Definitions

  • the invention relates to a container for holding nutrient media, in particular petri dish, contact plate or sedimentation plate, for the cultivation of microorganisms, cell cultures, bacteria, etc.
  • Containers for receiving nutrient media are well known in practice. For example, reference is made to DE 10 2007 027 273 A1. From this document, a so-called contact plate or Abklatschplatte is known, namely a Petri dish, which is filled with solidified nutrient medium. To handle the Petri dish in the sense of a contact plate, the shell is filled so that the nutrient medium, regularly agar, protrudes at least slightly beyond the peripheral side wall of the shell. To clot, the container is gripped on the peripheral wall of the shell and the supernatant surface of the nutrient medium is pressed onto the surface to be "clipped.” Contaminants, especially bacteria, adhere to the surface of the solidified nutrient medium, providing an ideal breeding ground for bacterial cultures.
  • the shell After wiping off the contaminated surface of the nutrient medium is covered or the shell is closed with a lid which is at least slightly spaced from the surface of the nutrient medium, with the bacteria adhering there. Between the inner wall of the lid and the surface of the nutrient medium remains a sufficiently large space, so that in the prevailing atmosphere, the cell cultures can develop. There are aerobic and anaerobic embodiments of such contact plates known, as needed and objective with respect to the bacterial cultures. In other words, the lid can air or gas-tight or ventilated attach to the shell body.
  • the present invention is based on the object, a container of the generic type to design and further develop that eliminates the above problems, but at least are significantly reduced. Specifically, condensation in the area above the nutrient medium - before use - should be avoided.
  • the filling of the container should be possible with simple means in a very short time.
  • the handling both during filling and in the application should be as simple as possible.
  • the container for receiving nutrient media in particular petri dish, contact plate or sedimentation, for culturing microorganisms, bacteria, etc., comprises a base body with circumferential wall and a bottom plate with a base and peripheral wall.
  • the main body and the bottom plate form a shell.
  • For filling the shell with nutrient medium for storage and transport of the main body is inserted into the peripheral wall of the bottom plate, wherein the wall of the body at least slightly to the base of the bottom plate is spaced.
  • the base body can be inserted or inserted into the base plate, such that when pouring in the nutrient medium, it protrudes from the peripheral wall of the base body.
  • the nutrient medium is poured into the base body from the back and terminates with the inner wall of the bottom plate. After the pouring of the nutrient medium, any space between the main body and the bottom plate is filled, so that the previously available air space on the surface of the supernatant medium is eliminated. A condensation is therefore excluded there.
  • the exclusion of condensation is of particular importance in order to avoid soiling, especially smear infections. In particular, it is about contamination of user equipment.
  • the container according to the invention has the advantage that when pouring the nutrient medium no air bubbles on or on the contact surface arise because these, namely, if present, during filling and immediately afterwards in the nutrient medium rise up, namely from the contact surface (Abklatsch components ) remove. Since any bubbling does not present any problems insofar as the bubbles do not form on the surface used for culturing, the filling with nutrient medium can be accelerated once again. This is of special importance.
  • a closure is attached after filling the body with nutrient medium, so that the container is closed on the Abklatschseite by the bottom plate and on the Abklatschseite facing away from the filling through the closure.
  • the container is transported as a contact plate or Sedimentationsplatte and stored or provided for use.
  • the container according to the invention implies a very special method, namely a method for filling such a container, after which by the base body and the bottom plate formed shell is filled from the back with liquid nutrient medium, and wherein a distance of the peripheral wall of the base body relative to the base of the bottom plate ensures a supernatant of the nutrient medium on the circumferential wall of the body out. At the same time the usual air space between the surface of the nutrient medium and the inner wall of a lid is avoided. Condensation can therefore not take place there.
  • the container After the back filling of the container, namely from the contact surface of the culture medium side facing away, the container is closed on the back, including a special closure is used, which can also be equipped with sealing film.
  • the spacing of the wall of the main body from the base surface of the bottom plate is realized by a step formed near or at the base surface, preferably inwardly encircling step, groove or the like.
  • the base body according to the dimensions of the step, fillet or the like. Not a total plug in the wall of the bottom plate, but with a small distance to the base of the bottom plate. This distance ensures when pouring the nutrient medium required for Abklatschen supernatant of the nutrient medium.
  • the step, groove or the like can be performed circumferentially. It is also conceivable that this measure is provided for example at three or more locations, namely to define the distance of the circumferential wall of the base body relative to the base surface of the bottom plate.
  • the step, groove or the like may have a height in the range of 0.1 mm to 5 mm, so that in fact the nutrient medium protrudes sufficiently beyond the edge region of the main body.
  • the solidified nutrient medium is at least slightly exposed to the circumferential wall in accordance with the spacing of the wall of the base body to the bottom plate, resulting in the usability of the filled container as a contact plate.
  • the achieved It is necessary to bring the nutrient medium into contact with the surfaces to be tested or contaminated.
  • a contact plate is a "crowded" petri dish, namely a Petri dish filled with nutrient medium, in which the nutrient medium protrudes beyond the edge area of the dish.
  • the main body forming the shell has, on the side facing away from the contact surface, namely on the filling side, a closure in the sense of a removable cover.
  • This cover is attached after filling the body or the shell for closing the container.
  • This may be, for example, a film laid over the edge, in particular additionally glued thereto, or the like.
  • the cover is designed as a lid with circumferential wall, which encompasses the base body.

  • This space is necessary for the cultivation of microorganisms, because there is a certain airspace or a certain atmosphere for To be provided for transport and storage of the container with filled culture medium, before use, to be avoided.
  • the wall of the bottom plate is designed and dimensioned such that the bottom plate after removal of the cover instead of this on the wall of the shell, this cross-over, can be placed.
  • the cover and the bottom plate due to their specific design, can optionally be attached to both sides of the body, wherein for providing the contact plate with nutrient medium, the bottom plate sits directly on the contact surface of the nutrient medium, namely due to the special filling according to the foregoing ,

  • the basic body preferably comprises anchoring means extending through the interior of the basic body in a central or lower area. These anchoring means are surrounded during filling with nutrient medium and serve to hold the poured nutrient medium, on the one hand when lifting or removing the bottom plate and on the other hand in the process of Abklatschens.
  • the anchoring means favor the "holding" of the nutrient medium in the main body or in the shell formed by the main body.
  • the anchoring means may be struts or a lattice-like structure, so that unintentional slipping out of the nutrient medium from the main body is effective is avoided.
