONAUT system for antimicrobial susceptibility testing (AST) is based on phenotypic detection of resistance as expressed by microbial growth in presence of antibiotic compounds. This micro dilution procedure is a standardized method and a worldwide accepted reference system for determination of the minimal inhibitory concentration (MIC).
For all MICRONAUT AST systems the various antibiotics are placed with or without broth in a dehydrated form into the wells of the microtitration plates and are dissolved by adding bacterial suspensions. After 6 hours (rapid AST) or 18-24 hours of incubation at 35-37°C the AST plate is measured in the photometer and the test is evaluated with the MICRONAUT software or read visually.
Choose your preferred standard like EUCAST or CLSI and compose your own customised antibiogram from more than 200 antibiotics. Otherwise you can select from a wide variety of standard layouts. Take your choice, whether it's breakpoint procedure, MIC testing or a combination of both.
The susceptibility testing with MICRONAUT-SB plates is based on the rehydration of antibiotics and broth by adding a bacterial suspension. After incubation of 6 hours (rapid AST) or 18-24 hours at 35-37°C the plates are read photometrically with the Skan device and the results are evaluated with MICRONAUT software. The plates can also be read and interpreted visually.
Because of a special vacuum drying process the plates are stable up to 24 months if stored at a room temperature of 15-25°C.
Any customer defined antibiotic configuration (MIC or break point) can be offered. Depending on the antibiotics and concentration ranges selected (breakpoint or MIC) 1, 2 or 4 isolates may be tested on a single MICRONAUT-SB plate. In addition customers have the choice to select between a diversity of standard AST panels.

The susceptibility testing with MICRONAUT-S plates is based on the rehydration of antibiotics by adding a standardized bacteria suspension. After incubation of 18-24 hours at 35-37°C the result is read photometrically with the Skan device and evaluated with the MICRONAUT Software or read visually and interpreted.
Because of a special vacuum drying process the plates can be stored at usual room temperature of 15-25°C. The MICRONAUT-S test plates have a shelf life of 24 months.

The susceptibility testing is based on the rehydration of antimycotics by adding a standardized yeast suspension. After incubation of 24-48 hours at 35-37ºC the plates are ready to be measured photometrically or be interpreted visually. Because of a special vacuum drying process the plates can be stored at a room temperature of 15-25°C. MICRONAUT test plates have a shelf life of 24 months at date of production.
