Glass Tubing Materials


Molten glass allows for unlimited design possibilities. Accu-Glass specializes in the following glass types:
  • Borosilicate
  • Soda Lime
  • Lead Free Glass
  • IR Absorbing Glass

Specialty compositions are also possibilities to solve a variety of engineering problems. Take advantage of the unique chemical and mechanical characteristics of glass in your design:
  • Light transmittable or Transparent
  • Optically stable
  • Chemically inert
  • Non-porous or Impermeable
  • Dielectric or does not conduct electrical energy
  • Low thermal conductivity
  • High compressive strength
  • Environmentally friendly
  • Inexpensive and Disposable
  • Tamper resistant
  • Sterilizable

Borosilicate Glass Tubing

Borosilicate Glass Tubing

Accu-Glass Tubing


Accu-Glass melts two borosilicate glass compositions. One is a low-expansion borosilicate glass that conforms to USP Type I and ASTM Type I, Class A requirements. The second is an alumino-borosilicate glass that conforms to USP Type I and ASTM Type I, Class B requirements. Both compositions offer high chemical resistance for use in the medical and pharmaceutical industries. Uses include crushable ampoules, flow restrictors, fiber optic components, and electrical applications.


Soda Lime Glass Tubes

Accu-Glass Tubes


Accu-Glass melts a pharmaceutical grade soda lime glass used in the medical, clinical, laboratory, and pharmaceutical industries (conforms to USP Type III and ASTM Type II). This composition has a wide range of uses, including capillary, hermatocrit, volumetric, flow restrictors and micro-pipette tubes, with various coatings and calibrated markings, and crushable ampoules.


Lead Free Glass Tubing

Accu-Glass melts an environmentally friendly composition used in lighting applications, thermometer tubing and other specialty tubing. Lead Free Glass sleeves are excellent for semiconductor encapsulation, such as silicon diodes, or reed switch packaging. Comply with the Restriction of Hazardous Substances Directive (RoHS) directive using Accu-Glass lead free glass tubing.


IR Absorbing Glass Sleeves
