Abrégé

A Petri dish includes a receptacle and a matching lid, which both have a shape of revolution and are each delimited by a bottom wall and at least one peripheral rim. This also includes fingers and complementary locking elements. The receptacle and the lid, when rotated relative to each other, are able to occupy three or four different positions, including at least a “first position” and an “intermediate position”. This dish is distinguished by the fact that the locking elements carry at least one blocking member which blocks the fingers in the “intermediate position” and which opposes the return to the “first position”.

Petri dish (1), which consists of two components, namely a receptacle (2) and a complementary lid (3), which both have an axisymmetric shape and which are each delimited by a bottom wall (20; 30) and at least one peripheral wall (21; 31), characterized in that said receptacle (2) and lid (3) bear complementary locking means (5; 4) arranged such that, when a stack is formed by superposing at least two dishes, the locking means borne by a first component (2; 3) of a first dish can engage with the locking means of the second component (3; 2) of the second dish, thus making them rigidly connected to one another. These locking means (5; 4) are capable of engaging by relative rotational movement of one dish (B1) with respect to the other (B2). They are borne by the peripheral walls (21; 31) and consist of protrusions (5; 4).

Abrégé

The present invention relates to a Petri dish (1) consisting of a receptacle (2) and of a matching lid (3), which both have a shape of revolution and are each delimited by a bottom wall (20; 30) and at least one peripheral rim (21; 22; 31). It comprises fingers (4) and complementary locking elements (V). The receptacle and the lid, when rotated relative to each other, are able to occupy three or four different positions, including at least a "first position" and an "intermediate position". This dish is distinguished by the fact that said locking elements (V) carry at least one blocking means (53) which blocks the fingers (4) in the "intermediate position" and which opposes the return to the "first position", while permitting the move to the following position.

The invention relates to a device for dispensing a prescribed material into a Petri dish, each Petri dish (P) comprising a removable lid capable of being arranged on a bottom (F) that is not as broad as the latter, comprising a means for bringing the Petri dish to a material-dispensing station (40). According to the invention, the device comprises a piston (32b) comprising a plate (320b) for supporting the bottom (F) at the material-dispensing station and means for rotating the plate (320b) on itself relative to the dispensing head (6), arranged so as to rotate the bottom (F) relative to dispensing head (6) in the position for dispensing the material into the bottom, in which the material outlet tip (61) is arranged relative to plate (320b) in order to dispense the material into the rotated bottom (F).

Abrégé

The present invention relates to an assembly formed from a planar rigid filtration membrane and generally flat plate (5) for accommodating and supporting this membrane (3), especially for the purpose of activating and/or revealing immobilized contaminants on said membrane, this support plate (5) having retention and immobilization means capable of cooperating with the periphery of the membrane (3), characterized in that said means comprise at least one non-deformable member (6) that projects from the general plane of said plate and which includes at least one stop tab (60), generally perpendicular to said plane (P), which is extended by a retaining appendage generally parallel to said plane, so that the engagement of said membrane (3) with said member (6) can take place only through a first movement (k) of the membrane substantially parallel to the plane (P) of the support followed by a second movement substantially perpendicular to said plane (P).

The invention relates to a device for dispensing a prescribed product in a Petri dish, said device comprising pistons (32a, 32b), a transfer member (31) with lid-bearing openings and a dish bottom, and product-dispensing means (6). According to the invention, the transfer member (31) is a shuttle (31) capable of translation relative to the base (2) according to a direct reciprocating movement of the bearing openings between either of first and second stop positions, the dispensing means (6) being arranged so as to dispense the product above the inner opening and under the upper opening at the bottom of the dish when said openings are in a position selected from the first and second stop positions.

The invention relates to a device for diluting a sample, comprising an end-piece (9) for dispensing a liquid diluent, means, having an upright (12) extending upwards from the base (2), for supporting and moving the end-piece (9) relative to the container support (6) between a first position in which the outlet (93, 94) of the end-piece (9) lies above the opening of the container, to allow the diluent to be fed into the container, and a second position in which the outlet (93, 94) is further away from the container. According to the invention, the second position of the outlet (93, 94) is to the side of the first, the upright (12) is fixed to the base (2), and the upright (12) has a cover (13) at the upper end thereof for supporting the end-piece (9), the cover (13) being rotatable on the upright (12) between said positions, a rotary drive motor for rotating the cover (13) between said positions being housed on the inside of the cover (13) and/or of the upright (12).
