The vacuum sieve tray (VST) method is based on the extraction of tritium from millimetre-scaled oscillating PbLi droplets falling inside a vacuum chamber.
And disposing of the vacuumed dirt and dust is easy, too, because the AirRam compresses it into tiny bales that can be plucked from the vacuum's waste tray.
This paper describes the quantitative analysis for the design of a tritium extraction system that uses liquid PbLi droplets in vacuum (Vacuum Sieve Tray, VST), for application to the ITER helium-cooled lithium lead (HCLL) test blanket system (TBS).
Concomitantly, it also eliminates the cost of setting up and operating commercial-scale vacuum chambers, robotic tray manipulators, biomass conveyer systems, and so forth.
Meanwhile, to protect the original structures of these precipitates from damage, the dry process was performed on a vacuum freezerdrye (FreeZone Stoppering Tray Dryer, Labconco) [49].
Ten 200 µl fractions (F1 F10) containing plaque supernatant proteins separated based on iso-electric point were harvested in a tray under vacuum according to the manufacturer's instructions.
Cellular lysates or homogenized tissue lysates are added to the tray and vacuum is applied under user interface control for a specific time and at an electronically controled pressure.
It's important to clean up spills promptly, wipe down countertops and high chair trays regularly, vacuum food crumbs, and scrub down the outside of containers for jams, syrups, and other sticky substances prior to putting them in the pantry," she writes.
Environmental tests include vibration testing, thermal cycles and thermal-vacuum cycles of every tray and tower as well as the verification of their electrical performance.
Many foods are packaged in clear, vacuum-formed polystyrene trays, owing to the high gas permeability and good water-vapour transmission of the material.
