SCHOTT Technical Glasses

31
FIOLAX ® clear, 8412
This glass belongs to the chemically resistant alkaline earth
containing borosilicate glass type. Its water and acid resistance
correspond to those of DURAN ® , and its alkali resistance
is even higher. Alkaline preparations up to pH values
of 12 can be stored and autoclaved in FIOLAX ® clear.
FIOLAX ® amber, 8414
Due to additions of iron and titanium oxides, this borosilicate
glass exhibits high light absorption in the blue and UV
spectral regions (see Figure 29). Sensitive pharmaceutical
preparations can therefore be effectively protected from
light in the critical wavelength region.
AR-GLAS ®
AR-GLAS ® with a CTE of 9.1 x 10 –6 /K belongs to the so-called
soda-lime glass family. The hydrolytical resistance is lower
compared to the neutral glasses FIOLAX ® and DURAN ® but
the glass is still stable enough to be used as a packaging
material for non-parental drugs i.e. pipets, vials for tablets,
and test tubes. An advantage is good workability and the
good price/performance ratio.
6.3 BOROFLOAT ® 33/SUPREMAX ®
BOROFLOAT ® 33 is a high-quality borosilicate glass with
impressive properties that make it suitable for a wide range
of applications. BOROFLOAT ® 33 is manufactured using the
microfloat process. SUPREMAX ® is a rolled borosilicate glass
that utilizes SCHOTT’s unique rolled sheet glass technology
to offer thicknesses that cannot be produced via the microfloat
process.
The chemical composition of BOROFLOAT ® 33/SUPREMAX ®
complies with the requirements for a typical borosilicate glass
according to DIN ISO 3585 and EN 1748 Pt. 1 respectively.
Like all borosilicate glasses, BOROFLOAT ® 33/SUPREMAX ®
demonstrate high resistance to water, many alkalis and
acids as well as organic substances. Its chemical resistance
is superior to that of most metals, even during long-term
use and at temperatures in excess of 100 °C (as used as sight
glasses in the chemical industry). Exposure to water and
acids only results in the leaching out of small amounts of
ions from the glass (as used in medicine and analytical engineering).

BOROFLOAT ® 33/SUPREMAX ® are produced using only the
finest natural raw materials and are therefore harmless to
human beings and the environment in accordance with the
requirements of the European guideline ROHS/2002/95.
The glass can be recycled for further use.
BOROFLOAT ® 33 is a highly versatile high-tech material suitable for
manifold applications in industry, engineering and research
SUPREMAX ® is available in a broad range of thicknesses
