The widely us of Perti dish
Petri dish is a lab ware for microorganisms
or cell culture, by a plane of the bottom of the disc and a cover, usually made
of glass or plastic, commonly used in plant materials, microbial cultivation,
animal cells adherent and vaccination, marking, separation of bacteria in the
laboratory and operation, etc.
As a cell culture vessel, petri dishes are
widely used in biological fields such as bacteria and cell culture.The main
structure of a typical dish consists of a dish body and a plate lid, which is
formed by a single bottom wall and a side wall.Existing culture dishes are
generally available for different culture objects.General design, often at the
expense of individual needs at the expense of, when this kind of general dish
is applied to some special training objects, cannot fully meet the demand for
personalized, shows a general lack of petri dishes.
At present, used in petri dishes all
existence of bacteria culture and installed at the bottom of the precarious
situation, easy to make the cover of loose, for example, when take put only
take cover, can make the bottom of the drop, cultures, affect the normal use.On
the other hand, the existing petri dish also has the disadvantage of air
permeability.
The culture dishes are basically divided
into two categories, mainly plastic and glass, which can be used for plant
materials, microbial culture and the wall culture of animal cells.Plastic may
be polyethylene material, which has a one-time and multiple use, suitable for
laboratory inoculation, marking and separation of bacteria, which can be used
for the cultivation of plant materials.
