Description
DURAN Manufactured from borosilicate glass 3.3
Due to the high wall-thickness of the vessels and the exact machining of the vacuum-tight ground joints on the lid and base, storage under vacuum is possible – even over extremely long periods.
To accelerate the drying process, a vacuum can be applied via the stopcock
Suitable for full vacuum (0 mbar)
Spare parts such as lids, bases, stopcocks and caps can be interchanged as required

Quartz Ware
Description
Vitreous Silica is the glassing modification of silcon dioxide with a purity of 99.9% in the transparent form and is called fused silica. All our silica ware products are made out of fused silica. Fused silica is completely unaffected by acids such as sulpuric, nitric and hydrochloric, however, it can be affected by hdrofluric acid and at high temperatures also by phosphoric acid. Hot alkalies and certain metallic oxides also react on fused silica.
Fused silica is boron free
They are of very low expansion and hence have excellent dimensional stability and thermal shock resistance
Technical Specifications:
- Electrical resistivity - (at 350°C) 7 x 107 ohm cm
- Average co-efficient of expansion - 5.5 x 10-7 / °C
- Softening point - 1685° C
- Annealing point - 1200° C
- Operating temperature (continuous) - 1050° C
- Operating temperature (intermittent) - 1350° C
Working temperature - 1950° C
Strain point - 1120° C
