Abstract: A fluid supply system adapted for vacuum and pressure cycling of fluid, including a transfer vessel adapted to supply a process canister with fluid drawn from a bulk canister under a vacuum, wherein delivery of fluid from the transfer vessel to the process canister is accomplished with positive pressure. A method is also disclosed of delivering fluid, including drawing fluid under vacuum from a bulk canister and pressurizing the transfer vessel to effect dispensing of the fluid into a process canister for delivery to a location of use.

Abstract: The present disclosure, in one embodiment, relates to a dispenser including a dispense assembly having a head assembly, and also including a collapsible liner that contains a material to be dispensed, the liner detachably secured to the dispense assembly with the head assembly in fluid communication with the liner, wherein the material in the liner is dispensed out the liner and through the head assembly.

Abstract: A method for removing headspace gas from a liner-based assembly. The liner-based assembly may generally include an overpack, a liner positioned within the overpack and containing a material and headspace gas, and a closure for sealing the liner. The method may include providing a one-way valve in fluid communication with the interior of the liner and permitting flow in a direction out of the interior of the liner, and applying a vacuum to the one-way valve to evacuate headspace gas from the interior of the liner. In some embodiments, The liner-based assembly may also include a port in fluid communication with an annular space between the overpack and liner, and the method may include capping the port, for example, during application of the vacuum to the one-way valve.

Abstract: The present disclosure relates to novel and advantageous disposable dispensers. The dispenser may include a dispense assembly comprising an outlet channel in fluid communication with a terminal apparatus, and a pressure source providing a limited supply of fluid or gas, and also includes a collapsible liner that contains a material to be dispensed, the liner detachably secured to the dispense assembly with the outlet channel in fluid communication with an interior of the liner, wherein the material in the liner is dispensed out the liner and through the outlet channel to the terminal apparatus.

Abstract: An aggregometer has a radiation path along which radiation can pass, a sample receiving area located along the radiation path, a short-wavelength LED that transmits radiation along the radiation path through the sample receiving area, a detector positioned along the radiation path for detecting radiation transmitted from the short-wavelength LED, and a processor that controls intensity of radiation transmitted from the short-wavelength LED.

Abstract: Vertical electromagnetic stirring is used to produce low shear, stress, turbulent and chaotic mixing of a liquid material or suspension in a container regardless of the volume or container geometry. Movement of a magnetic stir bar is controlled by multiple magnetic fields. The magnetic fields are produced by a series of sequentially or non- sequentially activated inductor coils which produce asymmetrical stirring dynamics and random motions of the stir bar, causing the liquid material to be gently and effectively mixed throughout the container. Moving the stir bar in random and irregular patterns during the stirring operation creates turbulent and chaotic mixing dynamics. The stir bars used for supporting vertical magnetic stirring are specifically designed to optimize the effectivity of the mixing process by maximizing the length of the stir bar to quickly and gently mix the materials.

Abstract: A tool and method for flaring plastic tubing provides efficiency and rapidity. The tool has interchangeable clamping portions for different sized tubing, different manually inserted mandrels for the different sized tubing, and automated clamping, heating, and flaring operations.
