An axial-flow molecular pump has a first active magnetic bearing for axially supporting and controlling a pump member comprised of a set of permanent magnets on the upper end of the pump member cooperating with
24] numerically simulated the flow field of fish as they passed through a mixer pump and analyzed that the shear rate did not cause damage to the fish body. Long

Buffer was injected into the flow-cell chamber at a constant flow-rate of 20 μL/min using a syringe pump. Experiments were all performed at room temperature. Shift in the resonance frequency (Δf) and dissipation (ΔD) can be, in first approximation, attributed to changes in deposited ...
Because ventricular geometry may be affected by the pump position, 3D studies for the HeartMate 3 may be needed. However, this device is less likely to cause apical deformation than axial flow pumps due to intrathoracic freedom versus sub-diaphragmatic anchoring, the latter resulting in inferior ...
To investigate the rates of internal electron transfer within the supercomplex upon reaction with O2 we used the flow-flash technique. The reduced supercomplex with CO bound to heme a3 was mixed with an O2-saturated buffer in a stopped-flow apparatus. Binding of O2 is rate-limited by the CO...
To extract the spatial barcodes, arrays were sequenced using Bioptechs FCS2 flow cells with an RP-1 peristaltic pump (Rainin) and a modular valve positioner (Hamilton MVP). During sequencing, flow rates between 1 and 3 ml min−1 were used. Imaging was obtained with Nikon Plan Apo ...
The turbo-molecular pump is an axial flow pump and comprises a multi-stage assembly of moving vanes 4 rotating at high speed surrounded by stator vanes 4A. Gas molecules entering the pump through an inlet opening 1 strike and reflect off the surfaces of the moving vanes and stator vanes, ...
it is possible to reduce the suction resistance without increasing the size in the axial direction of the turbo-molecular pump1. As illustrated in FIG. 1, disposing the protection net50with the recessed side of the mesh section52facing the rotor blades6enables the separation distance between the...
Still other advantages may include (but not limited to): increased pump down and landing speeds/flow rates; allows for larger stage counts; more compact design that drastically reduces dart length at larger stage counts; reduced impact forces when counting allowing for use of softer materials and...
