In microfluidics,capillary tubesof 100µm diameter are currently used; if the liquid is water (γ=72mN/m), and using the approximate value cosθ~1/2, the capillary rise is of the order of 14cm, which is quite important at the scale of a microcomponent. ...
Trees are a perfect example in nature because tree sap travels up the bark of a tree against gravity through small and narrow tubes within the bark. What is capillary action in simple words? Capillary action occurs when the liquid climbs up a narrow straw or tube against gravity due to the...

7.7 From the Lab Bench to Industry: Microchip Capillary Electrophoresis Capillary electrophoresis (CE) is a well established separation method in analytical chemistry. At the conventional scale small bore tubes must be used, in order to quickly dissipate the heat that is generated by the current flo...
Method and capillary tube for treating blood sample Deoxygenation of a blood sample prior to determination of carbon monoxide hemoglobin is performed in a capillary tube containing a dry reducing agent. Ready for use capillary tubes having long storage life contain dry reducing agent and......
- Lab on a Chip - Miniaturisation for Chemistry & Biology 被引量: 22发表: 2011年 Flow regimes for the immiscible liquid–liquid displacement in capillary tubes with complete wetting of the displaced liquid The motion of two immiscible liquids in a capillary tube is analysed, theoretically and ...

The NASA mission Perfect Crystals used the microgravity environment on the International Space Station (ISS) to grow crystals of human manganese superoxide dismutase (MnSOD)—an oxidoreductase critical for mitochondrial vitality and human health. The mis
Variable selectivity of the Hitachi chemistry analyser chloride ion-selective electrode toward interfering ions. Clin Biochem 1994;27:37–41. 12. b. Many therapeutic drugs have been reported to bind to the gels used in SST tubes, although the effect varies from manufacturer to manufacturer. ...
Sensitive ELISA for C-reactive protein (CRP) was performed in a capillary tube based on simple vapor-phase surface chemistry. Amine surfaces were produced in capillary tubes in two different methods using 3-aminopropyltriethoxysilane (APTES) in liquid and vapor phases. Those amine surfaces were ...
