Microfluidic device features such as channels, valves, chambers, can be at least partially contained, embedded, or formed by or within one or more layers or levels of an elastomeric block. | 2009-10-15 |
20090257921 | Apparatus for Dispensing Material - An apparatus capable of dispensing drops of material with volumes on the order of zeptoliters is described. In some embodiments of the inventive pipette the size of the droplets so dispensed is determined by the size of a hole, or channel, through a carbon shell encapsulating a reservoir that contains material to be dispensed. The channel may be formed by irradiation with an electron beam or other high-energy beam capable of focusing to a spot size less than about 5 nanometers. In some embodiments, the dispensed droplet remains attached to the pipette by a small thread of material, an atomic scale meniscus, forming a virtually free-standing droplet. In some embodiments the droplet may wet the pipette tip and take on attributes of supported drops. Methods for fabricating and using the pipette are also described. | 2009-10-15 |
20090257922 | Penetratable Septum Cap - The present disclosure relates to a septum, e.g., for a sample container. A septum may comprise a first layer comprising a sheet of rubberized silicone compound and a second layer comprising a sheet of polytetrafluoroethylene. A second layer may be bonded to a first layer. The present disclosure also relates, in some embodiments, to a septum assembly. A septum assembly may comprise, for example, a septum and a cap. A cap may have an aperture (e.g., to permit insertion and/removal of a sampling device) A septum may be fitted into a cap such that the second layer is adjacent to the aperture. In some embodiments, the present disclosure further relates to a storage assembly. A storage assembly may comprise, for example, a septum assembly and vessel configured and arranged to contain a sample therein. A vessel may be capped by the septum assembly. | 2009-10-15 |
20090257923 | Odor Eliminating Cloth and Process for Producing the Same - An odor eliminating cloth according to this invention is characterized in that an odor eliminating composition containing a porous inorganic substance, a metallic oxide, and an inorganic silicon compound carrying a polyamine compound is fixed to at least a part of a cloth by means of a binder resin. With this odor eliminating cloth, any types of odors of basic gases, acidic gases, neutral gases, sulphur series gases contained in the air of a room can be effectively eliminated. | 2009-10-15 |
