  • Patent number: 11819852
    Abstract: A reagent preparation assembly includes a body and a reaction chamber adjacent the body, the reaction chamber includes a reagent therein, such as a lyophilized reagent. An access port extends into the reaction chamber, and the access port is configured to receive an instrument. A seal extends across a portion of the reaction chamber and the access port. A reconstitution assembly is movably coupled with the body. The reconstitution assembly includes a plunger, a syringe and a piston. The plunger is movably coupled with the body. The syringe is selectively engaged with the plunger. The syringe includes a solution reservoir containing a solution, and movement of the syringe pierces the seal. The piston is selectively engaged with the plunger, and the piston is movably coupled within the syringe. Movement of the piston pushes the solution into the reaction chamber.

  • Publication number: 20210138471
    Abstract: A reagent cartridge includes a cartridge body configured to store a solid reagent, the cartridge body having a reagent well accessible through an access port. A seal plate is proximate the access port, the seal plate extends away from the access port to a seal plate edge remote from the access port. The reagent cartridge includes an isolation envelope surrounding the reagent well. The isolation envelope includes a seal membrane covering the access port, at least one isolation wall, and at least one isolation cavity interposed between the isolation wall and the well sidewall. One or more reagent cartridges are received in a cartridge magazine. The cartridge magazine includes at least one complementary profile seat configured to receive the one or more reagent cartridges having a corresponding cartridge profile.

  • Publication number: 20020174562
    Abstract: A lyophilizer system is adapted for operation in a first mode or a second mode with microwave assisted drying. The system includes a lyophilizing chamber, including shielding from microwaves. The chamber is connected to a pressure controller for controlling vacuum in the lyophilizing chamber and a device for trapping water vapor. One or more microwave generators, direct microwaves into the lyophilizing chamber. Refrigeration units lower the temperature of the lyophilizing chamber and condenser. The chamber environment maintains a temperature and a pressure that facilitates sublimation in the chamber in a first mode, and for creating a chamber environment having vacuum and temperature such that when combined with microwaves directed into the chamber, facilitates sublimation in the chamber in a second mode. The chamber has arc inhibiting surfaces and shielding and a corona discharge detection and control system, including optical, thermal and other detection systems.

  • Patent number: 5979352
    Abstract: A dock system storage device includes a base and an enclosure including doors at one side. The enclosure is constructed of laminated panels connecting at their edges to connecting channel members. The storage device has a width and length substantially equal to dock system sections. The storage device connects to an edge of the dock system with connectors below an upper surface of the dock sections. The storage device includes legs or pontoons supporting the device independently of the dock sections.
