Abstract:
A culture dish for growing cultures such as tissue cells, bacteria and the like. The culture dish includes a handle extending therefrom that can be easily grasped by a user when lifting or handling the culture dish. The culture dish can also include a lid that can be placed on a base of the dish to prevent contamination of the cultures and to control evaporation or liquid from the dish. The handle can extend from the base, the lid or both. If the handles are provided on both the base and the lid, they can be configured differently so that a user can readily distinguish between them.
Abstract:
A microplate (10) and a method for manufacturing microplates. The microplate (10) is designed to reduce optical cross-talk during the assaying of samples. The microplate (10) comprises a plurality of wells (12) having light impermeable sidewalls (16), a layer of light permeable material forming a bottom (20) of the wells (12), and ribs (22) of light impermeable material extending through the layer of light permeable material. The method includes steps of inserting a plate of light permeable material into a mold cavity that includes sections shaped to form the sidewalls of the plurality of wells, injecting molten light impermeable material into the mold cavity, and cooling the light impermeable material to form the microplate with the light impermeable material forming the sidewalls of each of the plurality of wells and the plate of light permeable material forming the bottom wall of each of the plurality of wells.
Abstract:
A filter cartridge that includes a track etched membrane sealed therein in a leak-free manner, and a method for making the cartridge. The filter cartridge has a bubble point that is at least 50 % of the bubble point of the track etched membrane. In one embodiment, the method includes disposing the track etched membrane below a heat source and orienting the membrane so that it melts back on itself, and then allowing the membrane to cool to form a leak-free seal.
Abstract:
A device and method for growing tissue or cells on both sides of a membrane includes a cylindrical body which may be stood on either end in a culture well. A frame is slidably mounted in the body and carries a membrane, on both sides of which tissue or cells are to be grown. A tissue or cell sample is placed on the upper surface of the membrane and media is supplied to the well on the outside of the body. Passages at the bottom of the body allow the media to flow to the membrane and nurture the sample to cause its growth. When the first monolayer is grown, the body is inverted and the frame is pushed to the other end of the body, preferably by a jig supplied for that purpose. A second cell sample is deposited on the other side of the membrane, again on top of the membrane and it is nurtured by media supplied primarily from the reservoir on top and secondarily through the membrane.
