Microbiology

Microbiology is a science which observes the evolution of microscopic organisms having a size smaller than 1 mm. Several themes divide this study: biology, biochemistry, ecology and their actions in our environment.

 

Microorganisms present around us are diversified. We can classify them according to 3 living world scopes: bacteria, arches and eukaryote. We distinguish 3 categories thanks to their shape, their size and their way of life that microorganisms adopt.

 

Thanks to our high-tech equipment, the microbiology range is reliable and our laboratory disposable quality is in accordance with this activity.

Square Petri Plates 120 mm x 120 mm


Square Petri dishes are used for screening operations (Filtration). Indeed they can have several uses: in the analysis of agar diffusion and in bacteriological work.

 

The design is specific for automation and colonies prinking out and the bank clone storage. The square Petri Plate 120 x 120 mm has a large surface which is a main advantage for cultivation’s growth.

Petri Dish diameter 55 mm


Petri plates diameter 55 mm are especially used in water microbiology. Those which have a high shape are ideal for liquid cultivations such as mycoplasma culture. In water microbiology, a filtration of the sample can be made through a membrane.

 

Thanks to narrowed stitches it plays a sieve role. On the membrane we can see bacteria then they are cultivated in a Petri dish. The all is thus incubated in optimum conditions for bacteria proliferation. The use of a Petri plate diameter 55 mm avoids the sling scattering on a too important surface.

Round Contact Petri Dish


Thanks to its rounded bottom contact Petri plates, a convex meniscus sets up and spreads uniformly the agar and the contact with this and the surface to analyze is optimum. Moreover rounded bottom permits saving 19% of the agar without reducing the quality of the analysis.


Contact dishes are used on the occasion of environment controls. Microbiological contamination controls can be made on many surfaces: skin, kitchens, lab benches and operating rooms.


Thanks to numbered shelves within those plates, the germ colony-counting is easier. Germs presents stick to the agar, once incubated the colony counting is brought back to cm² of the analysis surface.


Petri dishes having a flat bottom allows as for getting a better plate’s stability.

Petri Plates diameter 90 mm


Our standard Petri dish range is composed of 2 main categories some which have a 14.2 mm’s height and correspond to the Latin market.

 

On the other hand Petri plates which have a 16.2 mm’s height fit to the Anglo-Saxon market. Standards Petri dishes are used for micro-organism cultivation.

 

Petri plates with compartments outline 2 major advantages: you can save space in the incubator and cultivation mediums.

Inoculating loops and spreaders


Inoculating loops


Inoculating loops from our product range are color coded in order to find them rapidly during laboratory operations.

 

Inoculating loops help to sample colonies in different mediums. Inoculating loops get a base entirely rounded with a soft edge without imperfections.

 

All these cautions don’t damage the agar.

L form Spreader


This tool help to spread uniformly samples on the agar without touching the Petri dish wall. The end is put up avoiding damage the culture medium surface.

Petri dish diameter 140 mm


This Petri plate with a specific size serves making antibiogram. This technique was conceived in order to test the sensitiveness of a bacteriological stem towards several antibiotics.

 

Several antibiotics are present in the Petri dish with the bacteria culture then an observation of the development is realized. Several methods exist to make the analysis. Indeed it is possible to deposit patches containing antibiotics in the Petri plate and put in touch with bacteria.

 

Another technique consists to dig a hole in the agar and deposit directly antibiotics inside. Three interpretations could be made according to the circle diameter which surrounds the antibiotic’s disk: sensitive bacteria, intermediate or resistant.

 

The Petri dish diameter 140 mm is useful for comparatives analysis because all bacteria are evolving in the same culture medium and thanks to its wide area, tests places are correctly distinct avoiding by the way cross contamination with the bordering medium so results are more convincing.
