What does CFT mean in MEDICAL

Capillary Filling Time (CFT) is the amount of time it takes for a liquid sample to fill a certain size capillary.

The speed at which samples fill a capillary directly impacts how quickly researchers can obtain results from their experiments. A longer CFT can adversely affect instrument performance, so it should be carefully considered when designing laboratory equipment like spectrophotometers and chromatography systems.

The rate at which liquids move through nanochannels can be measured by measuring the increase in pressure head over time as the liquid samples enter the channels. This measured pressure head versus time curve can then be used to calculate the CFT.

Several parameters may influence CFT, including channel diameter, liquid density, surface tension and others that depend on specific application conditions. Finding the optimal combination of these parameters is essential for achieving reliable results from laboratory instruments.

Different liquids have different properties which all work together to determine how quickly they will fill a capillary channel. For example, more dense liquids typically require more time to fill up a channel than less dense liquids due to their higher viscosity and lower surface tension. Furthermore, different liquids have dissimilar interactions with enveloping materials which also affects their CFT rate.
