Physical properties
Temperature resistance on being heated up and
thermal shock resistance:
The maximum permissible operating temperature for DURAN
is 500 C. Abobe a temperature of 525 C the glass begins to
pass from the solid to the viscous state. As it has a very low
linear coefficient of expansion a feature of DURAN is its high
thermal shock resistance up to T=100K. This means that for
a temperature change of 1K, the glass changes by only
3,3.10-6 relative units of length.
Temperature resistance at freezing temperatures :
DURAN can be cooled down to the maximum possible negative
temperature and is also suitable for use in liquid air (approx.-192 C).
Ingeneral DURAN products are recommended for use down to -70C.
When cooling down and thawing care must be taken to avoid
a temperature difference of more than 100K. When freezing
substances in such items as DURAN bottles or DURAN test tubes
the container should only be filled to a maximum of 3/4 of its
capacity and it must be frozen slanted maximum of -40C
Use in the microwave : DURAN laboratory glass is suitable
for use in microwaves. This applies also to plastic coated
DURAN products. |
