Precision Fuse Glass Tube

soda lime glass fuse tube, electronic sealing tube
Precision fuse glass tube
Small diameter thin-walled precision glass tubing which, by design, exhibits capillary action. Capillary action is the movement of a liquid into a tube based on its surface tension. Glass Micro Bore Tube Features
Capillary glass tubing from molten glass drawn it into long lengths. These are then cut to a specific length and the ends of the tubes are flame polished. Many times the tubes are marked with a color coded fill line to designate volume calibration for applications like disposable glass micropipettes.
In the case of blood collection tubes (called hematocrit tubes), these are processed in the same manner; However, some are coated with heparin (an anticoagulant) so that blood does not clot when drawn.
