Embodiments of a present disclosure relate to a petri dish, and more particularly to, a petri dish with gradient scale.
A petri dish or a petri dish is a shallow transparent lidded dish that biologists use to hold growth medium in which cells can be cultured, originally, cells of bacteria, fungi and small mosses. Mostly in research and development laboratories of pharmaceutical industries, fermentation industries, medical or pathological laboratories, biotechnology and microbiology laboratories, or the like; plate assay techniques are used in day-to-day practice. In this assay strength of a compound is estimated from zone of inhibition or zone of exhibition or in case of biosurfactant, oil-displacement assay. In most of the approaches of using such assay or the petri dishes, a user must use a ruler or a scale to take measurements and note. In addition, taking bacterial count is a common practical in all above said fields, through some conventional approaches, differentiating the colonies and observing the growth is a tedious process and is not very accurate. Furthermore, in biosurfactant assay, as a test oil is layered on distilled water surface and a drop of biosurfactant to be tested is added, according to the strength of the biosurfactant oil is displaced. This is a quick response, and a bit more time taken in adjusting ruler scale leads to misinterpretation, also making the approach slower. These limitations make the system less reliable and less efficient. Furthermore, taking colony count from the Petri dish is one more practice, however, it becomes critical while counting hundreds of colonies from backside of the plate, in order to ease the process, a plate is usually divided into four quadrants manually. In addition, whenever a plate is filled up with about 20 ml of medium with approximation, some plates may get more, and some may get less medium. Observation of colony morphology is very basic requirement which makes the thing time consuming with unaided eyes. Also, collection of moisture in a lid poses a difficult task for a smooth handling of the Petri dish as well as in observations of results. Even sometimes this moisture interferes with results, thereby making the conventional approach less reliable and less efficient.
Hence, there is a need for an improved petri dish to address the aforementioned issue/s.
In accordance with one embodiment of the disclosure, a petri dish is provided. The petri dish includes a base plate configured to hold a material. The base plate includes a graduate scale with marking. The base plate also includes a plurality of sector lines arranged to divide the base plate into a plurality of sections.
