CAPILLARY TUBING

Accu-Glass manufactures 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.  These small tubes are used in liquid measurement, liquid transfer and sample collection applications.  Examples include:

	Micropipettes where a liquid is drawn into a tube with a predetermined volume and then dispensed as a known aliquot.
	Small blood collection tubes which are used to draw blood from a finger stick.

Accu-Glass manufactures capillary glass tubing from molten glass and draws 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 fill line and color coded to designate volume calibration. 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.

Finally, Accu-Glass can package the tubes in the final consumer packaging or bulk pack when our customers prefer to final package themselves.

Other Accu-Glass precision glass tube products are used in infusion pumps, saline flush devices, electronic components, fiber optics, photonics and thermometer tubing.  These types of precision glass tubes include micro-bore flow restrictors, infrared absorbing glass tubing, ferrules, collimators, prismatic glass tubing, flat glass tubing and round glass tubing for scientific and industrial applications.

Accu-Glass takes pride in designing and manufacturing glass to exceed our customers' expectations.
