Products made from AR-Glas¨

The Glass
AR-Glas is a clear glass of the third hydrolytic class and a soda lime glass type with a high content of alkali and alkaline earth oxides.

The Advantages
The variety of applications, the favorable price/efficiency ratio, good machine processing and dimensional accuracy are the outstanding properties of AR-Glas. All standard dimensions mentioned are available at short notice.

The Quality
The quality of our products is guaranteed by modern production methods and by a Quality System according to DIN ISO 9001/EN 29001, certified by TUV-Cert. The corresponding quality criteria are described in the Technical Terms of Delivery.

Further Processing
AR-Glas is characterized by its variety of fields of applications. Further processing is carried out in the fields of pharmacy, medicine, cosmetics, the food industry, by glassblowers and by manufacturers of laboratory equipment and technical products.

The Manufacturer
Schott-Rohrglas produces special glass tubing, capillary and rod in a wide range of dimensions for a great variety of application. Schott-Rohrglas is one of the leading manufacturers of special glass tubing world-wide with an annual production of over 50,000 tons. We produce special glass tubing for processors all over the world using the latest melting and production processes. Schott-Rohrglass GmbH is a member of the Schott Group.

Resistance to Thermal Shock

Resistance to thermal shock is not an exact, by defined physical quantity (for more details see ISO 718); it depends on the measuring method, the shape, the wall thickness and the surface and end properties of the glass object in question. Rapid temperature changes cause high temporary stress in the glass, meaning that rapid cooling processes are very dangerous, since in this case a thin outer layer of the glass is placed under tensile stress over the still hot inner core. Glass is much more susceptible to tensile stress than to compressive stress.

Outside Diameter and Wall Thickness

Outside diameter (OD) and wall thickness (WT).
In addition to the listed range, tubing with an OD of up to 70 mm and rod with an OD of up to 30 mm, plus other wall thicknesses, are available on request.

Length

Special lengths from 1200 to 4000 mm for tubing in the outside diameter range from 18 to 38 mm are available on request.

Out-of-Round

Out-of-Round according to ISO 1101 depends on the nominal outside diameter OD. The following maximum values have been laid down:

OD	Maximum value t
<25 mm	0.5 % of OD
25 - 35 mm	0.75 % of OD
>35 mm	1.0 % of OD
