Glass Flow Restrictors

Glass flow restrictors are utilized in many applications where an exact flow rate is needed. Glass flow restrictors are used in medication infusion pumps where they assure that the patient is neither over nor under medicated. Glass flow restrictors are also used to meter gases and to control the flow of saline in flush devices used in hemo-dynamic monitoring systems. Glass is commonly used as it is inert and does not interact with drugs as do other materials such as plastics. It is also dimensionally stable and will not change size or configuration during sterilization, storage or further processing.

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.
