PROBLEM TO BE SOLVED: To provide a user-friendly petri dish. SOLUTION: A cell culture dish comprises a dish having a bottom wall and a circumferential side wall rising upward from the bottom wall, a lid which sits sealingly on the side wall in an aeration position, and a means for keeping the lid on the dish above a sealing position in the aeration position in which an aeration gap is found between the side wall and the lid, and is configured to close these means by pressing the lid and the dish together to move the lid from the aeration position to the sealing position.

Abstract:
PROBLEM TO BE SOLVED: To provide a culture flask that makes it easier for a serological pipette, scraper, cannula or another elongated device to access the growth surface on the bottom wall.SOLUTION: A culture flask comprises: a culture chamber in a flask body 14 comprising an even bottom wall 3 with a growth surface 12 on the top side, an even cover wall 4 at a section from the bottom wall, and side walls 5,6, and 10 that bridge the distance between the margins of the bottom wall and the cover wall; an opening 13 that is in adjacent regions of the side wall and the even cover wall at a distance from the bottom wall; and a hollow cylindrical flask neck that is connected to the margin of the opening and is aligned at a sharp angle to the growth surface so that a serological pipette, a scraper, a cannula or another elongated device for adding or removing material can be placed specifically on the rear corners of the growth surface from the outside through the flask neck.
Abstract:
PROBLEM TO BE SOLVED: To provide a device which simplifies the transport of containers and working with containers while decreasing manufacturing expenses and the amount of waste.SOLUTION: A transport unit includes: two parallel retaining plates 2 which each include a configuration of retaining means 11.1 of lidded containers 3.1; and the lidded containers 3.1 which each have a tubular container and a closure element 7.1 projecting radially outward at the top of the container. The lidded containers 3.1 of one group 14.1 are held parallel to each other by the retaining means 11.1 of one of the retaining plates 2, and lidded containers of another group 14.2 are held parallel to each other by retaining means 11.2 of the other of the retaining plates 2. The lidded containers 3.1 of the one group 14.1 are aligned opposite to the lidded containers of the other group 14.2, and the lidded containers of both groups are disposed so as to be nested within each other.
Abstract:
PROBLEM TO BE SOLVED: To provide a pipette tip supplier reducing pollution risk of pipette tips, allowing reduction of package waste, and allowing easy charge, and to propose use of a replenishment pack allowing easy replenishment of the pipette tips.SOLUTION: This pipette tip supplier includes: the replenishment pack 2 having a porous plate 4 having a plurality of holes 11, the pipette tips 7 inserted in the holes 11, a container 5 covering the pipette tips 7 in a bottom part and having rigidity of 300 N/mm at the maximum, and a cover 6 covering the pipette tips 7 from a top part; and a holder 3 having a receiver for inserting the replenishment pack 2. A support means 19 supporting the replenishment pack 2 when the replenishment pack 2 is inserted in the receiver exists between the replenishment pack 2 and the holder 3.
