A 61% lighter cell culture dish to reduce plastic waste

Cell culture is a ubiquitous and flexible research method. However, it heavily relies on plastic consumables generating millions of tonnes of plastic waste yearly. Plastic waste is a major and growing global concern. Here we describe a new cell culture dish that offers a culture area equivalent to three petri dishes but that is on average 61% lighter and occupies 67% less volume. Our dish is composed of a lid and three thin containers surrounded by a light outer shell. Cell culture can be performed in each of the containers sequentially. The outer shell provides the appropriate structure for the manipulation of the dish as a whole. The prototype was tested by sequentially growing cells in each of its containers. As a control, sequential cultures in groups of 3 petri dishes were performed. No statistical differences were found between the prototype and the control in terms of cell number, cell viability or cell distribution.
