Venous blood should not be collected into a capillary tube or a micro-tube.
From blood collected into a capillary tube via fingerstick, the simple to use test detects and quantifies a wide range of HCV genotypes within 58 minutes.
One of the most broadly used methods was proposed by Yu and Cheng [23]; their model was developed based on the tortuous fractal capillary tube model, although no empirical parameters were introduced in their model.
The drop-in replacement entailed oil change (in the R-22 unit), charge optimization, and capillary tube length optimization.
Key statement: A tire having a radial carcass reinforcement, having at least one layer of reinforcing elements, said tire comprising a crown reinforcement, which is itself covered radially with a tread, said tread being joined to two beads via two sidewalls, wherein at least 90% of the reinforcing elements of at least one layer of the carcass reinforcement are non-wrapped metal cords having in what is called the permeability test a flow rate of less than 20 [cm.sup.3]/min., wherein at least 1% of the reinforcing elements of said at least one layer of the carcass reinforcement are capillary tubes and wherein, in a plane of section perpendicular to the axis of the capillary tube, the ratio of the open area to the area of material is greater than 0.4%.
The Quantitative Buffy Coat (QBC) technique involves the use of special fluorochrome dye to highlight malaria parasite at predictable location of a specially prepared capillary tube. This method, though faster and easier is however much more costly and species identification is difficult by this technique.[2] This study was carried out in a teaching hospital in North-east India to evaluate the QBC technique against the conventional Giemsa stained smears in diagnosis of malaria parasite.
The C[O.sub.2] withdraws heat from the steel of the mold and escapes out of the expansion room in gaseous form through an annular gap between the hole and capillary tube. Given the purity of LC[O.sub.2] supplied for this application (typically >99.98%), there is little danger of residue build-up or contamination of the hole as there would be with water cooling.
Before the difference in the molecules' mass-to-charge ratio (m/z) is measured for quantification, the ions typically pass through a capillary tube to keep the sample ionized.
The expansion happens in a carefully designed restriction called a capillary tube. The compressor either runs on full capacity or is idle.
To use the device, a patient pricks his or her finger to draw blood into a capillary tube then connects the tube to a microfluidic cassette.
Capillary tube formation was observed using a phase contrast microscope during the culture period.
