摘要:
Described is a rotary valve including a stator element and a rotor element. The stator element defines a first inlet passage, a second inlet passage, and a first outlet passage, respectively, having a first inlet port, second inlet port and first outlet port in a stator face. The rotor element has a rotor face in contact with the stator face and has a first channel and a second channel formed therein. The rotor element is rotatably movable about a rotational axis to at least a first position and a second position. In the first position, the first inlet port is fluidly coupled to the first outlet passage by the first channel and the second inlet port is fluidly coupled to the first outlet passage by the second channel. In the second position, the first inlet port is fluidly coupled to the first outlet passage by the first and second channels.

摘要:
An apparatus for chemical separations includes a first substantially rigid microfluidic substrate defining a first fluidic port; a second substantially rigid microfluidic substrate defining a second fluidic port; and a coupler disposed between the first and second substrates, the coupler defining a fluidic path in fluidic alignment with the ports of the first and second substrates. The coupler includes a material that is deformable relative to a material of the first substrate and a material of the second substrate. The substrates are clamped together to compress the coupler between the substrates and form a fluid-tight seal.

An apparatus for use in a chromatography system includes a first microfluidic substrate having a first fluidic channel. One end of the first fluidic channel terminates at a first fluidic port on a first side of the first microfluidic substrate and an opposite end of the first fluidic channel terminates at a second fluidic port on a second side of the first microfluidic substrate. A second microfluidic substrate has a second fluidic channel. One end of the second fluidic channel terminates at a first fluidic port on a first side of the second microfluidic substrate. The first side of the second microfluidic substrate abuts the second side of the first microfluidic substrate such that the fluidic port of the second microfluidic substrate aligns with one of the fluidic ports of the first microfluidic substrate and the alignment produces a fluidic path comprised of the first and second fluidic channels.

An apparatus includes a portable housing and a plurality of separately operable microfluidic emitters disposed within the housing. Each microfluidic emitter h an inlet for receiving a liquid and an outlet for emitting a spray. Each microfluidic emitter is movable within the portable housing between a first position in which the outlet of that microfluidic emitter is fully retracted within the portable housing and a second position in which the outlet of that microfluidic emitter projects out of the portable housing. The portable housing with the multiple emitters is adapted to be detachably coupled to another housing portion. This housing portion includes a microfluidic substrate with a channel for transporting an eluent and an outlet aperture for emitting the eluent. The inlet of one of the emitters is detachably coupled to the outlet aperture of the microfluidic substrate.

Surgical devices permitting a surgeon to access repeatedly tissue at a particular surgical site in a patient to perform multiple surgeries over time. The devices have two substantially planar and parallel leaves that are sterile, nonresorbable, and biocompatible. Each leaf forms a continuous structure and defines the entire longitudinal length of the device to accommodate the size and location of the surgical site. A base member is located in situ and adjacent the surgical site. An anchoring surface secures the device to the tissue of the patient at the surgical site. The leaves have a conjoined portion such that a manual force is required to separate the leaves, thereby expeditiously creating a pathway through which access to the tissue at the surgical site is realized with minimal tissue dissection, and the proximal ends of the leaves are not conjoined to facilitate separation of the leaves and creation of the pathway.

Methods of manufacturing glass sheets with manufacturing systems that including platinum-containing components are provided. The method includes providing a barrier coating to reduce the hydrogen permeability of the platinum-containing components which reduces the propensity for blistering of glass sheets made using the components.
